What does the acronym NISPOM stand for?

• A. National Industrial Security Operating Manual
• B. National Information Security Procedures Manual
• C. National Industry Security Policy Manual
• D. National Integrated Security Protocol Manual

Answer: (A)

Understanding NISPOM means recognizing it as the National Industrial Security Program Operating Manual, the federal document that governs how cleared contractors protect classified information in the National Industrial Security Program. This option aligns with the recognized title by including the core terms National, Industrial Security, and Operating Manual, and corresponds to the official full form, which is National Industrial Security Program Operating Manual. The other choices change key words—Information versus Industrial, Industry instead of Industrial, or replace the concept with Policy or Protocol—so they don’t reflect the established name.
