Which term best describes the National Industrial Security Program Operating Manual (NISPOM)?

The National Industrial Security Program Operating Manual (NISPOM) is best described as a primary reference because it serves as the foundational document outlining the policies, principles, and procedures for the protection of classified information within the National Industrial Security Program. NISPOM provides essential guidance and is considered a critical resource for Facility Security Officers and related personnel in ensuring compliance with federal regulations concerning classified information handling.

Given its role in dictating the standards and requirements for protective measures, reporting incidents, and conducting security education and training, NISPOM is referred to as a primary reference in the context of industrial security. It is utilized as the authoritative source for interpreting security measures and implementing practices that align with government requirements. This distinguishes it from a secondary reference, which would generally provide information that is derived from primary sources rather than serving as a key directive itself.

Additionally, while NISPOM could be viewed as a government policy guide, referring to it as a primary reference underscores its critical role in establishing concrete operational procedures and requirements within the broader legislative context.
