Which inspection pattern is suggested for perimeter controls?

• A. Inspections should occur on every person, or every other person, as appropriate
• B. Inspections should occur on no one
• C. Inspections should target only visitors
• D. Inspections should be performed only during off-hours

Answer: (A)

Perimeter controls rely on consistently screening people as they enter restricted areas to prevent unauthorized access or hidden objects from crossing the boundary. The best approach is to inspect every person entering the perimeter, and, when needed due to workload or flow, inspect every other person as appropriate. This pattern provides thorough coverage so that employees, contractors, and visitors are all checked, reducing the chance that someone with restricted access or prohibited items slips through. Inspecting no one leaves a security gap. Focusing only on visitors misses other personnel who still need access and can inadvertently bypass controls. Limiting inspections to off-hours creates a vulnerability during peak times when the perimeter is most active. By applying full or alternating inspections, the perimeter remains protected while balancing practical operations.
