Notably, the final rule clarifies by CDI (covered defense information). This term is used in the DFARS (Defense Federal Acquisition Regulation Supplement). It defines CDI to include 4 categories; covered technical information (CTI); controlled unclassified information (CUI); operations security; export controlled information; and any other information identified or otherwise marked in the contract.
