DOE Implementation of Cybersecurity Information Sharing Act Evaluation
Summary
The DOE Office of Inspector General published Evaluation DOE-OIG-26-28 finding that the Department of Energy took necessary actions to implement the Cybersecurity Information Sharing Act of 2015. The evaluation, conducted as part of a joint review with the Intelligence Community IG covering seven executive agencies, confirmed DOE's policies and procedures for sharing cyber threat indicators were sufficient, including requirements for PII removal. No formal recommendations were made due to satisfactory compliance.
What changed
The DOE OIG issued Evaluation DOE-OIG-26-28 assessing the Department's implementation of the Cybersecurity Information Sharing Act of 2015 (CISA). The evaluation examined policies and procedures for cyber threat indicator sharing, information sharing mechanisms, and implementation barriers. The OIG found DOE's policies met CISA requirements, including PII removal protocols, and that officials were unaware of any CISA-related violations. Security clearances were authorized for classified cyber threat sharing with the private sector, and the Department continued using Automated Indicator Sharing capabilities. A previous barrier regarding the Intelligence Community Analysis and Signature Tool was resolved, though information-sharing fatigue from high volumes of indicators was noted as a remaining concern with no identified impact to actual sharing operations.
As a compliance evaluation with no recommendations issued, this report does not impose new requirements or deadlines on DOE or other agencies. Federal agencies subject to CISA's biennial IG reporting requirements should note that DOE demonstrated full compliance with cyber threat information sharing protocols. Entities participating in Automated Indicator Sharing or receiving classified threat indicators should continue existing procedures. The evaluation confirms no enforcement action or penalty context applies.

The Department of Energy Took Actions Necessary to Implement the Cybersecurity Information Sharing Act of 2015
The Cybersecurity Information Sharing Act of 2015 (Cybersecurity Act) requires agencies to develop processes and procedures to facilitate and promote the timely sharing of cyber threat information. It also requires the Office of Inspector General to report to Congress at least every 2 years on the sufficiency of information sharing policies, procedures, and guidelines.
We participated in a joint review led by the Office of the Inspector General of the Intelligence Community to assess efforts by seven executive agencies, including the Department of Energy, to implement Cybersecurity Act requirements related to policies and procedures, information sharing, and barriers.
Our evaluation determined that the Department had taken the actions necessary to implement the requirements of the Cybersecurity Act. Specifically, we found that policies and procedures related to the sharing of cyber threat indicators were sufficient and included requirements for the removal of personally identifiable information. Officials also indicated that they were unaware of any violations by the Department regarding the failure to remove personally identifiable information related to a cybersecurity threat. In addition, Department officials informed us that security clearances were authorized for the purpose of sharing classified cyber threat indicators and defensive measures with the private sector. The Department also continued to share and receive cyber threat indicators using Automated Indicator Sharing capabilities during the period under review.
Although the barrier related to the quality of cyber threat indicators received from the Office of the Director of National Intelligence was mitigated since our 2023 evaluation, with the discontinued active feed of the Intelligence Community Analysis and Signature Tool, Department officials noted another barrier related to the quality of cyber threat indicators shared with the Department and industry partners. Specifically, information-sharing fatigue from the large quantity of cyber threat indicators was noted as an issue. While Department officials noted this barrier, we did not identify any associated impact to the sharing of threat indicators and defensive measures from calendar year 2023 through calendar year 2024.
Due to the Department’s continued implementation of the Cybersecurity Act, we did not make formal recommendations for improvement.
