Government cybersecurity requirements, including the Cybersecurity Maturity Model Certification (CMMC), DFARS 252.204-7012, FedRAMP, controlled unclassified information (CUI), and NIST SP 800-171 requirements;
Evolving sourcing issues such as Section 889, counterfeit part requirements, Section 5949 semiconductor product and service restrictions, and limitations on sourcing a variety of products from China; and

On December 23, 2022, President Biden signed the James M. Inhofe National Defense Authorization Act for Fiscal Year 2023 (the “FY2023 NDAA”) into law.  As described in Covington’s Client Alert, FY23 NDAA: Provisions of Interest for Almost All Government Contractors, the FY23 NDAA contains provisions of interest for almost all U.S. Government contractors.  One provision likely to be of particular interest to U.S. contractors who provide or plan to provide cloud computing services to the U.S. Government is the FedRAMP Authorization Act (the “Act”), which codifies the Federal Risk and Authorization Management Program (“FedRAMP”).

Of note, the Act creates a “presumption of adequacy” that cloud providers with authorization from one agency can use that authorization with other agencies. This is an expansion compared to the current process which allows authorizations by the FedRAMP Joint Authorization Board, but not authorizations from individual agencies, to serve as the basis for an agency’s own authorization process.  It also creates the Federal Secure Cloud Advisory Committee, comprised of 15 members of the public and private sector, to provide recommendations regarding FedRAMP and the acquisition of cloud services more generally.
