Physical & environmental security
Physical and environmental security ensures that only authorized personnel can physically reach servers, networking gear, and sensitive documents. Frameworks require this because logical security controls are ineffective if an attacker has direct physical access to the hardware.
Implement it once
- Install electronic badge readers or biometric locks on all perimeter doors and data center entrances.
- Deploy CCTV cameras at all entry and exit points with a defined retention period for footage.
- Maintain a formal visitor management process requiring sign-ins and continuous escorts.
- Secure sensitive hardware in locked racks or dedicated rooms separate from general office space.
- Implement environmental protections, including fire suppression systems and climate control (HVAC) for server areas.
Evidence it produces
- Access logs showing timestamps of entry and exit for authorized personnel.
- A current list of approved individuals with physical access permissions.
- Signed visitor logs documenting the date, time, and purpose of guest visits.
- Maintenance records and test certificates for fire suppression and cooling systems.
- Documented policies defining physical security zones and access levels.
Where it counts
Most major security standards share a common goal of preventing unauthorized physical proximity to sensitive data. By establishing one rigorous set of physical controls, an organization satisfies the equivalent requirements across multiple frameworks simultaneously without duplicating effort.
