U.S. lawmakers and agencies are advancing multiple efforts to sustain and strengthen cybersecurity capabilities, with some federal authorities at risk of lapsing if Congress fails to avert a government shutdown. Nextgov/FCW reported that the Cybersecurity Information Sharing Act of 2015—which provides liability protections to enable private-sector sharing of threat intelligence with the government—and the National Cybersecurity Protection System (a federal civilian network intrusion-detection and prevention capability) were both tied to Department of Homeland Security funding legislation and faced imminent expiration absent reauthorization. The same DHS legislative vehicle was also described as key to reauthorizing the State and Local Cybersecurity Grant Program, which has provided $1B to improve cybersecurity at state and local entities.
In parallel, Congress is considering sector-specific measures to improve resilience in energy and utility environments, while the Department of Energy continues operational readiness exercises. Nextgov/FCW highlighted proposed legislation including the Pipeline Cybersecurity Preparedness Act (DOE-led programs to improve pipeline/LNG cybersecurity, information sharing, and incident response coordination) and the Rural and Municipal Utility Cybersecurity Act (expanding grant and technical assistance for smaller utilities, with $250M proposed for FY2026–2030 and protections for sensitive shared cyber information). Separately, Industrial Cyber reported on DOE’s annual Liberty Eclipse exercise on Plum Island, which uses an isolated grid environment to train utilities and partners to detect, respond to, and recover from simulated attacks including ransomware and stealthy compromise scenarios spanning IT/OT and real-time operations teams.

7 events from the most recent confirmed update back to the earliest known activity.
As Congress worked to avert a shutdown, officials warned that major cybersecurity authorities, including the Cybersecurity Information-Sharing Act and the National Cybersecurity Protection System, could lapse again on Jan. 30 if not reauthorized.
DOE CESER hosted the annual Liberty Eclipse exercise on Plum Island, bringing together utilities, national laboratories, and government defenders for live-fire simulations of ransomware, stealth intrusions, data theft, and disruption in an isolated grid environment.
Three U.S. House measures—the Pipeline Cybersecurity Preparedness Act, the Rural and Municipal Utility Cybersecurity Act, and the SECURE Grid Act—were put forward to improve cybersecurity, resilience, information sharing, and planning across energy and pipeline sectors.
After the prior lapse, lawmakers temporarily extended key cybersecurity authorities, including the Cybersecurity Information-Sharing Act, through Jan. 30, 2026.
The Cybersecurity Information-Sharing Act of 2015 expired during a 43-day government shutdown late in the prior year, interrupting legal protections for companies that share cyber threat intelligence with the government.
The Department of Energy expanded the earlier effort to include power utilities and conducted the first full-scale Liberty Eclipse exercise, using realistic grid cyberattack simulations to train defenders.
A DARPA effort began focusing on the military’s reliance on the commercial power grid, laying the foundation for what later became the Liberty Eclipse exercise program.
