The Department of Energy’s Unclassified Cybersecurity Program – 2024

The Federal Information Security Modernization Act of 2014 requires Federal agencies to develop, implement, and manage agency-wide information security programs. Agencies are also required to provide acceptable levels of security for the information and systems that support their operations and assets.

The Federal Information Security Modernization Act of 2014 also mandates that the Office of Inspector General conduct an independent evaluation to determine whether the Department of Energy’s unclassified cybersecurity program adequately protected its data and information systems in accordance with Federal and Department requirements.

Our fiscal year 2024 Federal Information Security Modernization Act of 2014 evaluation determined that the Department, including the National Nuclear Security Administration, had taken actions to address some of the previously identified weaknesses related to its unclassified cybersecurity program. While actions were taken to close 19 of 63 (30 percent) recommendations from our prior year audits and evaluations, 44 prior year recommendations remained open. We also issued 79 new recommendations throughout the fiscal year related to various areas of cybersecurity programs.

The weaknesses identified occurred for a variety of reasons. For instance, findings at some Department sites had occurred due to vulnerability management processes that were not fully effective in identifying, addressing, and/or remediating vulnerabilities. We also found that several sites had not fully developed and/or maintained policies and procedures to help facilitate the design and implementation of security controls.

Without improvements to address the weaknesses identified in our report, the Department may be unable to adequately protect its information systems and data from compromise, loss, or modification.

When fully implemented, the 123 recommendations made during fiscal year 2024 should help to enhance the Department’s unclassified cybersecurity program. The Department should emphasize closing findings in a timely manner, especially those findings repeated from prior years. As cybersecurity remains an ongoing challenge, it is important that the Department take action to implement the latest Federal cybersecurity requirements and enhancements to assist in ensuring adequate protection of the Department’s data and information systems at risk to emerging threats and vulnerabilities.
