The purpose of this memorandum is to notify you that we are initiating the subject audit. We are conducting this audit as required by the Cybersecurity Information Sharing Act of 2015, 6 U.S.C. §§ 1507 et seq. (CISA). CISA requires the Inspectors General of seven Federal entities (Department of Commerce, Defense, Energy, Homeland Security, Justice, Treasury, and the Office of the Director of National Intelligence) to jointly report to Congress once every 2 years on the actions of the Executive Branch of the U.S. Government to implement CISA requirements. The Inspectors General will submit an unclassified, interagency report to Congress by December 2025.
