Protect and monitor the physical facility and support infrastructure for organizational systems.
DiscussionMonitoring of physical access includes publicly accessible areas within organizational facilities. This can be accomplished, for example, by the employment of guards; the use of sensor devices; or the use of video surveillance equipment such as cameras. Examples of support infrastructure include system distribution, transmission, and power lines. Security controls applied to the support infrastructure prevent accidental damage, disruption, and physical tampering. Such controls may also be necessary to prevent eavesdropping or modification of unencrypted transmissions. Physical access controls to support infrastructure include locked wiring closets; disconnected or locked spare jacks; protection of cabling by conduit or cable trays; and wiretapping sensors.
Further DiscussionThe infrastructure inside of a facility, such as power and network cables, is protected so that visitors and unauthorized employees cannot access it. The protection is also monitored by security guards, video cameras, sensors, or alarms.
ExampleYou are responsible for protecting your IT facilities. You install video cameras at each entrance and exit, connect them to a video recorder, and show the camera feeds on a display at the reception desk [c,d]. You also make sure there are secure locks on all entrances, exits, and windows to the facilities [a,b].
Potential Assessment Considerations
- Is physical access monitored to detect and respond to physical security incidents [c, d]?
