As computer technology has advanced, both government and private entities have become increasingly dependent on computerized information systems to carry out operations and to process, maintain, and report essential information. Public and private organizations rely on computer systems to transmit proprietary and other sensitive information, develop and maintain intellectual capital, conduct operations, process business transactions, transfer funds, and deliver services. In addition, the Internet has grown increasingly important to American business and consumers, serving as a medium for hundreds of billions of dollars of commerce each year, and has developed into an extended information and communications infrastructure that supports vital services such as power distribution, health care, law enforcement, and national defense. Ineffective protection of these information systems and networks can result in a failure to deliver these vital services, and result in loss or theft of computer resources, assets, and funds; inappropriate access to and disclosure, modification, or destruction of sensitive information, such as national security information, PII, and proprietary business information; disruption of essential operations supporting critical infrastructure, national defense, or emergency services; undermining of agency missions due to embarrassing incidents that erode the public’s confidence in government; use of computer resources for unauthorized purposes or to launch attacks on other systems; damage to networks and equipment; and high costs for remediation. Risks to cyber-based assets can originate from unintentional or intentional threats. Unintentional threats can be caused by, among other things, natural disasters, defective computer or network equipment, and careless or poorly trained employees. Intentional threats include both targeted and untargeted attacks from a variety of sources, including criminal groups, hackers, disgruntled employees, foreign nations engaged in espionage and information warfare, and terrorists. These adversaries vary in terms of their capabilities, willingness to act, and motives, which can include seeking monetary gain or a political, economic, or military advantage. For example, adversaries possessing sophisticated levels of expertise and significant resources to pursue their objectives—sometimes referred to as “advanced persistent threats”— pose increasing risks. They make use of various techniques— or exploits—that may adversely affect federal information, computers, software, networks, and operations. Since fiscal year 2006, the number of information security incidents affecting systems supporting the federal government has steadily increased each year: rising from 5,503 in fiscal year 2006 to 67,168 in fiscal year 2014, an increase of 1,121 percent (see fig. 1). Furthermore, the number of reported security incidents involving PII at federal agencies has more than doubled in recent years—from 10,481 incidents in fiscal year 2009 to 27,624 incidents in fiscal year 2014. These incidents and others like them can adversely affect national security; damage public health and safety; and lead to inappropriate access to and disclosure, modification, or destruction of sensitive information. Recent examples highlight the impact of such incidents: In June 2015, OPM reported that an intrusion into its systems affected personnel records of about 4 million current and former federal employees. The Director of OPM also stated that a separate incident may have compromised OPM systems related to background investigations, but its scope and impact have not yet been determined. In June 2015, the Commissioner of the Internal Revenue Service (IRS) testified that unauthorized third parties had gained access to taxpayer information from its “Get Transcript” application. According to IRS, criminals used taxpayer-specific data acquired from non-IRS sources to gain unauthorized access to information on approximately 100,000 tax accounts. These data included Social Security information, dates of birth, and street addresses. In April 2015, the Department of Veterans Affairs (VA) Office of Inspector General reported that two VA contractors had improperly accessed the VA network from foreign countries using personally owned equipment. In February 2015, the Director of National Intelligence stated that unauthorized computer intrusions were detected in 2014 on OPM’s networks and those of two of its contractors. The two contractors were involved in processing sensitive PII related to national security clearances for federal employees. In September 2014, a cyber-intrusion into the United States Postal Service’s information systems may have compromised PII for more than 800,000 of its employees. Given the risks posed by cyber threats and the increasing number of incidents, it is crucial that federal agencies take appropriate steps to secure their systems and information. We and agency inspectors general have identified challenges in protecting federal information and systems, including those in the following key areas: Designing and implementing risk-based cybersecurity programs at federal agencies. Agencies continue to have shortcomings in assessing risks, developing and implementing security controls, and monitoring results. Specifically, for fiscal year 2014, 19 of the 24 federal agencies covered by the Chief Financial Officers (CFO) Actreported that information security control deficiencies were either a material weakness or a significant deficiency in internal controls over their financial reporting.agencies cited information security as a major management challenge for their agency. Moreover, inspectors general at 23 of the 24 As we testified in April 2015, for fiscal year 2014, most of the agencies had weaknesses in the five key security control categories. These control categories are (1) limiting, preventing, and detecting inappropriate access to computer resources; (2) managing the configuration of software and hardware; (3) segregating duties to ensure that a single individual does not have control over all key aspects of a computer-related operation; (4) planning for continuity of operations in the event of a disaster or disruption; and (5) implementing agency-wide security management programs that are critical to identifying control deficiencies, resolving problems, and managing risks on an ongoing basis. (See fig. 2.) Examples of these weaknesses include: (1) granting users access permissions that exceed the level required to perform their legitimate job-related functions; (2) not ensuring that only authorized users can access an agency’s systems; (3) not using encryption to protect sensitive data from being intercepted and compromised; (4) not updating software with the current versions and latest security patches to protect against known vulnerabilities; and (5) not ensuring employees were trained commensurate with their responsibilities. GAO and agency inspectors general have made hundreds of recommendations to agencies aimed at improving their implementation of these information security controls. Enhancing oversight of contractors providing IT services. In August 2014, we reported that five of six agencies we reviewed were inconsistent in overseeing assessments of contractors’ implementation of security controls. This was partly because agencies had not documented IT security procedures for effectively overseeing contractor performance. In addition, according to OMB, 16 of 24 agency inspectors general determined that their agency’s program for managing contractor systems lacked at least one required element. We recommended that OMB, in conjunction with DHS, develop and clarify guidance to agencies for annually reporting the number of contractor-operated systems and that the reviewed agencies establish and implement IT security oversight procedures for such systems. OMB did not comment on our report, but the agencies generally concurred with our recommendations. Improving security incident response activities. In April 2014, we reported that the 24 agencies did not consistently demonstrate that they had effectively responded to cyber incidents. Specifically, we estimated that agencies had not completely documented actions taken in response to detected incidents reported in fiscal year 2012 in about 65 percent of cases. In addition, the 6 agencies we reviewed had not fully developed comprehensive policies, plans, and procedures to guide their incident response activities. We recommended that OMB address agency incident response practices government-wide and that the 6 agencies improve the effectiveness of their cyber incident response programs. The agencies generally agreed with these recommendations. We also made two recommendations to DHS concerning government-wide incident response practices. DHS concurred with the recommendations and, to date, has implemented one of them. Responding to breaches of PII. In December 2013, we reported that eight federal agencies had inconsistently implemented policies and procedures for responding to data breaches involving PII. In addition, OMB requirements for reporting PII-related data breaches were not always feasible or necessary. Thus, we concluded that agencies may not be consistently taking actions to limit the risk to individuals from PII-related data breaches and may be expending resources to meet OMB reporting requirements that provide little value. We recommended that OMB revise its guidance to agencies on responding to a PII-related data breach and that the reviewed agencies take specific actions to improve their response to PII-related data breaches. OMB neither agreed nor disagreed with our recommendation; four of the reviewed agencies agreed, two partially agreed, and two neither agreed nor disagreed. Implementing security programs at small agencies. In June 2014, we reported that six small agencies (i.e., agencies with 6,000 or fewer employees) had not implemented or not fully implemented their information security programs. For example, key elements of their plans, policies, and procedures were outdated, incomplete, or did not exist, and two of the agencies had not developed an information security program with the required elements. We recommended that OMB include a list of agencies that did not report on the implementation of their information security programs in its annual report to Congress on compliance with the requirements of FISMA, and include information on small agencies’ programs. OMB generally concurred with our recommendations. We also recommended that DHS develop guidance and services targeted at small agencies. DHS has implemented this recommendation. Until federal agencies take actions to address these challenges— including implementing the hundreds of recommendations we and inspectors general have made—federal systems and information will be at an increased risk of compromise from cyber-based attacks and other threats. In addition to the efforts of individual agencies, DHS and OMB have several initiatives under way to enhance cybersecurity across the federal government. While these initiatives all have potential benefits, they also have limitations. Personal Identity Verification: In August 2004, Homeland Security Presidential Directive 12 ordered the establishment of a mandatory, government-wide standard for secure and reliable forms of identification for federal government employees and contractor personnel who access government-controlled facilities and information systems.
