Background

Since the early 1990s, the explosion in computer interconnectivity, most notably growth in the use of the Internet, has revolutionized the way organizations conduct business, making communications faster and access to data easier. However, this widespread interconnectivity has increased the risks to computer systems and, more importantly, to the critical operations and infrastructures that these systems support, such as telecommunications, power distribution, national defense, and essential government services.

Malicious attacks, in particular, are a growing concern. The National Security Agency has determined that foreign governments already have or are developing computer attack capabilities, and that potential adversaries are developing a body of knowledge about U.S. systems and methods to attack them. In addition, reported incidents have increased dramatically in recent years. Accordingly, there is a growing risk that terrorists or hostile foreign states could severely damage or disrupt national defense or vital public operations through computer-based attacks on the nation’s critical infrastructures. Since 1997, in reports to the Congress, we have designated information security a governmentwide high-risk area. Our most recent report in this regard, issued in January, noted that, while efforts to address the problem have gained momentum, federal assets and operations continue to be highly vulnerable to computer-based attacks.

To develop a strategy to reduce such risks, in 1996, the President established a Commission on Critical Infrastructure Protection. In October 1997, the commission issued its report, stating that a comprehensive effort was needed, including “a system of surveillance, assessment, early warning, and response mechanisms to mitigate the potential for cyber threats.” The report said that the Federal Bureau of Investigation (FBI) had already begun to develop warning and threat analysis capabilities and urged it to continue in these efforts. In addition, the report noted that the FBI could serve as the preliminary national warning center for infrastructure attacks and provide law enforcement, intelligence, and other information needed to ensure the highest quality analysis possible.

In May 1998, PDD 63 was issued in response to the commission’s report. The directive called for a range of actions intended to improve federal agency security programs, establish a partnership between the government and the private sector, and improve the nation’s ability to detect and respond to serious computer-based attacks. The directive established a National Coordinator for Security, Infrastructure Protection, and Counter-Terrorism under the Assistant to the President for National Security Affairs. Further, the directive designated lead agencies to work with private-sector entities in each of eight industry sectors and five special functions. For example, the Department of the Treasury is responsible for working with the banking and finance sector, and the Department of Energy is responsible for working with the electric power industry.

PDD 63 also authorized the FBI to expand its NIPC, which had been originally established in February 1998. The directive specifically assigned the NIPC, within the FBI, responsibility for providing comprehensive analyses on threats, vulnerabilities, and attacks; issuing timely warnings on threats and attacks; facilitating and coordinating the government’s response to cyber incidents; providing law enforcement investigation and response; monitoring reconstitution of minimum required capabilities after an infrastructure attack; and promoting outreach and information sharing.

Multiple Factors Have Limited Development of Analysis and Warning Capabilities

PDD 63 assigns the NIPC responsibility for developing analytical capabilities to provide comprehensive information on changes in threat conditions and newly identified system vulnerabilities as well as timely warnings of potential and actual attacks. This responsibility requires obtaining and analyzing intelligence, law enforcement, and other information to identify patterns that may signal that an attack is underway or imminent.

Since its establishment in 1998, the NIPC has issued a variety of analytical products, most of which have been tactical analyses pertaining to individual incidents. These analyses have included (1) situation reports related to law enforcement investigations, including denial-of-service attacks that affected numerous Internet-based entities, such as eBay and Yahoo and (2) analytical support of a counterintelligence investigation. In addition, the NIPC has issued a variety of publications, most of which were compilations of information previously reported by others with some NIPC analysis.

Strategic analysis to determine the potential broader implications of individual incidents has been limited. Such analysis looks beyond one specific incident to consider a broader set of incidents or implications that may indicate a potential threat of national importance. Identifying such threats assists in proactively managing risk, including evaluating the risks associated with possible future incidents and effectively mitigating the impact of such incidents.

Three factors have hindered the NIPC’s ability to develop strategic analytical capabilities.

First, there is no generally accepted methodology for analyzing strategic cyber-based threats. For example, there is no standard terminology, no standard set of factors to consider, and no established thresholds for determining the sophistication of attack techniques. According to officials in the intelligence and national security community, developing such a methodology would require an intense interagency effort and dedication of resources.

Second, the NIPC has sustained prolonged leadership vacancies and does not have adequate staff expertise, in part because other federal agencies have not provided the originally anticipated number of detailees. For example, as of the close of our review in February, the position of Chief of the Analysis and Warning Section, which was to be filled by the Central Intelligence Agency, had been vacant for about half of the NIPC’s 3-year existence. In addition, the NIPC had been operating with only 13 of the 24 analysts that NIPC officials estimate are needed to develop analytical capabilities.

Third, the NIPC did not have industry-specific data on factors such as critical system components, known vulnerabilities, and interdependencies. Under PDD 63, such information is to be developed for each of eight industry segments by industry representatives and the designated federal lead agencies. However, at the close of our work in February, only three industry assessments had been partially completed, and none had been provided to the NIPC.

To provide a warning capability, the NIPC established a Watch and Warning Unit that monitors the Internet and other media 24 hours a day to identify reports of computer-based attacks. As of February, the unit had issued 81 warnings and related products since 1998, many of which were posted on the NIPC’s Internet web site. While some warnings were issued in time to avert damage, most of the warnings, especially those related to viruses, pertained to attacks underway. The NIPC’s ability to issue warnings promptly is impeded because of (1) a lack of a comprehensive governmentwide or nationwide framework for promptly obtaining and analyzing information on imminent attacks, (2) a shortage of skilled staff, (3) the need to ensure that the NIPC does not raise undue alarm for insignificant incidents, and (4) the need to ensure that sensitive information is protected, especially when such information pertains to law enforcement investigations underway.

However, I want to emphasize a more fundamental impediment. Specifically, evaluating the NIPC’s progress in developing analysis and warning capabilities is difficult because the federal government’s strategy and related plans for protecting the nation’s critical infrastructures from computer-based attacks, including the NIPC’s role, are still evolving. The entities involved in the government’s critical infrastructure protection efforts have not shared a common interpretation of the NIPC’s roles and responsibilities. Further, the relationships between the NIPC, the FBI, and the National Coordinator for Security, Infrastructure Protection, and Counter-Terrorism at the National Security Council have been unclear regarding who has direct authority for setting NIPC priorities and procedures and providing NIPC oversight. In addition, the NIPC’s own plans for further developing its analytical and warning capabilities were fragmented and incomplete. As a result, there were no specific priorities, milestones, or program performance measures to guide NIPC actions or provide a basis for evaluating its progress.

The administration is currently reviewing the federal strategy for critical infrastructure protection that was originally outlined in PDD 63, including provisions related to developing analytical and warning capabilities that are currently assigned to the NIPC. On May 9, the White House issued a statement saying that it was working with federal agencies and private industry to prepare a new version of a “national plan for cyberspace security and critical infrastructure protection” and reviewing how the government is organized to deal with information security issues.

In our report, we recommend that, as the administration proceeds, the Assistant to the President for National Security Affairs, in coordination with pertinent executive agencies, establish a capability for strategic analysis of computer-based threats, including developing related methodology, acquiring staff expertise, and obtaining infrastructure data; require development of a comprehensive data collection and analysis framework and ensure that national watch and warning operations for computer-based attacks are supported by sufficient staff and resources; and clearly define the role of the NIPC in relation to other government and private-sector entities.

NIPC Coordination and Technical Support Have Benefited Investigative and Response Capabilities

PDD 63 directed the NIPC to provide the principal means of facilitating and coordinating the federal government’s response to computer-based incidents. In response the NIPC undertook efforts in two major areas: providing coordination and technical support to FBI investigations and establishing crisis management capabilities.

First, the NIPC provided valuable coordination and technical support to FBI field offices, which established special squads and teams and one regional task force in its field offices to address the growing number of computer crime cases. The NIPC supported these investigative efforts by (1) coordinating investigations among FBI field offices, thereby bringing a national perspective to individual cases, (2) providing technical support in the form of analyses, expert assistance for interviews, and tools for analyzing and mitigating computer-based attacks, and (3) providing administrative support to NIPC field agents. For example, the NIPC produced over 250 written technical reports during 1999 and 2000, developed analytical tools to assist in investigating and mitigating computer-based attacks, and managed the procurement and installation of hardware and software tools for the NIPC field squads and teams.

While these efforts benefited investigative efforts, FBI and NIPC officials told us that increased computer capacity and data transmission capabilities would improve their ability to promptly analyze the extremely large amounts of data that are associated with some cases. In addition, FBI field offices were not yet providing the NIPC with the comprehensive information that NIPC officials say is needed to facilitate prompt identification and response to cyber incidents. According to field office officials, some information on unusual or suspicious computer-based activity had not been reported because it did not merit opening a case and was deemed to be insignificant. To address this problem, the NIPC established new performance measures related to reporting.

Second, the NIPC developed crisis management capabilities to support a multiagency response to the most serious incidents from the FBI’s Washington, D.C., Strategic Information Operations Center. From 1998 through early 2001, seven crisis action teams had been activated to address potentially serious incidents and events, such as the Melissa virus in 1999 and the days surrounding the transition to the year 2000, and related procedures have been formalized. In addition, the NIPC coordinated development of an emergency law enforcement plan to guide the response of federal, state, and local entities.

To help ensure an adequate response to the growing number of computer crimes, we recommend in our report that the Attorney General, the FBI Director, and the NIPC Director take steps to (1) ensure that the NIPC has access to needed computer and communications resources and (2) monitor implementation of new performance measures to ensure that field offices fully report information on potential computer crimes to the NIPC.

Progress in Establishing Information-Sharing Relationships Has Been Mixed

Information sharing and coordination among private-sector and government organizations are essential for thoroughly understanding cyber threats and quickly identifying and mitigating attacks. However, as we testified in July 2000,establishing the trusted relationships and information-sharing protocols necessary to support such coordination can be difficult.

NIPC success in this area has been mixed. For example, the InfraGard Program, which provides the FBI and the NIPC with a means of securely sharing information with individual companies, had grown to about 500 member organizations as of January 2001 and was viewed by the NIPC as an important element in building trust relationships with the private sector. NIPC officials recently told us that InfraGard membership has continued to increase. However, of the four information sharing and analysis centers that had been established as focal points for infrastructure sectors, a two-way, information-sharing partnership with the NIPC had developed with only one—the electric power industry. The NIPC’s dealings with two of the other three centers primarily consisted of providing information to the centers without receiving any in return, and no procedures had been developed for more interactive information sharing. The NIPC’s information-sharing relationship with the fourth center was not covered by our review because the center was not established until mid-January 2001, shortly before the close of our work.

Similarly, the NIPC and the FBI have made only limited progress in developing a database of the most important components of the nation’s critical infrastructures—an effort referred to as the Key Asset Initiative. While FBI field offices had identified over 5,000 key assets, at the time of our review, the entities that own or control the assets generally had not been involved in identifying them. As a result, the key assets recorded may not be the ones that infrastructure owners consider to be the most important. Further, the Key Asset Initiative was not being coordinated with other similar federal efforts at the Departments of Defense and Commerce.

In addition, the NIPC and other government entities had not developed fully productive information-sharing and cooperative relationships. For example, federal agencies have not routinely reported incident information to the NIPC, at least in part because guidance provided by the federal Chief Information Officers Council, which is chaired by the Office of Management and Budget, directs agencies to report such information to the General Services Administration’s Federal Computer Incident Response Capability. Further, NIPC and Defense officials agreed that their information-sharing procedures needed improvement, noting that protocols for reciprocal exchanges of information had not been established. In addition, the expertise of the U.S. Secret Service regarding computer crime had not been integrated into NIPC efforts.

The NIPC has been more successful in providing training on investigating computer crime to government entities, which is an effort that it considers an important component of its outreach efforts. From 1998 through 2000, the NIPC trained about 300 individuals from federal, state, local, and international entities other than the FBI. In addition, the NIPC has advised several foreign governments that are establishing centers similar to the NIPC.

To improve information sharing, we recommend in our report that the Assistant to the President for National Security Affairs direct federal agencies and encourage the private sector to better define the types of information necessary and appropriate to exchange in order to combat computer-based attacks and to develop procedures for performing such exchanges, initiate development of a strategy for identifying assets of national significance that includes coordinating efforts already underway, and resolve discrepancies in requirements regarding computer incident reporting by federal agencies.

In our report, we also recommend that the Attorney General task the FBI Director to formalize information-sharing relationships between the NIPC and other federal entities and industry sectors and ensure that the Key Asset Initiative is integrated with other similar federal activities.
