(From the NSA Handbook)
All NSA personnel (employees, military assignees, and contractors) must submit for review any planned articles, books, speeches, resumes, or public statements that may contain classified, classifiable, NSA-derived, or unclassified protected information, e.g., information relating to the organization, mission, functions, or activities of NSA. Your obligation to protect this sensitive information is a lifetime one. Even when you resign, retire, or otherwise end your affiliation with NSA, you must submit this type of material for prepublication review. For additional details, contact the Information Policy Division (Q43) for an explanation of prepublication review procedures.
