This is the Congressional Budget Office (CBO) Cost Estimate as ordered reported by the Senate Committee on Homeland Security and Governmental Affairs on November 3, 2021. From the Document: "S. 2993 would establish a cybersecurity exercise program to evaluate strategies and plans for responding to cyber incidents. The Cybersecurity and Infrastructure Security Agency currently operates the Cyber Exercise Program, which meets the requirements of the bill. Because S. 2993 would codify the agency's current practices, implementing the bill would not affect the federal budget. On May 27, 2021, CBO transmitted a cost estimate for H.R. 3223, the CISA [Cybersecurity and Infrastructure Security Agency] Cyber Exercise Act, as ordered reported by the House Committee on Oversight and Reform on May 18, 2021. The two bills are similar, and CBO's estimates of their costs are the same."
