To what scope do perimeter procedures apply?

• A. These procedures are limited to buildings or areas where classified work is being performed
• B. These procedures apply to all buildings, whether or not classified work is performed
• C. These procedures apply only to outdoor areas
• D. These procedures apply only to common areas

Answer: (A)

Perimeter procedures establish the security boundary around spaces where classified work occurs, including the controls and monitoring used to deter and detect unauthorized access. The scope is limited to buildings or areas where classified work is performed because that’s where the sensitivity and risk reside, so safeguards are focused where they matter most. Extending these procedures to every building regardless of classified work would waste resources and complicate access unnecessarily, while limiting them to outdoor areas or only common areas misses the essential boundary around the actual secured workspace that houses or supports classified activities.
