1. Physical Access Controls
Physical access controls aim to prevent unauthorized physical access to buildings, equipment, or areas containing sensitive assets. They form the first line of defense in a layered security model and are crucial in deterring, detecting, delaying, and responding to intrusions. These controls are often integrated with electronic systems, environmental controls, and human security protocols.
a. Bollards
Purpose: Prevent vehicle-based attacks (e.g., ram-raiding), unauthorized parking, or accidental collisions near sensitive areas.
Types:
- Fixed bollards: Permanently installed, often concrete or steel-filled, providing constant protection.
- Retractable/hydraulic bollards: Automatically lower for authorized vehicles via keycard, remote, or plate recognition.
- Removable bollards: Manually lifted/removed for temporary access control.
Use Case:
- Installed outside the perimeter of:
Financial institutions
Embassies
Critical infrastructure
- Financial institutions
- Embassies
- Critical infrastructure
- Real-Life Example: A Tier 3 data center uses retractable hydraulic bollards at its vehicle checkpoint. Only authenticated personnel vehicles are allowed beyond this point, preventing vehicle-borne IED threats or ramming attacks.
