Final answer:
The question asks which sections of the NISPOM might not apply to all facilities. The NISPOM contains different chapters and appendices that are specific to various aspects of security; therefore, not every part is relevant to all facilities, depending on their operations and industry sector.
Step-by-step explanation:
The student's question pertains to which chapters and appendices of the National Industrial Security Program Operating Manual (NISPOM) might not apply to all facilities. This document is central to the regulation of the private sector's defense services and covers a wide array of security requirements and guidelines. Not every chapter or appendix will be relevant to all facilities since some sections are specific to types of classified information, operational environments, or industry sectors.
For instance, a chapter about safeguarding classified information in the defense contracting industry may not be relevant to a facility that does not handle classified defense contracts. Similarly, an appendix focused on overseas operations might be inapplicable to a facility that operates solely within domestic borders.
