The SEVEN Act establishes an interagency working group to assess vulnerabilities in the Signaling System 7 telecommunications protocol and protect U.S. military and commercial telecommunications networks from security threats. The working group, led by the Commerce Department with representatives from major federal agencies including the Department of Defense, Department of Homeland Security, FBI, and the Federal Communications Commission, must produce annual reports for six years examining foreign threats to this outdated protocol, current government and private sector protections, and recommendations for improving network security. The bill affects telecommunications companies of all sizes, government agencies, and Congress, with reports to be shared among relevant congressional committees and state governors, though the detailed findings will be classified with an option for unclassified summaries. The working group must convene within 60 days of enactment and deliver its first report within one year, followed by annual assessments and congressional briefings for the next five years.
