Two areas of physical security being referenced are outside perimeter security and inside perimeter security. Outside perimeter security covers the external barriers and measures that keep threats away from the building—things like fences, gates, lighting, cameras, guards, and external surveillance that deter, detect, and delay intruders before they reach the interior. Inside perimeter security focuses on protecting what’s inside once access is gained, including controlled entry points, badge or biometric access, secure rooms, restricted zones, and continuous monitoring to prevent misuse of authorized access or theft of assets. Together, these two layers describe how physical security defends a site from the outside in.

The other options involve cyber or administrative aspects rather than physical barriers. Digital encryption and authentication protect data and identities in computer systems, not physical sites. Asset management and risk assessment are important security practices but pertain to governance and planning rather than the physical protections around a facility. Perimeter firewall and intrusion detection relate to network security, not the physical enclosure and internal access controls.
