Washington, D.C., April 26, 2013 โ Since at least 1997, the National Security Agency (NSA) has been responsible for developing ways to attack hostile computer networks as part of the growing field of Information Warfare (IW), according to a recently declassified internal NSA publication posted today by the non-governmental National Security Archive (“the Archive”) at The George Washington University. Declaring that “the future of warfare is warfare in cyberspace,” a former NSA official describes the new activity as “sure to be a catalyst for major change” at the super-secret agency.
The document is one of 98 items the Archive is posting today that provide wide-ranging background on the nature and scope of U.S. cyber activities.
Activities in cyberspace โ both defensive and offensive โ have become a subject of increasing media and government attention over the last decade, although usually the focus has been on foreign attacks against the United States, most notably the Chinese government’s reported exploitation of U.S. government, commercial and media computer networks. At the same time, the apparent U.S.-Israeli created Stuxnet worm, designed to damage Iranian centrifuges, has put the spotlight on the United States’ own clandestine cyber efforts.
The NSA’s new assignment as of 1997, known as Computer Network Attack (CNA), comprises “operations to disrupt, deny, degrade or destroy” information in target computers or networks, “or the computers and networks themselves,” according to the NSA document.
Today’s posting by the Archive highlights various aspects of U.S. cyberspace activities and concerns going back to the late 1970s. The documents โ obtained from government and private websites as well as Freedom of Information Act requests โ originate from a wide variety of organizations. These include the White House and National Security Council, the National Security Agency, the Departments of Defense, Energy, and Homeland Security, the military services, the General Accounting/ Government Accountability Office, and the Congressional Research Service โ as well as three private organizations (Project 2049, Mandiant Corporation, and Symantec).

Among the highlights of the documents are:
The NSA’s earlier concerns about the vulnerability of sensitive computer systems to either viruses or compromise through foreign intelligence service recruitment of computer personnel (Document 1, Document 2, Document 3, Document 4, Document 9)
The Secretary of Defense’s March 1997 authorization of the National Security Agency to conduct computer network attack operations (Document 11)
Detailed discussions of Chinese computer network exploitation activities (Document 66, Document 79, Document 83)
Analyses of the Stuxnet worm (Document 40, Document 42, Document 44, Document 88)

Cyberspace and U.S. National Security
By Jeffrey T. Richelson
In an October 2012 speech (Document 78), then-Secretary of Defense Leon Panetta told a group of business executives that “a cyber attack perpetrated by nation states [or] violent extremist groups could be as destructive as the terrorist attack on 9/11,” and raised the prospect of a “cyber Pearl Harbor.” In his February 2013 State of the Union address, President Barack Obama asserted that “our enemies are … seeking the ability to sabotage our power grid, our financial institutions, our air traffic control systems.” Later that month, Director of National Intelligence James R. Clapper led off his annual threat assessment (Document 90) appearance before the Senate Select Committee on Intelligence with a discussion of the Intelligence Community’s assessment of the cyber threat.1

Concern about the potential damage of cyber attack did not originate in the current administration. Even before the establishment of the computer connectivity of the current Internet-era, there was concern, including in the National Security Agency, about the threat of computer viruses (Document 1, Document 2, Document 3, Document 4, Document 5, Document 6) or the vulnerability of computer systems due to recruitment efforts by hostile intelligence services (Document 9). More recently, the William J. Clinton and George W. Bush administrations focused on the connection between cyberspace and national security, issued policy directives, and considered and/or authorized both public and covert actions.
Occasionally, some of those concerns have been met with skepticism. Critiques have included the assertion that the very structure of the Internet means it is not subject to a ‘Pearl Harbor’ type attack โ that is, an attack at single point. The association of power outages in the northeastern United States in 2003 and Brazil in 2007 with cyberattacks has been challenged by reviewers and experts โ who point to studies that concluded there were other, more mundane, causes. One writer has asserted that cyberwar is not here, and that it is not coming. Additional issues that have been raised include the lack of disclosed evidence with regard to more extreme claims concerning the threat, the dangers of threat inflation (including facilitating the expenditure on ‘cyber pork’), and the extent to which the costs of other types of criminal activity (such as car theft) dwarf the cost of cyber crime.2 What is indisputable, however, is the dramatic increase in attention โ both in the U.S. Government and private industry โ to activities in cyberspace in the last decade โ which has been reflected in both media coverage and the release of private and government documents.
Attacks & Exercises
Source: Defense Science Board. See Document 81.
Significant attention has been devoted, in both the classified and unclassified realms, to actual attacks as well as exercises that have sought to determine the vulnerability of key government and infrastructure systems to attack.
The Government Accounting Office (renamed the Government Accountability Office in 2004) reported (Document 6) that between April 1990 and May 1991, a period that encompassed Operations Desert Shield and Desert Storm, computer hackers from the Netherlands penetrated 34 Department of Defense sites. According to that report, the hackers were able to access “unclassified, sensitive information” concerning military personnel, logistics, and weapons systems development. The report also asserted that, particularly during times of international conflict, “such information … can be highly sensitive.”
In March and April 1994, according to GAO reports (Document 10a, Document 10b), the Air Force’s Rome Laboratory, in upstate New York, was targeted by a pair of hackers (a 16-year old British student and a 22-year old Israeli technician) who, using “Trojan Horse” and “sniffer” programs, managed to take control of the lab’s networks. In addition to taking all of the lab’s 33 subnetworks offline for several days, the hackers also stole air tasking order research data and gained access to systems at NASA’s Goddard Space Flight Center, Wright Patterson Air Force Base, and a variety of defense contractors.

In February 1998, several Department of Defense networks were attacked through a commonly understood vulnerability in the Solaris (UNIX-based) computer system โ the investigation of which was designated SOLAR SUNRISE. The attack involved probing Defense Department servers to determine if the vulnerability existed, and then exploiting it โ entering the system and planting a program to collect data. The hackers, ultimately discovered to be two California high school students, also mounted at least a second intrusion to extract data from the penetrated computers.3
In 2003, a series of computer intrusions were directed against the U.S. Defense Information Systems Agency (DISA), the U.S. Redstone Arsenal, the Army Space and Strategic Defense Command, and several DoD contractors – but they apparently went undetected for several months. That series of intrusions was labeled TITAN RAIN, and Defense Department investigators believed it to have originated in China. In June 2006, Department of Energy officials acknowledged that the names of and personal information of more than 1,500 National Nuclear Security Administration (NNSA) employees had been stolen due to network intrusion that apparently began in 2004.4
Another set of attacks that attracted attention (Document 27) was directed against former Soviet-controlled territories, and was widely believed to have been the work of the Russian government. On July 20, 2008, the Georgian president’s website was subjected to a denial-of-service attack. On August 8, a coordinated, distributed denial-of-service attack occurred on other Georgian government websites. At that time, Russian forces were engaged in combat with Georgian forces. Additional cyber attacks on Lithuanian and Kyrgzstan targets took place in June 2008 and January 2009, respectively. The attack on Lithuanian websites occurred three days after that country passed legislation outlawing the use of Soviet and communist symbols, while the January 2009 attack took place on the same day that Russia tried to pressure Kyrgyzstan to revoke U.S. access to the Bishkek airbase being used as a transit point for supplies to Afghanistan.5
Since that time there have been numerous reports of cyber incidents. Included have been a series of attacks on global energy targets, dubbed NIGHT DRAGON, a 2012 cyber attack on the Saudi Arabian state-owned Aramco oil company, and cyber attacks on U.S. banks and companies โ attacks alleged to have been the responsibility of Iran.6
Along with the actual intrusions that have been taking place for over two decades, the United States has also conducted a number of exercises and studies in an attempt to assess the extent of computer network vulnerability. The first exercise, designated ELIGIBLE RECEIVER, was conducted over 90 days in 1997, and involved a Red Team consisting of 35 individuals. Simulated, and apparently successful, cyber attacks were made against government and private power and communications networks in Oahu, Los Angeles, Colorado Springs, St. Louis, Chicago, Detroit, Washington, D.C., Fayetteville, and Tampa. The head of the Pentagon’s Joint Task Force – Computer Network Defense, wrote that the exercise “clearly demonstrated our lack of preparation for a coordinated cyber and physical attack on our critical military and civilian infrastucture.”7
A subsequent exercise, designated LIVEWIRE, was conducted by the Department of Homeland Security. In 2005, the CIA’s Information Operations Center conducted a three-day exercise, codenamed SILENT HORIZON. The objective of the exercise was to practice defending against a cyber attack that would be on the same scale as the September 11, 2001, events, and would target both governmental and private sectors.8
Intelligence and Threat Assessments
Intelligence/threat assessments concerning cyberspace include estimates of the current and projected future cyber capabilities and activities of a variety of nations and groups. They can also include assessments of the specific threats faced by government and private organizations in relation to the current state of cyber security.
In late 2012 and early 2013, several press sources reported that a national intelligence estimate focused on worldwide cyber activities had either been completed or was in the process of completion. An earlier estimate was produced in February 2004: NIE-2004-01D/I, Cyber Threats to the Information Infrastructure. An additional national intelligence product was produced for the Office of the Director of National Intelligence (ODNI) by the Intelligence Science Board – a January 2008 report titled Technical Challenges of the National Cyber Initiative. 9
None of those products has been released, even in redacted form. Estimates and assessments which have been released include those produced by the Congressional Research Service, the Defense Security Service, a ODNI component, and a contractor for the U.S.-China Security and Economic Review Commission. In 2007, the CRS examined (Document 24), inter alia, examples of vulnerabilities that terrorists might decide to exploit in attempting a coordinated cyberattack and ways that terrorists might be improving their cyber skills. The report, Terrorist Capabilities for Cyberattack: Overview and Policy Issues, noted different views concerning the ability of Al-Qaeda (or other terrorist groups) to launch a significant cyberattack and the related danger of a “Digital Pearl Harbor.” It also noted a CIA assessment, provided in April 2002 to the Senate Select Committee on Intelligence, that “cyberwarfare attacks against the U.S. critical infrastructure will become a viable option for terrorists as they become more familiar with the technology required for the attacks.”
A 2004 assessment of the intelligence threat (Document 18), particularly from nations or others seeking to conduct economic espionage was produced by the Interagency OPSEC Support Staff. One chapter focuses on ‘Computers and the Internet’. In addition to providing a history of Internet security and discussing the relationship between website content and operational security, it also explores the roots of network vulnerability and eight outsider attack techniques – including scanning, packet sniffing, and malware.
Several unclassified assessments (Document 26, Document 43, Document 63) by the Defense Security Service have focused on foreign attempts to acquire advanced U.S. technology. The most recent version (Document 63), as with previous versions, examines a variety of methods for acquiring information on U.S. technologies โ including “suspicious network activity,” which was the most prevalent collection method for “entities originating from East Asia and the Pacific.”
A similar type of assessment (Document 55) was produced in October 2011 by the Office of the National Counterintelligence Executive, a component of the Office of the Director of National Intelligence. The report, Foreign Spies Stealing US Economic Secrets in Cyberspace, examines the vulnerability of US technologies and trade secrets to cyberspace operations, the threat from specific collectors (including Russia, China, and U.S. partners), and the outlook for the future (including both “near certainties” and “possible game changers”).
Key assessments of Chinese computer network exploitation that are in the public domain have been produced either by contractors in response to tasking from the U.S.-China Economic and Security Review Commission or by private organizations. In October 2009, the review commission released Capability of the People’s Republic of China to Conduct Cyber Warfare and Computer Network Exploitation (Document 30). It examined Chinese computer network exploitation activities, strategy and operations during a military conflict, key entities in Chinese computer network operations, cyber-espionage, an operational profile of an advanced cyber intrusion and a chronology of alleged Chinese computer network exploitation activities.
A second report (Document 66), also produced for the U.S.-China review commission, and released in 2012, Occupying the High Ground, focused on Chinese capabilities for computer network exploitation. It included a look at the key entities and institutions supporting Chinese computer network operations, potential risks to the U.S. telecommunications supply chain, and the risks and reality of collaboration between U.S. and Chinese information security firms. Along with the reports for the review commission, two private organizations have produced detailed reports on PRC computer espionage activities. In 2012, a research group focused on China released a study (Document 79) based on open sources and computer-based investigations, examining the roles of several PLA organizations in cyber operations, including the Third Department of the PLA General Staff Department, its 2nd Bureau as well as its Beijing North Computer Center. Early the next year, the Mandiant computer security company released its study (Document 83) on the 2nd Bureau โ which discussed the tasking of the unit, its past espionage operations, attack lifecycle, and the unit’s infrastructure and personnel.
In contrast to the extensive public documents concerning China’s computer attack and exploitation activities, far less has appeared concerning similar Iranian activities. In 2012, Director of National Intelligence James Clapper did characterize them as “dramatically increasing in recent years in depth and complexity.” 10 A hearing in 2012 featured statements on Iranian cyber activities from two members of Congress and two non-governmental experts. (Document 71a, Document 71b, Document 71c, Document 71d).
Directives, Strategies, Policies, and Plans
While a number of presidential directives in earlier years addressed subjects such as communications security and information security, Presidential Decision Directive 63 (Document 12), Critical Infrastructure Protection, signed by President William J. Clinton on May 22, 1998, focused on protecting both “physical and cyber-based systems essential to the minimum operations of the economy and government.” Among the steps Clinton directed was the establishment of a National Infrastructure Assurance Plan, increased intelligence collection and analysis devoted to the cyber threat, and creation of a National Infrastructure Protection Center.
The George W. Bush administration produced a number of classified as well as unclassified documents concerning cyberspace. The first, National Security Presidential Directive 16 (NSPD-16) was reported to have been issued in July 2002 and provide guidelines for the conduct of offensive cyber operations. A public document, The National Strategy to Secure Cyberspace (Document 16), was released in February 2003 and was followed by the classified NSPD-38, with the same title, of July 7, 2004. A third classified directive, NSPD-54, Cyber Security and Monitoring, was issued on January 8, 2008. 11
President Obama has signed two Presidential Policy Directives concerning cybersecurity โ the still classified PPD-20 (title unknown) and PPD-21, “Critical Infrastructure Security and Resilience” (Document 86) โ the latter following the failure of two proposed pieces of cybersecurity legislation to make it through Congress. Its key components are its delineation of roles and responsibilities, of officials and agencies, its identification of three strategic imperatives, and its direction to the Secretary of Homeland Security on steps to take to implement the directive. Issued the same day was an executive order (Document 87) that focused solely on critical infrastructure cybersecurity โ including information sharing, reduction of cyber risk, and identification of critical infrastructure at greatest risk.
On May 8, 2009, the White House issued the results of its cyberspace policy review โ Cyberspace Policy Review: Assuring a Trusted and Resilient Information and Communications Infrastructure (Document 28). It produced a plan that included establishing performance metrics, preparing a cybersecurity response plan, and instituting a national public awareness and education campaign to promote cybersecurity. In May 2011 the White House released its International Strategy for Cyberspace: Prosperity, Security, and Openness in a Networked World (Document 46), which discussed the building of U.S. cyberspace policy, the future of cyberspace, as well as U.S. policy priorities and concludes with the a discussion of the implementation of U.S. strategy. Then, in early 2013, along with PPD-21 and the related executive order, the administration released Administration Strategy on Mitigating the Theft of U.S. Trade Secrets (Document 82). Part of the strategy concerns mitigating cyber theft and describes four action items – diplomatic efforts, voluntary practices by industry, enhancing domestic law enforcement operations, improving domestic legislation, and promoting public awareness.
Numerous departments also have produced cyber strategy documents at various levels of classification. In 2006, the Chairman of the Joint Chiefs of Staff produced the National Military Strategy for Cyberspace Operations (Document 23), which was classified Secret. Its introduction described it as the “comprehensive strategy of the U.S. Armed Forces to ensure U.S. military superiority in cyberspace.” Since released under the Freedom of Information Act, the document identified four strategic priorities in implementing the strategy – including gaining and maintaining the initiative to operate within adversary decision cycles and integrating cyber capabilities across the full range of military operations using cyberspace. In July 2011, that strategy was replaced by the unclassified Department of Defense Strategy for Operating in Cyberspace (Document 50) โ which noted five strategic initiatives with regard to DoD operations in cyberspace. Those initiatives include treating cyberspace as an operational domain with regard to organization, training, and equipment as well as employing new concepts to protect DoD networks and systems.
The individual military services and their components have also produced their own policy and planning documents concerning cyberspace activities. In February 2010, the Army’s Training and Doctrine Command published an unclassified pamphlet (Document 33) on how cyber operations would be integrated into the full spectrum of Army operations. The next year, the Air Force produced Air Force Doctrine Document 3-12, Cyberspace Operations (Document 60), which included a discussion of the design, planning, execution, and assessment of cyberspace operations.
Civilian departments have also produced their own strategy documents โ such as the Department of Homeland Security’s November 2011 Blueprint for a Secure Cyber Future (Document 58), which listed four cybersecurity goals (including reducing exposure to cyber risk and increasing resilience) and nine means for achieving those goals.
In addition to presidential directives, departmental directives also serve to state policies as well as assign responsibilities. Thus, the 2006 DoD Directive 3600.01 (Document 22), “Information Operations,” assigned the Assistant Secretary of Defense for Networks and Information Integration responsibilities with regard to computer network defense โ a responsibility since assumed by the department’s Chief Information Officer.. A January 2010 directive (Document 31) focuses on protection of unclassified Defense Department information that passes through or resides on Defense Industrial Base information systems and networks.
The Department of Energy has also issued its own directives concerning cybersecurity โ including a September 2010 directive (Document 36) on the department’s cybersecurity management policy, including a statement of objectives, principles, responsibilities, and implementation, as well as a May 2011 directive (Document 48) which stipulates that the department’s cybersecurity policy be based on a risk management approach.
Organizations
U.S. government organizations involved in cyberspace activities (excluding those involved in evaluating programs) can be found in the Intelligence Community, Department of Defense, and several civilian departments or agencies – including the Federal Bureau of Investigation and the Department of Homeland Security.
The most senior U.S. official concerned with the analysis of intelligence concerning foreign cyber capabilities and activities is a member of the DNI’s National Intelligence Council โ the National Intelligence Officer for Cyber Issues โ a position first established in May 2011. Sometime in the late 1990s, an Information Operations Center was established within the CIA’s Directorate of Operations (now the National Clandestine Service). It absorbed some of the functions of the Directorate of Science and Technology’s Clandestine Information Technology Office. The office was officially described as being responsible for addressing “collection capabilities within emerging information technologies.” The Center’s Analysis Group is located in the Directorate of Intelligence and evaluates foreign threats to U.S. computer systems, particularly those that support critical infrastructure. 1 2
The National Security Agency’s involvement in cyber security is a consequence of its long-time role in insuring first communications and then information security for various components of the government and private sector as well as its need to insure the security of the computers it has relied on heavily for decades (e.g. Document 2, Document 3, Document 4). Its role in computer network exploitation – of gathering electronic “data at rest” is a natural extension of its signals intelligence role of gathering “data in motion.” In March 1997, according to an article (Document 11) by a former deputy director, it was also assigned the mission of computer network attack.
A major step in the organization of U.S. cyberspace activities, indicative of an upgrade in attention, occurred in late June 2009, when Secretary of Defense Robert Gates ordered (Document 29) the establishment of a unified U.S. Cyber Command subordinate to the U.S. Strategic Command. In his memo Gates noted that he would recommend to the president that he appoint the director of the National Security Agency as commander of the Cyber Command, that the command would reach initial operating capability by October 2009 and full operating capability by October 2010. He also directed disestablishment of STRATCOM’s Joint Task Force โ Global Network Operations (JTF-GNO) and Joint Functional Component Command โ Network Warfare (JFCC-NW) prior to the new command reaching full capability. In addition, Gates wrote that his memorandum “reinforces, but does not expand, USSTRATCOM authorities and responsibilities for military cyberspace operations.”
According to a brief fact sheet (Document 38), the Cyber Command is responsible for planning, coordinating, and conducting the operations and defense of specified Department of Defense information networks.” It also, when directed, conducts “full-spectrum military cyberspace operations.” Its current headquarters organization, as depicted in an organization chart (Document 92), was released in April 2013.
Subordinate to the Cyber Command are its component commands โ Army Forces Cyber Command; the 24th Air Force (a component of the Air Force Space Command); the U.S. Fleet Cyber Command (Document 69), which oversees the Navy Information Operations Command; the Navy Cyber Warfare Development Group; the Navy Cyber Defense Operations Command; and the Marine Forces Cyber Command.
In June 2002, the Director of the FBI established a Cyber Division. The division is responsible for coordinating and supervising the FBI’s investigation of federal violations “in which the Internet, computer systems, or networks are exploited as the principal instruments or targets of terrorist organizations, foreign government-sponsored intelligence operations, or criminal activity, and for which the use of such systems is essential to that activity.” 13
The Department of Homeland Security established the National Cyber Security Division (NCSD) in June 2003 “to serve as the national focal point for cybersecurity and to coordinate implementation of the February 2003 national cyberspace strategy (Document 16). Its mission (Document 52) is to “serve as the Federal Government’s lead in assessing, mitigating and responding to cyber risks in collaboration with Federal, State and local governments, the private sector, academia, and international partners.”
Cybersecurity White Papers
The most public aspect of U.S. activities in cyberspace centers around standard cybersecurity operations. In addition to documents such as presidential and departmental directives or strategy documents that stipulate cybersecurity goals, objectives or specific activities, there are a variety of other relevant documents.
Included are a number of “white papers” which described cybersecurity efforts. In March 2010, the White House released The Comprehensive National Cybersecurity Initiative (Document 34), which described details of the initiative launched in the previous administration and provided details of a dozen different components of the effort. In February 2010, the Department of Homeland Security released a paper (Document 32) describing various cybersecurity activities โ such as the operation of the EINSTEIN intrusion detection system. In July 2011 a DHS official briefed his audience (Document 52) on a variety of topics โ including the department’s National Cyber Security Division, hacking activities directed at both government and private organizations, the Stuxnet worm, and the NIGHT DRAGON exploitation effort, and cybersecurity advisory activities.
Computer Network Exploitation
Computer network exploitation (CNE) has been defined (Document 22) as “enabling operations and intelligence collection to gather data from target or adversary automated information systems or networks.” Such exploitation operations can be intended to produce information about the computer systems and networks as a prelude to a network attack or as another method of gathering economic or military intelligence. 14
CNE operations are examined in a number of intelligence threat assessments, including the Defense Security Service (Document 26, Document 43, Document 63) assessments, as well as the report by the Office of the National Counterintelligence Executive. (Document 55). As noted above, Chinese CNE operations are discussed in two reports (Document 30, Document 66) for the U.S-China review commission as well as the reports by Project 2049 (Document 79) and the Mandiant Corporation (Document 83). In addition, an Army War College paper (Document 72) also examines Chinese cyber, including CNE, capabilities.
Computer Network Attack
Computer Network Attack (CNA) has been defined (Document 22) as “operations to disrupt, deny, degrade or destroy information resident in computers and computer networks, or the computers and networks themselves. According to former NSA official William B Black Jr. (Document 11), on March 3, 1997, the Secretary of Defense officially delegated to the National Security Agency the authority to develop CNA techniques. Prior to U.S.-led airstrikes against the Qaddafi government in March 2011, the U.S. reportedly considered a cyber offensive designed to disrupt and even disable the Libyan government’s air-defense system.15
What is widely believed to be the product of a joint U.S-Israeli CNA operation was the worm Stuxnet โ part of a U.S. CNA effort designated OLYMPIC GAMES.16 The worm was reported to have infected Iranian industrial control systems at the Natanz nuclear facility and damaged Iranian centrifuges. While there has been no official U.S. or Israeli confirmation of their involvement in the operation, it has been the subject of reports by the RAND Corporation (Document 42) and Congressional Research Service (Document 40) as well as the Symantec computer security corporation.
The CRS paper (Document 40), The Stuxnet Computer Worm: Harbinger of an Emerging Warfare Capability, provides an overview of the worm, an exploration of possible developers and future users, a discussion of whether Iran was the intended target, as well as coverage of industrial control systems vulnerabilities and critical infrastructure, national security implications, and issues for Congress. RAND’s study, A Cyberworm that Knows No Boundaries (Document 42), explores the issues raised by the Stuxnet case, the vulnerabilities exploited, the difficulties in defending against such malware, and the problems posed by organizational and legal restrictions. It also provides a short assessment of the status of U.S. defensive capabilities and efforts required to improve those capabilities.
Symantec’s initial analysis (Document 44) provided a technical analysis of the worm, exploring the attack scenario, timeline, Stuxnet architecture, installation, load point, command and control, propagation methods, payload exports, payload resources, and other topics. A subsequent Symantec report (Document 88) stated that the company had “discovered an older version of Stuxnet that can answer questions about its evolution.”
Computer Network Defense
See Document 23.
Computer network defense is defined in the DoD Information Operations directive (Document 22) as “actions taken to protect, monitor, analyze, detect, and respond to unauthorized activity within DoD information systems and computer networks.” Those actions can include counterintelligence, law enforcement, and other military capabilities. The first of these is the subject of one classified DoD directive (Document 41) โ “Counterintelligence (CI) Activities in Cyberspace.” That directive makes clear that those activities include not only counterintelligence collection and support but offensive counterintelligence operations.
Techniques for computer network defense are also the subject of two Naval Postgraduate School theses. A 2003 thesis (Document 17) explores the feasibility of employing deception against cyberterrorists, where cyberterrorists are defined by two criteria – that the aim of launching unlawful attacks or threatening such attacks on computers, networks, and the information stored in them is to intimidate or coerce a government or its people in pursuit of political or social objectives, and that the activities result either in violence against persons or property or cause enough harm to generate fear.
A 2008 thesis (Document 25) examines what the author believes to be the key elements of deterrence in cyberspace – including denial, the development and demonstration of overt punishment techniques, the establishment of thresholds, and the development and articulation of national policy – and the prospects for cyber deterrence.
Audits and Evaluations
Audits and evaluations of cybersecurity and other cyberspace operations have been conducted by the GAO and the inspectors general of the Defense, Energy, Homeland Security, and Justice departments.
The inspector general of the Department of Homeland Security produced a classified report, released with redactions (Document 54), which examined the department’s capability to share cyber threat information with other federal agencies and the private sector. A subsequent classified report, also released with redactions in August 2012 (Document 75), addressed the department’s international cybersecurity program and noted areas that could be targeted for improvement โ including developing a strategic implementation plan for foreign engagement and improving communications between the U.S. Computer Emergency Readiness Team and foreign entities.
The Department of Energy’s inspector general issued a report (Document 56) in October 2011 on the department’s unclassified cybersecurity program, which examined whether that program provided sufficient protection of its data and information systems. According to the report, corrective actions for only 11 of 35 cyber security weaknesses identified in the inspector general’s 2010 report had been completed. It also reported that there was a 60 percent growth in identified weaknesses over the 2010 report. In early 2013, the department’s inspector general issued a report (Document 84) on the cybersecurity program at the Los Alamos National Laboratory.
The Justice Department’s inspector general produced a 2011 audit report (Document 45) on the FBI’s ability to address the national security cyber intrusion threat. It reported on the FBI’s efforts in developing and operating the National Cyber Investigative Joint Task Force, and the ability of the FBI field offices to investigate national security cyber cases.
The GAO also produced a report (Document 47), released in May 2011, that evaluated the extent to which the Department of Defense and the U.S. Cyber Command had provided the military services with adequate guidance with respect to roles and responsibilities, command and control relationships, and mission requirements and capabilities with regard to cyberspace operations. Other GAO reports have examined continued challenges facing DoD (Document 49) and protection of critical infrastructure (Document 51, Document 62). A 2012 GAO report (Document 70) assessed the cyber threats to federal and other computer systems and vulnerabilities present in federal information systems and supporting critical infrastructure. A February 2013 report (Document 85) focused on the challenges facing the federal government in producing a strategic approach to cybersecurity.
Some GAO evaluations have focused on cybersecurity issues with respect to single components of critical U.S. infrastructure – including the electricity grid (Document 74), and pipelines (Document 76). The GAO’s report on securing the electricity grid examines cyber threats to the grid, actions taken to prevent attacks, and remaining challenges. The office’s pipeline study cybersecurity risks, U.S. pipeline security initiatives, and the adequacy of voluntary pipeline cybersecurity.
Legal Issues
The increasing attention to cyberspace issues has also been reflected in the examination of associated legal issues โ both in law journals and government documents.17
In November 1999, the Office of the General Counsel of the Department of Defense issued a second edition of An Assessment of International Legal Issues in Information Operations (Document 13). The section “Application to Computer Network Attacks” (pp.16-23) concludes with a one-paragraph assessment which begins, “It is far from clear the extent to which the world community will regard computer network attacks as ‘armed attacks’ or ‘uses of force,’ and how the doctrines of self-defense and countermeasures will be applied to computer network attacks.” More recently, an Air Force instruction (Document 53) specifies the responsibilities of different Air Force components for legal reviews of weapons and cyber capabilities as well as the content of such reviews.
Legal issues have also been examined by the Congressional Research Service. In a March 2012 paper (Document 65), CRS explored Fourth Amendment, civil liberties, and privacy issues related to the protection of critical infrastructure and the sharing of cybersecurity information โ as well as the possibility of conflicts between state and federal cybersecurity law. Another CRS study (Document 73) examines possible cyber-related changes to 28 different statutes.
The question of whether the U.S. Cyber Command had sufficient legal authority to carry out its mission was the catalyst for an exchange of letters (Document 68a, Document 68b, Document 68c), beginning in March 2012, between Senator John McCain (R-AZ) and General Keith B. Alexander, Director of the National Security Agency and the commander of the U.S. Cyber Command.
