Cybersecurity and Information Sharing: Legal Challenges and Solutions

Summary

Over the course of the last year, a host of cyberattacks has been perpetrated on a number of high

profile American companies. The high profile cyberattacks of 2014 and early 2015 appear to be

indicative of a broader trend: the frequency and ferocity of cyberattacks are increasing, posing

grave threats to the national interests of the United States. While considerable debate exists with

regard to the best strategies for protecting America’s various cyber-systems and promoting

cybersecurity, one point of general agreement amongst cyber-analysts is the perceived need for

enhanced and timely exchange of cyber-threat intelligence both within the private sector and

between the private sector and the government. Nonetheless, there are many reasons why entities

may opt to not participate in a cyber-information sharing scheme, including the potential liability

that could result from sharing internal cyber-threat information with other private companies or

the government. More broadly, the legal issues surrounding cybersecurity information sharing—

whether it be with regard to sharing between two private companies or the dissemination of

cyber-intelligence within the federal government—are complex and have few certain resolutions.

In this vein, this report examines the various legal issues that arise with respect to the sharing of

cybersecurity intelligence, with a special focus on two distinct concepts: (1) sharing of cyberinformation within the government’s possession and (2) sharing of cyber-information within the

possession of the private sector.

With regard to cyber-intelligence that is possessed by the federal government, the legal landscape

is relatively clear: ample legal authority exists for the Department of Homeland Security (DHS)

to serve as the central repository and distributor of cyber-intelligence for the federal government.

Nonetheless, the legal authorities that do exist often overlap, perhaps resulting in confusion as to

which of the multiple sub-agencies within DHS or even outside of DHS should be leading efforts

on the distribution of cyber-information within the government and with the public. Moreover,

while the government has wide authority to disclose cyber-intelligence within its possession, that

authority is not limitless and is necessarily tied to laws that restrict the government’s ability to

release sensitive information within its possession.

With regard to cyber-intelligence that is possessed by the private sector, legal issues are clouded

with uncertainty. A private entity that wishes to share cyber-intelligence with another company, an

information sharing organization like an Information Sharing and Analysis Organization (ISAO)

or an Information Sharing and Analysis Centers (ISAC), or the federal government may be

exposed to civil or even criminal liability from a variety of different federal and state laws.

Moreover, because of the uncertainty that pervades the interplay between laws of general

applicability—like federal antitrust or privacy law—and their specific application to cyberintelligence sharing, it may be very difficult for any private entity to accurately assess potential

liability that could arise by participating in a sharing scheme. In addition, concerns may arise with

regard to how the government collects and maintains privately held cyber-intelligence, including

fears that the information disclosed to the government could (1) be released through a public

records request; (2) result in the forfeit of certain intellectual property rights; (3) be used against a

private entity in a subsequent regulatory action; or (4) risk the privacy rights of individuals whose

information may be encompassed in disclosed cyber-intelligence.

The report concludes by examining the major legislative proposal—including the Cyber

Intelligence Sharing and Protection Act (CISPA), Cybersecurity Information Sharing Act (CISA),

and the Cyber Threat Sharing Act (CTSA)—and the potential legal issues that such laws could

prompt.

Cybersecurity and Information Sharing: Legal Challenges and Solutions

Introduction

Over the course of the last year, a host of cyberattacks1 have been perpetrated on a number of

high profile American companies. In January 2014, Target announced that hackers, using

malware,2 had digitally impersonated one of the retail giant’s contractors,3 stealing vast amounts

of data—including the names, mailing addresses, phone numbers or email addresses for up to 70

million individuals and the credit card information of 40 million shoppers.4 Cyberattacks in

February and March of 2014 potentially exposed contact and log-in information of eBay’s

customers, prompting the online retailer to ask its more than 200 million users to change their

passwords.5 In September, it was revealed that over the course of five months cyber-criminals

tried to steal the credit card information of more than fifty million shoppers of the world’s largest

home improvement retailer, Home Depot.6 One month later, J.P. Morgan Chase, the largest U.S.

bank by assets, disclosed that contact information for about 76 million households was captured

in a cyberattack earlier in the year.7 In perhaps the most infamous cyberattack of 2014, in late

November, Sony Pictures Entertainment suffered a “significant system disruption” as a result of a

“brazen cyber attack”8 that resulted in the leaking of the personal details of thousands of Sony

employees.9 And in February of 2015, the health care provider Anthem Blue Cross Blue Shield

For purposes of this report, the term “cyberattack” refers to a deliberate infiltration of a computer system or network

with the intent to either extract or destroy confidential information or to destroy the functioning of the system or

network. See Jay P. Kesan and Carol M. Hayes, Mitigative Counterstriking: Self-Defense and Deterrence in

Cyberspace, 25 HARV. J.L. & TECH. 429, 439-446 (2012). It should be noted however the exact contours of what the

term “cyberattack” entails is subject to much debate. See id. at 439 (“The modern lexicon considers all types of online

intrusions to be cyberattacks, even though many commentators would assert that such indiscriminate use of the term

‘cyberattack’ is incorrect.”); see also William A. Owens, Kenneth W. Dam, and Herbert S. Lin, et al., Overview,

Findings, and Recommendations, in TECHNOLOGY, POLICY, LAW, AND ETHICS REGARDING U.S. ACQUISITION AND USE

OF CYBERATTACK CAPABILITIES 10-11(2009) (distinguishing between the terms “cyberattack” and “cyber

exploitation”); Oona A. Hathaway et al., The Law of Cyber-Attack, 100 CALIF. L. REV. 817, 823 (2012). (“The absence

of a shared definition has made it difficult for analysts from different countries to develop coordinated policy

recommendations and for governments to engage in coordinated actions.”)

disclosed that a “very sophisticated attack” obtained personal information relating to the

company’s customers and employees.10

The high profile cyberattacks of 2014 and early 2015 appear to be indicative of a broader trend:

the frequency and ferocity of cyberattacks are increasing,11 posing grave threats to the national

interests of the United States. Indeed, the attacks on Target, eBay, Home Depot, J.P. MorganChase, Sony Pictures, and Anthem were only a few of the many publicly disclosed cyberattacks

perpetrated in 2014 and 2105.12 Experts suggest that hundreds of thousands of other entities may

have suffered similar incidents during the same period,13 with one survey indicating that 43% of

firms in the United States had experienced a data breach in the past year.14 Moreover, just as the

cyberattacks of 2013—which included incidents involving companies like the New York Times,

Facebook, Twitter, Apple, and Microsoft15—were eclipsed by those that occurred in 2014,16 the

consensus view is that 2015 and beyond will witness more frequent and more sophisticated cyber

incidents.17 To the extent that its expected rise outpaces any corresponding rise in the ability to

defend against such attacks, the result could be troubling news for countless businesses that rely

more and more on computers in all aspects of their operations, as the economic losses resulting

from a single cyberattack can be extremely costly.18 And the resulting effects of a cyberattack can

have effects beyond a single company’s bottom line. As “nations are becoming ever more

dependent on information and information technology,”19 the threat posed by any one cyberattack

can have “devastating collateral and cascading effects across a wide range of physical, economic

and social systems.”20 With reports that foreign nations—such as Russia, China, Iran, and North

Korea –may be using cyberspace as a new front to wage war,21 fears abound that a cyberattack

could be used to shut down the nation’s electrical grid,22 hijack a commercial airliner,23 or even

launch a nuclear weapon with a single keystroke.24 In short, the potential exists that the United

States could suffer a “cyber Pearl Harbor,” an attack that would “cause physical destruction and

loss of life”25 and expose—in the words of one prominent cybersecurity expert–“vulnerabilities of

staggering proportions.”26

Given the growing and potentially grave threat posed by cyberattacks, one of the stated priorities

of the President and congressional leadership is to enact laws that ensure that both the public and

private sector are prepared to meet the cyber-challenges of the future.27 While considerable debate

exists with regard to the best strategies and methods for protecting America’s various cybersystems,28 one point of “general agreement” amongst cyber-analysts is the perceived need for

between the private sector and the government.30 The argument for the real time sharing of cyberintelligence—which could include the sharing of vulnerability data (the vulnerabilities an intruder

might exploit to gain access to a computer system), threat data (the types of malware circulating

the Internet and the nature of the threats a given entity has faced), and countermeasure data (the

steps an entity has taken to prevent or mitigate the effects of a cyberattack)31—is grounded in the

idea that effective cybersecurity depends upon robust knowledge about potential threats and wide

dissemination of the best practices and strategies to combat such threats.32

Despite widespread agreement about the need for enhanced cyber-information sharing, there is

similar agreement among cyber-experts that current public and private sector information sharing

efforts are simply inadequate.33 While there may be many reasons why entities may opt to not

deter or mitigate a cyber-attack, including vulnerability, threat, and countermeasure data. See infra note 31 and

accompanying text.

information sharing should be facilitated, such as the need for privacy and civil liberty protections for information

shared amongst private and public entities. See, e.g., Erin Kelly, Obama, Congress may find cybersecurity consensus,

USA TODAY (January 25, 2015), available at http://www.usatoday.com/story/news/politics/2015/01/25/cybersecurityinformation-sharing-bill/22229049/ (“That doesn't mean that there are no conflicts between the White House and

See Sales, supra note 26, at 1546. Threat data may consist of “signatures,” patterns of network traffic deployed to

activity. See Jeremy J. Broggi, Building on Executive Order 13,636 to Encourage Information Sharing for

Cybersecurity and Information Sharing: Legal Challenges and Solutions

participate in a cyber-information sharing scheme,34 a primary rationale for such a decision

concerns the potential liability that could result from sharing internal cyber-threat information

with other private companies or the government. Indeed, in a recent survey of over 700

information technology security practitioners, half of the respondents listed worries about

“potential liability [from] sharing” as the main reason for not participating in an initiative for

exchanging threat information.35 More broadly, the legal issues surrounding cybersecurity

information sharing—whether it be with regard to sharing between two private companies or the

dissemination of cyber-intelligence within the federal government—are complex and have few

certain resolutions. In this vein, this report analyzes the major legal issues regarding cyber-threat

information sharing by beginning with a discussion of the current legal authorities respecting the

exchange of cyber-intelligence. Included in this discussion will be an examination of the various

sources of liability that could result from information sharing. The report concludes by discussing

several of the major legislative proposals aimed at reforming federal cyber-information sharing

laws and potential legal issues that such laws could prompt.

Conceptualizing the Legal Issues Regarding Cyber

Information Sharing

While often the concept of “cyber-information sharing” is thought of as a monolith, the sharing of

cyber-intelligence touches on three related, but distinct concepts. First, cyber-information sharing

is often used in the context of describing efforts to promote the dissemination of cyberintelligence from the federal government to other government entities or the private sector. This

sort of cyber information sharing would occur, for example, when the Federal Bureau of

Investigation (FBI) provides the Department of Homeland Security (DHS) or privately owned

banks with the IP addresses of computers known to have launched distributed denial of service

(DDoS) attacks against other entities within the financial sector.36 Second, cyber-threat

information sharing also embraces the concept of private entities sharing cyber-intelligence with

each other, such as when several companies in a particular sector establish a formal exchange or

34

Among these concerns include worries about compromising proprietary information, a desire to not aid competitors,

losing customer goodwill, and reputational harms that may occur if an entity discloses details about a prior cyberattack.

See Sales, supra note 26, at 1549; see also Derek E. Bambauer, Ghost in the Network, 162 U. PA. L. REV. 1011, 1046

(2014) (“Firms have significant incentives not to disclose breaches or attacks. Revealing lapses could have reputationrelated market effects. Publicly traded companies ... suffer drops in share price immediately after revealing security

breaches. Disclosing vulnerability information risks further dissemination (even if inadvertent) that could lead to

additional attacks ... firms may not want to aid competitors either by reducing their information security costs or by

protecting them from the same attack.”).

35

See Ponemon Institute—Threat Intelligence, supra note 33, at 3.

36

See, e.g., Cybersecurity: Enhancing Coordination to Protect the Financial Sector, Hearing Before Senate Committee

on Banking, Housing, and Urban Affairs, 113th Cong. (2013) (statement of Joseph M. Demarest, Assistant Director,

Cyber Division, Federal Bureau of Investigation, available at http://www.fbi.gov/news/testimony/cyber-securityenhancing-coordination-to-protect-the-financial-sector (“The FBI worked closely with Department of Homeland

Security (DHS) to issue Joint Indicator Bulletins (JIBs) to the U.S. banks, which included thousands of IP addresses

that participated in the attacks. The U.S. banks used the IP addresses to better mitigate future incidents, thus helping to

ensure their business operations could proceed with less interruption of service to their customers.”); see generally

Sales, supra note 26, at 1547 (“[T]he government’s highly resourceful intelligence agencies are simply better than the

private sector at detecting intrusions by sophisticated adversaries like foreign militaries and developing

countermeasures. The government can provide these firms with the signatures of malware used in previous attacks, and

firms can use the signature files to detect future intrusions.”).

Cybersecurity and Information Sharing: Legal Challenges and Solutions

formal agreements to share relevant cyber-information with each other.37 Finally, cyberinformation sharing also describes when private entities share cyber-threat information in their

possession with the government. Such information sharing could occur, for example, when

private security firms report to DHS details about potential cyber-vulnerabilities unearthed in

research.38 While collectively these three variants on the concept of cyber-information sharing

have some commonalities, each also raises separate legal challenges that may impede cyberintelligence dissemination more generally.

Sharing Cyber-Information in the Possession of the

Government

Perhaps the area in which there is the most legal clarity with respect to cyber-information sharing

pertains to the authority of the federal government –and its subcomponents—to disseminate cyber

threat information within the government and with the private sector. Two central components of

DHS lead efforts to distribute cyber-intelligence to others in the government39 and the private

sector.40

First, the Office of Intelligence and Analysis (I&A), an entity established under Section 201 of

the Homeland Security Act of 2002 (Homeland Security Act or the Act),41 is generally authorized

to “access and receive” information and intelligence from “agencies of the Federal Government,

State and local government agencies (including law enforcement agencies), and private sector

entities”42 in order to “identify and assess” “terrorist threats to the homeland” and “actual and

potential vulnerabilities to the homeland.”43 In addition, the I&A is responsible for “integrat[ing]

relevant information, analysis, and vulnerability assessments” and disseminating such

information in “both classified and unclassified formats, as appropriate” to “other agencies of the

The White House recently announced the creation of the Cyber Threat Intelligence Integration Center (CTIIC), an

agency housed within the Office of the Director of National Intelligence (DNI) and will be modelled off of the National

Counterterroism Center (NCTC) to share cyber-intelligence across various entities within the federal government. See

infrastructure or key resources;” (2) a violation of federal or state or local criminal law; and (3) appears to be intended

to either (a) intimidate or coerce a civilian population, (b) influence the policy of a government by intimidation or

Federal Government, State, and local government agencies and authorities, the private sector, and

other entities.”44 In turn, pursuant to 6 U.S.C. Section 143, DHS, through I&A, is required to

provide to state and localities “analysis and warnings related to threats to, and vulnerabilities of,”

“critical information systems,”45 a term of art presumably46 controlled by the Homeland Security

Act’s definition for the term “critical infrastructure”:

[S]ystems ... so vital to the United States that the incapacity or destruction of such systems ...

would have a debilitating impact on security, national economic security, national public

health or safety, or any combination of those matters.47

Moreover, DHS is authorized “upon request” to provide the same “analysis and warnings” to

“private entities that own or operate critical information systems.”48 In practice, the I&A has

primarily exercised its authority by focusing its efforts on analyses of cyber-threat information

and the distribution of those analyses to various public and private entities.49

In addition to the I&A, DHS’s National Protection and Programs Directorate (NPPD) and its

subcomponents play perhaps an even more important role with respect to the sharing of cyberthreat information with other government and private entities.50 Within the NPPD exists the

Office of Cybersecurity and Communications (CS&C), an office Congress created in 200651 that

is tasked with overseeing the “security, resiliency, and reliability of the nation’s cyber and

communications infrastructure.”52 To execute this mission, CS&C, supports “24x7 information

sharing, analysis, and incident response” through the National Cybersecurity and Communication

Integration Center (NCCIC or Center).53 Established in 2009, the NCCIC is a “24-hour, DHS-led

information sharing programs, including the Cyber Information Sharing and Collaboration

the Under Secretary” for the NPPD.59 Specifically, the NCPA confirmed that the NCCIC’s

functions include serving as an “interface” for the “real-time” “sharing of information related to

cybersecurity risks, incidents, analysis, and warnings between Federal and non-Federal

entities.”60 Furthermore, the NCPA directs the Center to provide a number of additional services,

such as technical assistance, risk management support, and incident response capabilities to both

public and private entities.61 The NCPA requires NCCIC to include representatives of federal

agencies, state and local governments, and private sector owners and operators of critical

information systems,62 while still providing the Under Secretary for the NPPD with discretion

with respect to the precise makeup of the Center.63 In February of 2015, in keeping with NCCIC’s

statutory role, President Obama, in an Executive Order, mandated that the Center “engage in

continuous, collaborative, and inclusive coordination with” Information Sharing and Analysis

Organizations (ISAOs),64 a formal or informal entity or collaboration created or employed by

public or private sector organizations that gather, analyze, and disseminate cyber-threat

information.65

The Homeland Security Act, as amended by the NCPA, provides significant authority for DHS to

disseminate a wide range of cyber-threat intelligence within the possession of the federal

government to other government agencies and to the private sector. Earlier iterations of the

Homeland Security Act seemingly cabined DHS’s authority to collect and share cyberintelligence only to the extent such information respected a “terrorist threat”66 or would pertain to

“critical information systems.”67 In contrast, the NCPA provides NCCIC the authority to share

cyber-information to the extent that such information relates to “cybersecurity risks,”68 a term of

art that encompasses any “threats” and “vulnerabilities” to information systems and “any related

consequences caused by or resulting” from a host of actions that could compromise an

information system or the information stored on an information system.69 In other words, given

Cybersecurity and Information Sharing: Legal Challenges and Solutions

DHS’s discretion in designating various entities to participate in the NCCIC,70 it appears DHS has

fairly broad authority to disseminate federal cyber threat information throughout the private

sector, regardless of whether the information pertains to an industry that is “so vital to the United

States that the incapacity or destruction” of that industry’s assets or information systems would be

“debilitating” to the country.71 In fact, one issue that has been raised by commentators is whether

the statutory authority allotted to the various entities within DHS—such as I&A and NPPD—to

engage in cyber-information sharing is so broad and ill-defined that confusion could result

internally within the Department as to who the central actor should be with respect to the sharing

of federal cyber-intelligence.72 The same argument could plausibly be made with respect to the

authority to disseminate cyber-intelligence amongst the various entities of the federal

government, as entities like the I&A73 and NPPD74 within DHS and new entities outside of DHS,

like the newly formed Cyber Threat Intelligence Integration Center (CTICC)75 appear to possess

overlapping legal authorities with respect to the internal sharing of cyber-information within the

Cybersecurity and Information Sharing: Legal Challenges and Solutions

Nonetheless, DHS’s ability to share federal cyber-intelligence is not limitless. First, cyber-threat

information the government provides to the private sector generally must occur on a voluntary

basis.77 The plain language of Section 223 of the Homeland Security Act limits DHS’s ability to

share cyber-intelligence with “private entities that own or operate critical information systems,”

such that information sharing can only occur “upon [those entities’] request.”78 And indeed, the

NCPA contains an even more explicit provision disclaiming the Act from being “construed to

require any private entity” to request any assistance from the Secretary of DHS.79 In other words,

under current law, DHS generally does not have the authority to “mandate private sector

participation” in federal cyber information sharing efforts,80 leading some to question the value of

the current voluntary information sharing scheme.81

Second, other laws outside of the context of cybersecurity may limit the ability of the government

to disseminate cyber-threat information. The Homeland Security Act itself requires DHS to

ensure that any intelligence in its possession “is protected from unauthorized disclosure and

handled and used only for the performance of official duties.”82 More specifically, the Act

mandates that DHS adhere to (1) the requirements of the National Security Act of 1947 to the

extent any information pertains to intelligence sources and methods and (2) any authorities of the

Attorney General “concerning sensitive law enforcement information.”83 In other words, to the

extent any federal cyber-intelligence contains sensitive information, such as the sources or

methods that are the heart of an ongoing cybercrime investigation,84 the government may be

limited in its ability to disclose such information.

Beyond laws aimed at limiting disclosures that may inhibit core governmental functions, laws

aimed at preserving privacy and civil liberties may also restrict DHS’s ability to share certain

cyber-information. The Homeland Security Act requires DHS to “ensure ... that any information

databases and analytical tools developed and utilized by the Department”—which would

presumably include programs like CISCP and ECS—“treat information in such databases in a

manner that complies with applicable Federal law on privacy.”85 Moreover, the NCPA requires

units.”).

77

The federal government is authorized to provide, without request, “analysis and warnings related to threats to, and

vulnerabilities of, critical information systems” to state and local government entities. See 6 U.S.C. §143(1). Moreover,

the Homeland Security Act authorizes DHS to make general recommendations and disseminate information analyzed

by the Department as “appropriate” or “necessary.” See id. §121(d)(6)-(8).

that the NCCIC “comply with all policies, regulations, and laws that protect the privacy and civil

liberties of United States persons.”86 As such, if DHS’s cyber intelligence included, for example,

individually identifiable information—like a name or a social security number—laws like the

Privacy Act of 1974 may restrict the manner in which the government may disclose such

information in a cyber-information sharing program.87

Collectively, the legal effect of the various federal disclosure and privacy laws may limit the

efficacy of any cyber-information DHS provides private entities. As one commentator recently

noted, the resulting “sanitation” of cyber-intelligence has a dual effect.88 First, the host of federal

agencies that “own classified or law enforcement information germane to a particular warning”

“must be coordinated with as part of the review process,” resulting in significant delays before

DHS can release any information to a private entity, by which time the information may be

irrelevant.89 Second, even if DHS releases government cyber threat information in a timely

manner, the cyber intelligence resulting after agency review of the underlying material may omit

critical information that is “actually useful to industry.”90

Sharing Cyber-Information in the Possession of

Private Entities

Whereas the law governing the dissemination of cyber-threat information in the possession of the

federal government is relatively straightforward, the legal landscape surrounding the sharing of

cyber-intelligence that is in the possession of private parties stands in stark contrast. Indeed, there

is an array of legal concerns—some more theoretical than actual—that shroud the law governing

the sharing of privately-held cyber-threat information in a cloud of uncertainty and create

disincentives against the sharing of such information by private parties.91 The legal issues can be

See 6 U.S.C. §148(e)(3).

87

See 5 U.S.C. §552a(b) (generally prohibiting an agency from disclosing “any record which is contained in a system

of records by any means of communication to any person, or to another agency.... ”). Pursuant to the Privacy Act and

the Homeland Security Act, DHS has promulgated Fair Information Practice Principles (FIPPs), which generally

amount to framework for how the Department uses and disseminates information containing personal identifying

information. See Hugo Teufel III, DHS Privacy Policy Guidance, DEP’T OF HOMELAND SEC., (December 29, 2008),

available at http://www.dhs.gov/xlibrary/assets/privacy/privacy_policyguide_2008-01.pdf. However, it should be noted

that the Privacy Act does contains exemptions for some inter-agency data sharing for national security and law

enforcement purposes, as well as routine uses described by the agency in the Federal Register. See 5 U.S.C.

§§552a(a)(8)(B)(vi), (b)(3), (b)(7), (e)(4)(D), & (j). There are numerous other more narrowly applicable laws on

privacy and data protection that protect specific types of information in the possession of the government that could

implicate the sharing of federal cyber-intelligence. See, e.g., 42 U.S.C. §1320(d) & 45 C.F.R. §§160, 164 (Health

Insurance Portability and Accountability Act of 1996); 18 U.S.C. §1905 (Trade Secrets Act).

Sharing Cyber-Information with Another Private Entity

Information security professionals within the private sector have “long relied” on information

from other private entities to “gain insight into cybersecurity threats and vulnerabilities.”92 And

often the most valuable cyber-intelligence comes from peers in other companies, including direct

competitors that may be subject to similar cybercrimes.93 Private cyber-information sharing can

take many forms, from informal arrangements, such as peer discussions via phone, email, or in

person, to formal sharing arrangements, such as cyber-intelligence sharing through an

Information Sharing and Analysis Center (ISAC), a private sector nonprofit corporation formed to

facilitate the sharing of information on cyber-threats, incidents and vulnerabilities among

members within a particular sector.94 At times, the federal government has been quite supportive

of such private efforts to share cyber-intelligence. Indeed, the impetus for ISACs was Presidential

Decision Directive-63, issued by President Clinton in 1998, which initially called for the creation

of industry-specific ISACs.95 Nonetheless, there are several bodies of law whose basic norms run

counter to the concept of a private business sharing cyber-threat information with an industry

peer, raising potential liability issues for those in the private sector that wish to exchange cyberintelligence.96 Without any overarching federal law governing private exchanges of cyber-threat

information, the potential remains for various laws facially unrelated to cyber-information sharing

to discourage such activity within the private sector.

Privacy Laws

A variety of state and federal privacy laws govern the collection, storage, use, and dissemination

of electronic information, potentially leaving limited room for cyber-intelligence sharing amongst

private actors or between private actors and the government.

The most pertinent federal privacy law is the Electronic Communications Privacy Act of 1986

(ECPA), which contains three titles: (1) Title I, the Wiretap Act,97 which regulates the interception

of communications content in transit; (2) Title II, the Stored Wire and Electronic Communications

and Transactional Records Access Act98 (Stored Communications Act or SCA), which governs

electronic communications already transmitted and currently in storage; and (3) Title III, the Pen

Register and Trap and Traces Devices Act (Pen/Trap Act),99 which regulates the interception of

noncontent communications, such as phone numbers or IP addresses. Each section of ECPA is

potentially relevant to those private entities considering sharing cyber-intelligence information.

The Wiretap Act

The Wiretap Act generally provides for criminal100 and civil damages101 against anyone who

“intentionally intercepts, endeavors to intercept, or procures any other person to intercept or

endeavor to intercept” any covered communication,102 which includes electronic

communication.103 To “intercept” an electronic communication is to use “any electronic,

mechanical, or other device” to acquire the “contents” or the “substance, purport, or meaning” of

the communication,104 contemporaneously with the transmission.105 Relatedly, the statute also

generally prohibits a “person or entity providing electronic communication service to the public”

from intentionally divulging the contents of any electronic communication while in transmission

other than to the “addressee or intended recipient of such communication.”106 Perhaps most

relevant to cyber-information sharing, the Wiretap Act also prohibits the disclosure or use of the

contents of any electronic communication that was obtained in violation of the statute, such an

illegal interception of electronic communications.107

Putting to the side the several exceptions contained in the Wiretap Act, on its face, ECPA’s

general prohibition on the interception of electronic communications would appear to encompass

any strategy for detecting cyber-threats that involved scanning the contents of an electronic

communication while in transmission,108 and ECPA’s general prohibition on an electronic service

99

Id. §§3121-3127.

The Wiretap Act imposes significant criminal penalties on those who violate its terms, with a minimum of a ten

thousand dollar fine per violation and up to five years of imprisonment. See id. §§2511, 2520.

provider divulging the contents of any communication while in transmission may bar the real

time transmission of certain cyber-intelligence.109 While cyber-intelligence may often not include

the contents of an electronic communication and may merely contain, for example, the IP address

of the origin of malware, as one commentator has suggested, many common cyber-threat

detection methods require using the contents of electronic communications—such as text within

the body of an email—to determine whether a particular communication is malicious.110

Moreover, to be effective, cyber-information sharing often necessitates the use of real time

sharing of cyber-threat information.111 Nonetheless, the Wiretap Act contains two key exceptions

to its general prohibition that may limit the scope of the law as it pertains to cyber-information

collection and sharing.112

First, the Wiretap Act includes an exception to its general prohibitions when there is the presence

of consent to the otherwise illicit interception or disclosure (“consent exception”).113 A private

actor can only rely on the consent exception where one of the parties to the communication has

given prior consent to the interception or divulgence.114 Courts reviewing the question of whether

a party to the communication consented to an interception or disclosure will look into the

See generally Shubert v. Metrophone, Inc., 898 F.2d 401, 405 (3d Cir. 1990) (holding that §2511(3)(a) “prohibits a

transmission of that service.”).

110

See Broggi, supra note 31, at 661-62 (“[S]ignatures are comprised of indicators, and ... indicators may include text

strings. If these strings are located in the body or subject line of an email, courts will consider them contents.”).

111

See, e.g., Palmer, supra note 72, at 368 (“The nation needs real-time situational awareness and innovative

cybersecurity standards to keep up with the technological curve of cyber-threats that confront critical infrastructure.”).

112

The Wiretap Act’s prohibition on the use of a “device” to intercept any oral communication, see 18 U.S.C.

§2511(b), contains another exception that may be relevant for those engaged in cyber-threat detection. Specifically,

ECPA’s definition of a “device” necessarily excludes “any device or apparatus” used by “any ... equipment or facility

... furnished to the subscriber or user ... in the ordinary course of business.” See id. §2510(5)(a). However, the “ordinary

course of business” exception may not apply to a private entity that is scanning electronic communication for potential

cyber-threats. Courts have generally interpreted the ordinary course of business exemption to apply to devices that

further an underlying communications system, such as routers or switchboards, which arguably is unrelated to

determining whether particular communications within such a system pose a cyber-threat. See In re Google Inc. Gmail

Litigation, No. 13–MD–02430, 2013 WL 5423918, at *8 (N.D. Cal. September 26, 2013) (holding the “ordinary course

of business exception” “offers protection from liability only where an electronic communication service provider’s

interception facilitates the transmission of the communication at issue or is incidental to the transmission of such

communication. Specifically, the exception would apply here only if the alleged interceptions were an instrumental part

of the transmission of email.”); see also Campbell, 2014 WL 7336475, at *7 (holding the ordinary course of business

exception requires some nexus between interception and the subscriber’s “ultimate business, that is, the ability to

provide the underlying service or good”); see generally Sanders v. Robert Bosch Corp., 38 F.3d 736, 740 (4th Cir.

1994) (refusing to apply the ordinary course of business exemption to a voice logger); Hall v. EarthLink Network, Inc.,

Internet Service Provider was operating in the ordinary course of business by allowing an online advertising company

to conduct technology tests for directing online advertising on electronic communications that the provider ordinary

accessed). More broadly, courts have been reluctant to find that indiscriminate recording of communications is within

the ordinary course of most businesses. See, e.g., United States v. Murdock, 63 F.3d 1391, 1397 (6th Cir. 1995).

purposes of committing any criminal or tortious act in violation of the Constitution or laws of the United States or of

any State.” Id. §2511(2)(d).

“dimensions of the consent” and then ascertain whether the act in question “exceeded those

boundaries.”115

With respect to a private entity’s efforts to collect content-based cyber-threat information and

disseminate such information, the Wiretap Act’s consent exception, while often a viable route to

avoid liability, raises several difficult legal questions. For example, determining who is a “party to

the communication” when someone is launching a cyberattack can be very difficult, as the

cybercriminal may be using multiple computers and the ultimate destination of the hacker’s

communication may be unclear.116 While an entity attempting to monitor its system for cyberintruders could argue that it is a party to the underlying electronic communication being

monitored because the data is flowing on its network and is being directed toward its computers

and employees,117 such an interpretation of what it means to be a party to a communication may

eliminate any privacy protections for the individuals who are directly participating in the

electronic communication.118 Instead, a court may likely interpret that a party to a communication

must be the individuals who actually take part in the electronic conversation.119

Moreover, assuming that the private entity acquiring cyber-threat information is not a party to the

communication, consent must be obtained from one of the individuals taking part in the

communication, which, in turn, depends on the dimensions of the consent and whether the

interception or divulgence of the contents of electronic communication exceeded the boundaries

of the consent.120 Such an inquiry can be quite context specific,121 inviting litigation and creating

legal uncertainty for entities wishing to engage in cyber-information sharing. For example, courts

have come to differing conclusions as to whether an electronic communications service

provider’s customer has consented to having the provider intercept certain communications,

largely because of the specific nature of the interception in question and the precise terms of

service to which the customer agreed.122 Importantly, consent cannot be “casually” inferred,123

and absent actual notice of the nature of the interception or divulgence, consent can only be

implied if the “surrounding circumstances convincingly show that the party knew about and

consented to the interception.”124 Courts, interpreting the consent exception narrowly to ensure

the exemption does not swallow the rule, have held that merely providing a person notice that an

entity has the capability of intercepting communications cannot be considered implied consent.125

And deficient notice will “almost always defeat a claim of consent.”126 As a consequence, for a

private entity that wishes to employ and share the results of a cyber-threat detector, which often is

created with the goal of invisibly tracking communications without alerting either internal or

external users of its operation, notice to a party of an electronic communication that is sufficient

to create consent may, at times, defeat the entire purpose of monitoring and sharing the contents

of electronic communications.

Second, the Wiretap Act also includes a “provider exception” which allows the provider of

electronic communications to “intercept, disclose, or use” the contents of communications when

the activity is a “necessary incident to ... the protection of the rights or property of the provider of

that service.”127 On its face, the provider exception is limited to protecting the “rights or property

of the provider,” as opposed to any third party.128 While at least one court has read the provider

exception broadly to allow a service provider to intercept or disclose covered communications for

purposes of aiding third parties,129 several courts have cabined the provider exception in terms of

whether the interception was done for the purpose of protecting the provider’s own “equipment

and rights.”130 And the Department of Justice’s (DOJ’s) Office of Legal Counsel has likewise

concluded that the provider exception “must protect the provider’s own rights or property, and not

those of any third party.... ”131 As a consequence, there is a strong argument that while ECPA may

authorize private entities to monitor their own system and to share cyber-intelligence necessary to

protect their own system,132 the law likely does not authorize service providers to disclose or

divulge in real time to other private entities or the government133 the contents of electronic

communications for the purpose of protecting a third party’s property or rights.134 In other words,

a more narrow reading of the provider exception may cast doubt on the legality of certain cyberinformation sharing methods.

The Stored Communications Act

In contrast to the Wiretap Act, which focuses on the interception and disclosure of the contents of

communications in transmission, Title II of ECPA—the SCA—is centrally concerned with access

to and the disclosure of both content and non-content based electronic communications that are

kept in storage.135 In relevant part,136 the SCA in Section 2702 generally prohibits service

133

The Wiretap Act does have other means for the government to intercept or receive electronic communications. See,

e.g., 18 U.S.C. §§2516-2518 (authorizing government access to covered communications pursuant to or in anticipation

of a court order); id. §2511(2)(i) (permitting “a person acting under color of law” to “intercept” the contents of “wire or

electronic communications of a computer trespasser transmitted to, through, or from [a] protected computer” under

limited circumstances).

134

See Aaron J. Burstein, Amending the ECPA to Enable a Culture of Cybersecurity Research, 22 HARV. J.L. & TECH.

167, 188 (2008) (“Even if a researcher intercepts electronic communications contents under the provider exception,

disclosing the contents to outside researchers might stretch the requirement of protecting the original service provider’s

rights or property.”) (emphasis added). Moreover, even if a provider, in collecting and sharing cyber-threat information,

is ostensibly acting out of self-interest, courts have been clear that ECPA, by permitting interceptions to “protect the

rights or property” of the provider, does not allow “unlimited” interceptions. See Auler, 539 F.2d at 646 (holding that

the authority of a service provider to intercept and disclose covered communications is “not unlimited”); Councilman,

418 F.3d at 82 (holding that it was “indisputable” that the “narrow[]” provider exception did not exempt a provider who

intercepted and copy all incoming communications to gain a commercial advantage). Instead, there must be a

“substantial nexus” between the monitoring and the threat to the provider’s rights or property. See United States v.

McLaren, 957 F. Supp. 215, 219 (M.D. Fla. 1997). The Department of Justice has interpreted the provider exception to

permit “providers and their agents to conduct reasonable monitoring that balances the providers’ needs to protect their

rights and property with their subscribers’ right to privacy.” See U.S. Dep’t of Justice, supra note 116, at 173. At least

one commentator has suggested that the substantial nexus test may limit the scope of what types of information can be

gathered to combat cyber-threats. See Burstein, supra note 134, at 187 (“Although cybersecurity researchers might ...

provide information that allows their employers to protect their networks, this connection is likely to be highly

attenuated ... since researchers usually develop methods of detecting malicious traffic, their results might not be

immediately applicable to that purpose.”).

135

See 18 U.S.C. §§2701-2702. What sorts of “storage” that the SCA regulates will depend several statutory terms that

will be explained in more detail infra.

136

The SCA also prohibits unauthorized access to an ECS facility and “thereby obtains, alters, or prevents authorized

access to [an] ... electronic communication while it is in electronic storage.... ” See 18 U.S.C. §2701(a). However,

Section 2701 exempts from that general prohibition “conduct authorized ... by the person or entity providing [an] ...

electronic communications service,” see id. §2701(c)(1), meaning that service providers that “obtain” electronic

communication while in storage for the purpose of determining cyber-threats are likely immune from liability under the

first prohibition in the SCA. See Fraser v. Nationwide Mut. Ins. Co., 352 F.3d 107, 115 (3d Cir. 2003) (“[W]e read

providers engaged in either “electronic communications service” (ECS) or remote computing

service (RCS) to the public from divulging the contents137 of communications in their

possessions138 and subjects those that violate the SCA to civil liability.139 Notwithstanding that

general statement about Section 2702, the SCA is a notoriously complicated statute,140 and,

accordingly, Section 2702(a)’s central prohibition regarding the disclosure of the contents of

communications requires some clarification and several caveats.

First, to run afoul of Section 2702(a)(1)-(2)’s prohibition, the entity in question must provide

either ECS or RCS. ECS, as defined under the SCA, includes any service which provides users

the means to “send or receive ... electronic communication,”141 such as businesses that provide

text messaging142 or email143 services. An RCS, as defined by the SCA , entails “the provisions to

the public of computer storage or processing services by means of an electronic communications

system.”144 Courts have interpreted an RCS to refer to the long-term processing or storage of data

by an off-site third party.145 Second, not all disclosures by an ECS or RCS are prohibited by the

SCA; only disclosures of the contents of communications146—as opposed to address information,

like an email address147—would fall within the prohibition. Third, for an ECS provider, only

disclosures made while the underlying communication is in electronic storage amount to a

interpreting “electronic storage” to encompass both electronic messages that have yet to be

delivered to their intended recipient, as well as electronic messages in backup storage by the

provider until “the underlying message has expired in the normal course,”150 while others have

criticized the notion of “electronic storage” encompassing opened emails serviced by an ECS.151

Fourth, for an RCS provider to violate 18 U.S.C. Section 2702(a)(2), the provider must disclose

the contents of communications that are (1) “on behalf of, and received by” a subscriber or

customer of the service; and (2) “solely for the purpose of providing storage or computer

processing services to ... [that] subscriber or customer.”152 The statutory prohibition necessarily

excludes providers of RCS to the public who are authorized to access the contents of

communication for purposes other than for storage and computer processing, such as for

advertising purposes.153

Putting to the side the exceptions to SCA’s prohibition found in 18 U.S.C. Section 2702(a)(1)-(2),

unlike the Wiretap Act, the SCA’s prohibition on disclosing communications in storage will be

unlikely to prohibit many forms of cyber-information sharing. After all, to violate the statute, a

company must not only disclose the contents of communications to another private entity, but the

company doing the disclosure must provide ECS or RCS to the public.154 In other words, if, for

example, an email provider to the public shares the IP address that was the source of a malicious

email to a ISAO, that email provider did not share content information and therefore likely did

not violate the SCA. Moreover, if a private entity provides email services to its employees and

shares the text of an email that is the source of a computer virus with another company, that

private entity likely did not violate the SCA because that entity does not provide ECS or RCS to

the public.

Nonetheless, many Internet Service Providers (ISPs) or email providers ostensibly provide ECS

or RCS to the public,155 and those companies may be interested in sharing the contents of

information with outsiders for cybersecurity purposes. If so, it is uncontroversial to say that

because of disputes over key terms like “electronic storage” and “RCS” and “ECS,” the SCA, as

currently written and interpreted, is hardly a model of clarity.156 The resulting ambiguity about the

legality of information sharing within the SCA’s general ambit may deter providers of ECS or

RCS to the public from sharing cyber-threat information with other private entities.157 After all,

ambiguity in the law often breeds litigation, and the costs of litigation may be significant enough

to deter companies from engaging in cyber-information sharing.158

The hesitancy to participate in information sharing schemes may exist notwithstanding several

exceptions159 to the SCA’s general prohibition on the disclosure of certain types of electronic

communication held in storage.160 For example, while the SCA excludes from its prohibition on

the disclosure of communications disclosures made to a “person employed or authorized ... to

forward such communication to its destination,”161 that exception only eliminates liability for

those entities wishing to gather and share cyber-threat information within that organization162 and

does not sanction the sharing of the contents of a communication with an outsider. Moreover, the

SCA also contains a consent exception, allowing an ECS or RCS provider to divulge the contents

of a communication if the sender or recipient of that communication consents or, in the case of an

RCS, if the subscriber of the communication consents to the disclosure.163 Like the Wiretap Act’s

consent exception, the SCA’s consent exception is largely fact dependent, arguably providing

little assurance to a communications services provider that wishes to wholly eliminate litigation

risk.164 More specifically, the scope of the SCA’s consent exception is directly linked to a service

provider’s status as providing ECS or RCS, which may make the viability of the consent defense

contingent on the murky distinction between when a provider is acting in either role.165 Finally,

similar to the Wiretap Act, the SCA also contains a provider exception, and, much like its

counterpart in the Wiretap Act, the SCA’s provider exception is limited to allowing disclosures

that are necessary for the “protection of the rights or property of the provider”166 and arguably

does not extend to the protection of third parties that the provider may wish to share cyberintelligence.167

Cybersecurity and Information Sharing: Legal Challenges and Solutions

The Pen/Trap Act

The final major federal privacy law potentially relevant to cyber-information sharing amongst

private parties is found in Title III of ECPA, Pen/Trap Act.168 The Pen/Trap Act has been referred

to as the “non-content counterpart” to the Wiretap Act, in that the Pen/Trap Act is concerned with

the real time capturing of non-content information,169 such as IP addresses and the “to” and

“from” fields in an email.170 Specifically, in 18 U.S.C. Section 3121, the Pen/Trap Act generally

prohibits any person from installing or using a “pen register or a trap and trace device,” devices

used outside of the ordinary course of business that capture either incoming or outgoing noncontent electronic information about the source of a communication, without first receiving

permission from a court.171 Violations of the Pen/Trap Act can result in criminal penalties,

including not more than one year in prison.172 Like its counterpart the Wiretap Act, the Pen/Trap

Act, also contains several exceptions to its general prohibition, including a (1) “provider

exception,” which permits service providers to use pen/trap devices for the “operation,

maintenance, and testing of [an] ... electronic communication service” or to protect the “rights

and property” of the provider or the “users of that service from abuse of service or unlawful use

of service,”173 (2) “consent exception,” which allows the use of pen/trap devices where the user of

the service has provided consent.174 Nonetheless, in sharp contrast to the Wiretap Act and the

SCA, the Pen/Trap Act contains no provisions barring the disclosure or divulgence of non-content

information derived from a pen/trap device.175

For a private entity wishing to share non-content cyber-threat information with a third party, the

Pen/Trap Act likely does not raise serious legal concerns. First, the Pen/Trap statute’s provider

exception likely eliminates any potential criminal liability that could arise from a company

168

18 U.S.C. §§3121-3127.

See Burstein, supra note 134, at 191.

170

See Daniel J. Solove, Reconstructing Electronic Surveillance Law, 72 GEO. WASH. L. REV. 1264, 1287 (2004)

(contending that “e-mail headers (the addressing information on e-mail messages), IP addresses, and Uniform Resource

Locators ... fall under [the] definition [of information captured by a pen/trap device].”); see also Dep’t of Justice, supra

note 116, at 154 (“Because Internet headers contain both ‘to’ and ‘from’ information, a device that reads the entire

header ... is both a pen register and trap and trace device.... ”).

171

18 U.S.C. §3121(a). Specifically, in relevant part, the Pen/Trap statute defines a “pen register” as a device that

records or captures information that is “reasonably likely to identify the source of [an] ... electronic communication,”

see id. §3127(3), whereas a “trap and trace device” is defined as one that captures incoming electronic or other

impulses that “identify the originating number or other dialing, routing, addressing, and signaling information

reasonably likely to identify the source of [an] ... electronic communication,” id. §3127(4). Both definitions exclude

devices that capture content information, id.§3127(3)-(4), and the definition for a pen register excludes “any device ...

used by a provider or customer of [an] ... electronic communication service for billing, or recording as an incident to

billing ... or any device ... used ... for cost accounting or other like purposes in the ordinary course of business,”

id.§3127(4).

172

See id.§3121(d).

173

18 U.S.C. §3121(b)(1).

174

Id. §3121(b)(3). The government can obtain authority to install a pen/trap device by certifying to a court “that the

information likely to be obtained [from a pen register] is relevant to an ongoing criminal investigation” being

conducted by a law enforcement agency. See 18 U.S.C. §3122(b).

175

Cf. United States v. Reed, 575 F.3d 900, 914 (9th Cir. 2009) (concluding that the Pen/Trap Act contains no

requirement that non-content information form a pen/trap device be sealed from public disclosure); see Burstein, supra

note 134, at 192 (“The Pen/Trap statute’s exception, however, si concerned only with the condition for allowing a

service provider to install a pen register; the statute lacks a corresponding disclosure provision.”); see also Broggi,

supra note 31, at 672 (“Unlike the Wiretap Act however, the statute is silent regarding voluntary disclosure of

information obtained under these exceptions.”).

169

Cybersecurity and Information Sharing: Legal Challenges and Solutions

monitoring and capturing non-content information for cybersecurity purposes. After all, the

Pen/Trap Act’s provider exception sweeps more broadly than the provider exceptions in the

Wiretap Act or the SCA, in that Title III of ECPA allows providers to use a pen/trap device

“relating to the operation, maintenance, and testing of [an] ... electronic communication system....

”176 Given that nearly any electronic communication system, such as email or Internet

communication, necessarily depends on routing information from one source to another,177 it is

arguable that most private entities with genuine cybersecurity concerns may likely be capturing

non-content information as a natural product of the operating of an electronic communication

system anyway.178

Moreover, even if an entity’s decision to capture non-content address information is not related to

the “operation, maintenance, and testing of [an] ... electronic communication system,” the second

clause of the Pen/Trap Act’s provider exception allows the use of a pen/trap device to protect the

rights or property of the provider or the users of the service from “abuse of service or unlawful

use of service,”179 which would appear to encompass the circumstance where a private entity

collects non-content information to identify the source of a potential cyber-threat.180 In addition,

even if the provider exception does not allow the use of a pen/trap device, the consent exception

would allow a provider to capture non-content cyber-threat information with the agreement of the

provider’s user.181 Importantly, because the Pen/Trap Act only criminalizes the illegal use of

pen/trap devices and does not regulate the disclosures of non-content information culled from a

pen/trap device, once a provider has legally used a pen/trap device, there appears to be no reason

why a private entity should fear liability under the Pen/Trap Act if a company were, for example,

to share the IP address that was the source of malware with another private company.182

Other Federal and State Privacy Laws

While ECPA is the most prominently mentioned federal privacy law that could implicate cyberthreat information sharing efforts, other federal privacy laws could also plausibly deter the

exchange of cyber-intelligence amongst private entities. As noted above, ECPA’s privacy

protections are tied to (1) the age of the underlying communication, with communications in

storage generally getting less protection than communications that are being transferred in real

time, and (2) whether the underlying communication reveals substantive content, with noncontent information, such as IP addresses and email addresses, receiving fewer protections under

the statute.183 In contrast to ECPA, a host of various federal privacy laws target specific industries

176

18 U.S.C. §3121(b)(1).

See David D. Clark and Susan Landau, Untangling Attribution, 2 HARV. NAT’L SEC. J. 531, 534-35 (2011)

(describing all “data transport service of the Internet” as being based on packets, “small units of data prefixed with

delivery instructions.”).

178

See Columbia Pictures Industries v. Bunnell, No. 06-1093FMCJCX, 2007 WL 2080419, at *11 (C.D. Cal. May, 29,

2007 (holding that the capturing of an IP address necessary to “operate [a] website” falls within the Pen/Trap Act’s

provider exception).

181

182

There could be an argument that sharing non-content information with the government raises liability issues under

the SCA. See infra “Privacy Concerns.” Nonetheless, neither the SCA nor the Pen/Trap Act provide for criminal or

civil liability when a private entity discloses non-content information to another private entity.

that tend to control personally identifying information (PII), such as names, addresses, phone

numbers, or Social Security numbers. For example, the Cable Communications Policy Act of

1984 (CCPA) generally prohibits “cable operators”184 from collecting and disclosing PII,185

subjecting entities that violate the CCPA’s privacy protections to civil liability.186 Some courts,

interpreting the CCPA, have concluded that cable providers when providing Internet services can

be subject to the Act’s privacy provisions,187 raising the specter of civil liability if a cable ISP

were to disclose PII—like a name or an email address—while sharing cyber-threat information

with another private entity.

Much as the CCPA could raise liability concerns for cable ISPs wishing to share cyberinformation with other private entities, so too could a variety of federal privacy laws raise legal

questions for the entities that are regulated by such laws. Indeed, several discrete federal privacy

laws regulate how PII is collected and disseminated. These laws target a variety of distinct

entities, including

any person or group of persons (A) who provides cable service over a cable system and directly or

list of names and addresses on which the subscriber is included.... ” See Scofield v. Telecable of Overland Park, Inc.,

973 F.2d 874, 876 n. 2 (10th Cir.1992). Another court has held that a person’s name, address, and telephone are

included in term “personal identifiable information.” See Warner v. Am. Cablevision of Kansas City, Inc. ., 699

other information regarding the customer.”). There are several exceptions to the CCPA’s general prohibition on

collecting or disclosing PII, including a consent exception, see 47 U.S.C. §551(b)(1) & (c)(1), an exception based on

the need to conduct a “legitimate business activity,” id. §551(b)(2) & (c)(2), and an exception for disclosure to the

To the extent any one of these entities wishes to share cyber-intelligence within its possession

with others in the private sector, legal questions may abound if any of the information to be

shared contains material that is potentially protected under federal privacy law. None of the

aforementioned federal privacy laws specifically contemplate any exceptions for the sharing of

cyber-information for cybersecurity purposes. And, there is very little, if any, case law examining

how a given law applies to the specific context of the collection and dissemination of information

for cybersecurity purposes, leaving a legal lacuna for those regulated entities that may wish to

engage in cyber-information sharing.

Beyond federal privacy laws, states and localities have enacted countless laws that may prevent

or deter private entities from sharing cyber-intelligence with others. All but one of the fifty states

has an eavesdropping law that is generally modeled off the Wiretap Act,195 and a majority of

states regulate the collection and dissemination of electronic communications.196 While many of

the state communications privacy laws mirror federal law, state laws are often more restrictive or

may simply regulate different aspects of communications privacy than federal law,197 multiplying

the legal questions facing those entities wishing to engage in cyber-information sharing. For

example, eight states currently generally require both parties to an electronic communication to

consent to its interception and/or further dissemination,198 allowing, in the words of one

commentator, cyber “attackers a veto on whether their packets are inspected for malicious

code”199 and potentially deterring some entities from collecting and divulging cyber-threat

information to others.

Moreover, much like the federal government, some states have laws that target the collection and

divulgence of PII within the possession of entities that may wish to engage in cyber-information

sharing.200 Although an examination of the various state privacy laws is beyond the scope of this

report, these laws may raise liability concerns for entities that do business in multiple states and

wish to disseminate cyber-threat information outside of the company.

Antitrust Laws

In addition to federal and state privacy laws, antitrust laws also have generated liability concerns

for private entities that wish to collaborate over cybersecurity.201 Indeed, in a recent survey, more

than a quarter of IT professionals identified “anti-competitive concerns” as one of the central

reasons for not participating in information sharing programs.202 Deterring anticompetitive

conduct by businesses, such as coordinated action that undermines competition, is at the heart of

federal antitrust law.203 Specifically, the Supreme Court in interpreting the Sherman Antitrust

Act—the “primary federal antitrust enforcement mechanism”204—has recognized that the law’s

facial prohibition in Section 1 on all contracts, combinations, or conspiracies that result in a

restraint of trade or commerce205 should be read to prohibit only those agreements that

unreasonably restrain trade.206 While courts interpreting the reach of the Sherman Act generally

view any concerted activity with some degree of skepticism,207 certain agreements, such as price

fixing and market allocation among competitors, are viewed as being so “inherently

anticompetitive that each is illegal per se without inquiry into the harm it has actually caused.”208

Other agreements, such as mergers or joint ventures that may facilitate more effective

competition, are adjudged under the “rule of reason,” in which a court will weigh the legitimate

justifications for a restraint against any anticompetitive effects.209 In other words, determining

whether a given agreement between two private businesses violates the Sherman Act largely

depends upon the specifics of that particular agreement.210 Businesses that are alleged to violate

federal antitrust laws face potential criminal prosecutions,211 as well as civil actions that could be

initiated by the federal government,212 state governments,213 or even aggrieved private litigants.214

Civil litigation risks treble damages—damages three times the amount of actual damage—being

paid to successful plaintiffs.215

While fears abound that any coordination on cyber-defense could give rise to antitrust liability,216

the likelihood of such liability will likely depend on the nature and purpose of the underlying

agreement to share cyber-threat information.217 Exchanges of information among competitors do

not constitute per se violations of the Sherman Act, as the Supreme Court has found that such

practices can “increase economic efficiency and render markets more ... competitive.”218

Moreover, the Court has been reluctant “to condemn rules adopted by professional associations as

unreasonable per se.... ”219 As a consequence, perhaps a few agreements to coordinate on cyberdefense—such as an agreement amongst competitors to “implement a uniform set of cyber-

security practices”220 by either agreeing to “pass on” certain associated costs to customers221 or

adopt cybersecurity practices that provide inferior products to end users222—may “amount to a

‘naked’ restraint that results in reflexive condemnation under the per se rule.”223 Nonetheless,

most efforts to share cybersecurity information amongst private entities, particularly within a

formal organization like an ISAC, will likely be adjudged under the rule of reason.224 A rule of

reason analysis would weigh the legitimate justifications for engaging in concerted efforts to

share cyber-information against any anticompetitive effects.225 As such, a rule of reason analysis

regarding cyber-information sharing may weigh the interest in combatting fraudulent cyberactivity226 versus the potentiality of certain actors being excluded from the cyber information

forum for anticompetitive reasons.227 Nonetheless, there is no case law that squarely addresses

how antitrust laws apply to coordinated efforts to combat cyber-threats, and given the central role

of common law in defining the limits of federal antitrust law, the net result may be considerable

legal uncertainty for those private entities that may wish to engage in such activities.

Recognizing the legal uncertainty that exists with respect to antitrust law and cybersecurity

information sharing, in April of 2014, DOJ and the Federal Trade Commission (FTC) issued a

joint policy statement that attempted to clarify the extent to which the exchange of cyber-threat

information amongst private parties could raise antitrust issues.228 The joint policy statement

confirmed that information sharing agreements are typically examined under a rule of reason

analysis,229 and the statement continued by recognizing that the exchange of cyber-threat

information has numerous positive effects that will weigh in favor of its legality, including

helping “secure our nation’s networks of information and resources.”230 Moreover, the joint

policy statement emphasized that the typical nature of cyber-threat information—described as

being “very technical in nature”—is often unlikely to contain “competitively sensitive

information” that would allow participants to “raise prices or reduce output, quality, service, or

innovation.”231 Instead, the two agencies underscored that the primary antitrust concern in the

context of cyber information sharing is the sharing competitively sensitive information, such as

“current, and future prices, cost data, or output levels” that could allow for “competitive

coordination among competitors.”232

Notwithstanding the value of the joint guidance, as the guidance concedes, any analysis of the

legality of a cyber-information sharing agreement is “intensely fact-driven,”233 and, given the

predominant role of the rule of reason with respect to examining the legality of any cyber-threat

sharing agreements,234 definitive conclusions by the government about the legality of

cybersecurity information sharing arrangements vis-à-vis antitrust law may simply be

impossible.235 Moreover, given the role of private parties in enforcing federal antitrust law

through civil lawsuits,236 even if government entities like the FTC and the DOJ generally agreed

that antitrust laws should not be enforced with respect to concerted actions over cybersecurity,

nothing prevents an aggrieved private party from initiating an antitrust lawsuit to prevent

collaboration over cyber-information sharing,237 meaning that without a change in the current law

liability risks from antitrust suits may remain for any private entity interested in sharing

cybersecurity information.

Tort Law

Another often-cited source of liability that may dissuade private entities from participating in

cyber-information sharing schemes is tort law, specifically torts founded upon negligence– that is,

the fear that by sharing and obtaining cyber-information a private entity may be liable for

negligently failing to act upon certain threat information.238 Generally under tort law, to establish

that a defendant has acted negligently, a plaintiff must show: (1) a duty of care owed to the

plaintiff by the defendant; (2) a breach of that duty by the defendant; (3) causation (i.e., the

resulting injury was both the “but for” and “proximate cause or foreseeable consequence of the

risk created by the defendant’s act or omission”); and (4) a cognizable injury or harm to the

plaintiff.239 In the context of a lawsuit following a cyberattack, an injured party may seek

235

The DOJ has developed a business review procedure, whereby groups can submit a specific plan to collaborate on

cybersecurity efforts to the Justice Department for a determination by the agency of whether the proposed collaboration

would raise antitrust concerns. See 28 C.F.R. §50.6; see, e.g., Letter from Joel I. Klein, Assistant Attorney General,

Dep’t of Justice, Antitrust Div., to Barbara Greenspan, Assoc. Gen. Counsel, Elec. Power Research Inst., Inc. (October

15 U.S.C. §15(a).

237

In order to succeed on such a claim, in addition to demonstrating a violation of federal antitrust law, a private party

would have demonstrate an “antitrust injury”—i.e., that it possesses “antitrust standing”—which requires a showing

that the plaintiff was harmed by the defendant’s anticompetitive contract combination, or conspiracy, and that harm

flowed from an “anti-competitive aspect of the practice under scrutiny.” Atl. Richfield Co. v. USA Petroleum Co., 495

U.S. 328, 334 (1990).

compensation from a company whose network was breached, arguing that the company owed its

customers a duty of reasonable security to protect against cybercriminals stealing their data.240

However, while courts have generally recognized that “cyber attacks are [a] foreseeable” risk for

which a service provider must account,241 courts have been fairly reluctant to find that a

particular cyberattack should have been anticipated by a service provider.242 After all, just as a

business has no duty to protect its customers against unforeseeable crimes from third parties,243 so

too must the “duty to implement security thwarting third-party cybercrimes ... turn on whether the

crime was foreseeable.”244 In other words, under tort law, a business likely does not have a duty to

guard against “innovative [cyber-]breaches that have no known or effective defense at the time of

the attack.”245

Because tort liability for a cyberattack will likely turn on the amount of knowledge a given party

may have about a cyberattack, cyber-information sharing schemes have the potential to change

the tort liability calculus for those entities that participate. For example, if a company opts to

share information about the origins of a recent cyberattack perpetrated on that company with a

public information sharing group, like an ISAC, the company may be admitting that it could have

foreseen the attack or mitigated its effects in some way, providing potential plaintiffs with

credible evidence to support a potential tort lawsuit. Likewise, entities that receive information

about a potential cyberattack, fail to act, and then subsequently are targeted by the attack, can no

longer credibly claim that the harm from the cyberattack was unforeseeable. In this sense, tort law

can have the perverse effect of incentivizing private entities to “simply stay[] in the dark” about

potential cyberattacks and to not participate in cyber-information sharing programs.246

Nonetheless, even if participation in a cyber-information sharing agreement increases tort liability

risks, it remains very difficult for a plaintiff to succeed on the theory that a private entity failed to

prevent a cyberattack. First, in order for cyber-threat sharing to increase tort liability risks, an

entity would have to have some considerable bad luck. The company in question would not only

have to suffer a cyberattack, but that cyberattack would have to be linked to a cyberattack in

which information was shared about, and the cyberattack would have to result in actual damages

for a plaintiff. Notwithstanding popular media accounts regarding potential losses created by a

cyberattack,247 most of the cost of a cyberattack will be borne by the company attacked and will

not result in actual losses for potential plaintiffs in a tort lawsuit, like a customer.248 And courts

have been loath to allow a lawsuit to proceed based on the potential for future injury resulting

from a cyberattack.249 Second, and perhaps most importantly, the economic loss doctrine—which

prohibits parties from recovering financial losses, absent injury to person or property, under tort

law250—often prevents recovery in a lawsuit respecting a cyberattack because “[m]any of the

harms that would result from a cyber-attack on, say, the power grid or the financial sector would

be purely economic in nature.”251 And indeed, in recent tort lawsuits regarding cyberattacks,

courts have dismissed tort claims at early stages of the litigation because of the economic loss

doctrine.252 In short, the litigation risks posed by tort lawsuits respecting a cyberattack may be

fairly minimal regardless of whether an entity is involved in cybersecurity sharing.253

247

253

The Bipartisan Policy Center has hypothesized that “domain names and companies who host websites” that may be

the subject of cyber-threat information may sue “entities that collect and aggregate cyber-threat information,” like

ISACs, regarding the “accuracy of their data,” potentially chilling cyber-information sharing. See Bipartisan Policy

Center, supra note 30, at 9-10. Presumably such a lawsuit would be based on a defamation claim—that is, an allegation

that a defendant negligently published an unprivileged, false, and defamatory statement to a third party. See

RESTATEMENT (SECOND) OF TORTS §558. The study from the Bipartisan Policy Center does not cite to any lawsuits that

have been filed against a cyber-information sharing organization or any other accounts of such an organization being

threatened with a lawsuit for the publication of cyber-threat information, making it difficult to assess whether such

lawsuits have actually chilled information sharing efforts. See Bipartisan Policy Center, supra note 30, at 9-10.

Nonetheless, Congress, in the Communications Decency Act (CDA), has already provided immunity to defamation

lawsuits directed at services that provide information to multiple users by giving them access to a computer server. See

47 U.S.C. §230(c)(1). Courts interpreting the CDA have generally agreed that the Act immunizes online information

hosts from liability for defamatory material posted through their services by third parties. See, e.g., Zeran v. Am.

Online, Inc., 129 F.3d 327, 330 (4th Cir. 1997); Green v. America Online, 318 F.3d 465, 471 (3d Cir. 2003); Universal

Zuckerberg, 753 F.3d 1354, 1359 (D.C. Cir. 2014). So long as a cyber-information sharing service is not “creating or

developing” cyber-threat information and sharing it with other entities, see Fair Hous. Council of San Fernando Valley,

489 F.3d at 925, it appears the CDA likely shields such entities from any defamation lawsuits that could potentially

chill broader cyber-information sharing efforts.

Cybersecurity and Information Sharing: Legal Challenges and Solutions

Other Sources of Liability

Beyond privacy, antitrust, and negligent tort law, several other laws could be the source of

liability concerns for private entities that choose to share cyber-information with each other. For

example, the 2013 Target data breach incident led to a shareholder derivative suit against Target’s

officers and board of directors, that alleged that those actors violated fiduciary obligations of

trust, loyalty, good faith, and due care by failing to take adequate steps to prevent the cyberattack

and by making inaccurate disclosures to their shareholders about the extent of the damage from

the attack.254 Shared cyber-information could be critical evidence in a similar suit. If, for example,

a company that suffered a data breach like Target shared cyber-threat information with an ISAC

prior to the attack, one could imagine such evidence being used in a similar shareholder lawsuit to

establish that the company’s officers had specific knowledge about the company’s cybervulnerabilities or the extent of a cyber-attack on a given day.

And a shareholder derivative lawsuit is only one genre of litigation that could both result from a

cyberattack and be aided by shared cyber-information.255 For example, institutional customers

who sue a bank in the wake of a cyberattack that has resulted in fraudulent wire transfers could be

helped by evidence that a bank knew about particular risks posed by a cyberattack. The general

framework governing the rights and obligations between a bank and customers respecting

fraudulent wire transfers is found in Article 4A of the Uniform Commercial Code (UCC).256

Article 4A generally requires banks to bear the risk if a third party steals a customer’s identity,

resulting in a fraudulent wire transfer.257 Nonetheless, the UCC contains an exception whereby a

customer will bear the risk of a fraudulent payment order if: (1) a bank and its customer agree to

implement a security procedure designed to protect against fraud; (2) the security procedure that

is implemented is a “commercially reasonable” method of providing security against

unauthorized payment orders; and (3) the bank demonstrates that it accepted the payment order in

good faith and in compliance with the security procedure.258 While the question of whether a

particular security procedure can be deemed “commercially reasonable” will likely depend on the

specific facts surrounding a cyberattack and the procedures a bank had in place to prevent such a

fraudulent transfer,259 one critical factor may be a bank’s prior awareness of the risks posed by a

cyberattack.260 In this vein, knowledge that a bank knew about a cybersecurity risk because of

shared cyber intelligence could implicate that bank’s liability with regard to a suit under the UCC.

Even in the context of securities litigation, in addition to state common law breach of fiduciary duty claims, federal

law allows a private actor to sue as a result of a material misstatement or omission in connection with the purchase or

sale of any security, see Halliburton Co. v. Erica P. John Fund, Inc., 134 S. Ct. 2398, 2407 (2014), which could

plausibly include a claim for failing to disclose cybersecurity risks to investors or federal regulators, see infra notes

Cybersecurity and Information Sharing: Legal Challenges and Solutions

More broadly, there are “a myriad of legal theories, including ... breach of express or implied

contract, state deceptive trade practices act violations or state data breach notification violations”

that could be the basis for a lawsuit against an entity that suffered a data breach.261 Shared cyberinformation could be critical evidence that helps prove, for example, the timing of when a

cyberattack occurred or the company’s knowledge of the attack and the sufficiency of the

company’s cyber-defenses at the time of the breach,262 which could result in private entities being

less likely to share cyber-intelligence with any other entity or organization.

Sharing Cyber -Information with the Government

Just as private entities are increasingly recognizing the need to access cyber-intelligence gathered

by their peers,263 the federal government may need access to cyber-threat information in the

possession of the private sector in order to make informed decisions about the government’s and

the nation’s cybersecurity needs. As Lisa Monaco, the President’s Homeland Security Advisor,

recently noted, the “private sector has vital information we don’t always see unless they share it

with us.”264 Nonetheless, obtaining cyber-intelligence from the private sector can be difficult for

the federal government. Putting aside the difficult issues that may arise when a private party

affirmatively refuses to divulge cyber-intelligence within its possession to the federal government

and the government is forced to obtain, for example, a warrant or a subpoena to access such

information,265 the federal government may not know that a private entity possesses certain cyberintelligence, and the only way the government can learn about a potential cyber-threat is by

having the private party voluntarily share that information with the government. The voluntary

disclosure of cyber-intelligence to the government may, however, be something private parties are

reluctant to do because of various legal concerns.

Before discussing those legal concerns, it is important to note from the onset that the government,

and specifically DHS, has ample legal authority to receive voluntarily266 shared cyberinformation. For example, under Section 201 of the Homeland Security Act, the I&A is

authorized to “receive ... information ... [from] private sector entities ... in support of the mission

responsibilities of” DHS.267 Moreover, the NCPA provided explicit statutory authority for the

NCCIC to serve as an “interface for the multi-directional ... sharing of information related to

cybersecurity risks, incidents, analysis, and warnings.... ”268 More broadly, the Critical

Cybersecurity and Information Sharing: Legal Challenges and Solutions

Infrastructure Information Act (CIIA), a subtitle within the Homeland Security Act, has extensive

provisions regarding the treatment of “critical infrastructure information” that is “voluntarily

submitted to a ... federal agency”,269 reflecting an assumption that the federal government is not

precluded from receiving from a private entity voluntarily shared information pertaining to

critical infrastructure.270

Freedom of Information Act Disclosures

One central concern for those private entities that may wish to share cyber-intelligence with the

government is that the information shared, which may include proprietary information or even

simply embarrassing material,271 could be disclosed through the Freedom of Information Act

(FOIA), whether through an affirmative agency disclosure or through a public request.272 FOIA

generally provides that government agencies “shall make available to the public” certain agency

records, except insofar as the records are protected from disclosure under several exemptions to

the Act.273 Congress, in the CIIA, provided an exemption to FOIA for any “critical infrastructure

information” (CII)274 that is “voluntarily submitted” to DHS275 for us
