LRAFB SFPC Safeguarding Classified Information in the NISP Practice Test

Two years after contract completion is the standard retention for copies of U.S. government classified information under the National Industrial Security Program. This window provides a practical period to accommodate potential security reviews, audits, or declassification actions while avoiding unnecessary long-term storage burdens. The Government Contracting Activity can override this default with explicit instructions, and those directions would apply. Shorter durations like one year wouldn’t cover typical post-contract oversight, while longer periods such as three or five years exceed the standard requirement.
