Final answer:
Mary should review the DSS Manual 5105.21, Volume 3, the NISPOM, and additional guidance from her SAP program manager or security office.
Step-by-step explanation:
In order to review guidance directly applicable to all Department of Defense (DoD) Special Access Programs (SAPs), Mary should review the Defense Security Service (DSS) Manual 5105.21, Volume 3. This manual contains the policies and procedures for managing SAPs within the DoD. It provides guidance on the establishment, operation, and security requirements of SAPs.
Mary should also review the National Industrial Security Program Operating Manual (NISPOM), which provides the standards and procedures for safeguarding classified information within industry. This manual contains valuable information on the security requirements for SAPs as well.
Finally, Mary should review any additional guidance or directives provided by her specific SAP program manager or security office, as they may have specific policies and procedures that apply to their SAPs.
