The Department of Defense (DoD) finalized revisions to the eligibility criteria for the voluntary Defense Industrial Base (DIB) Cybersecurity (CS) Program. These revisions allow all defense contractors who own or operate an unclassified information system that processes, stores, or transmits covered defense information to benefit from bilateral information sharing. DoD also finalized changes to definitions and some technical corrections for readability. The DIB CS Program currently provides cyber threat information to cleared defense contractors. Expanding participation allows a broader community of defense contractors to participate in the DIB CS Program and is in alignment with the National Defense Strategy.
