Testing Physical Security Controls

A subject performs a limited physical action to determine whether access controls, security personnel, surveillance, visitor procedures, alarms, or other physical safeguards prevent or identify unauthorized presence.

The subject may test a restricted door, present a credential at an unauthorized area, follow another person through a controlled entrance, remain in an area after their approved access period, or enter a sensitive location without a clear operational reason. They may also observe whether security personnel challenge unfamiliar subjects or whether physical access violations generate follow-up activity.

The behavior is distinct from general physical exploration because the subject actively interacts with or crosses a security boundary to evaluate the result. The test may support later unauthorized entry, physical sabotage, theft, access to infrastructure, or facilitation of another person’s presence.
