Selected agencies—the Federal Aviation Administration, Indian Health Services, and Small Business Administration—had generally deployed tools intended to provide cybersecurity data to support the Department of Homeland Security's (DHS) Continuous Diagnostics and Mitigation (CDM) program. As depicted in the figure, the program relies on automated tools to identify hardware and software residin

The Securities and Exchange Commission (SEC) improved its information security by addressing weaknesses previously identified by GAO, including separating the user production network from the internal management network. However, weaknesses continue to limit the effectiveness of other security controls. In particular: (1) While SEC had issued policies and implemented controls based on those polic

The Department of Homeland Security's (DHS) National Cybersecurity Protection System (NCPS) is partially, but not fully, meeting its stated system objectives: (1) <b>Intrusion detection:</b> NCPS provides DHS with a limited ability to detect potentially malicious activity entering and exiting computer networks at federal agencies. Specifically, NCPS compares network traffic to known patterns of m

Similar to other critical infrastructures, the nation's ports face an evolving array of cyber-based threats. These can come from insiders, criminals, terrorists, or other hostile sources and may employ a variety of techniques or exploits, such as denial-of-service attacks and malicious software. By exploiting vulnerabilities in information and communications technologies supporting port operation

While the Department of Veterans Affairs (VA) has taken actions to mitigate previously identified vulnerabilities, it has not fully addressed these weaknesses. For example, VA took actions to contain and eradicate a significant incident detected in 2012 involving a network intrusion, but these actions were not fully effective: (1) The department's Network and Security Operations Center (NSOC) ana

Cyber-based threats to critical infrastructure and federal systems are evolving and growing. These threats can come from a variety of sources, including criminals and foreign nations, as well as hackers and disgruntled employees. These potential attackers have a variety of techniques at their disposal that can vastly expand the reach and impact of their actions. In addition, the interconnectivity

GAO identified a range of leading security practices for deploying and monitoring secure wireless networks and technologies that can help secure these networks. The leading practices include the following: (1) comprehensive policies requiring secure encryption and establishing usage restrictions, implementation practices, and access controls; (2) a risk-based approach for wireless deployment and

There are a number of key entities and efforts with significant influence on international cyberspace security and governance. The organizations range from information-sharing forums that are nondecision-making gatherings of experts to private organizations to treaty-based, decision-making bodies founded by countries. Their efforts include those to address topics such as incident response, techni

The goals of TIC are to secure federal agencies' external network connections, including Internet connections, and improve the government's incident response capability by reducing the number of agencies' external network connections and implementing security controls over the connections that remain. In implementing TIC, agencies could either provide their own access points by becoming an access

Although NASA has made important progress in implementing security controls and aspects of its information security program, it has not always implemented appropriate controls to sufficiently protect the confidentiality, integrity, and availability of the information and systems supporting its mission directorates. Specifically, NASA did not consistently implement effective controls to prevent, l
