Security Requirements for 03.10.02 Monitor Facility

Monitoring 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.

Discussion

The 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.

Examples

  1. Example 1

    You 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].

Assessment Methods

Examine
The process of reviewing, inspecting, observing, studying, or analyzing assessment objects (e.g., policies, procedures, plans, system designs, mechanisms) to facilitate understanding, achieve clarification, or obtain evidence.Example: An assessor reads the access control policy and inspects system configuration settings to confirm they match.

Not all of the evidence listed is required to meet this requirement — check the items your organization has collected.

Interview
The process of holding discussions with individuals or groups within an organization to facilitate understanding, achieve clarification, or identify the location of evidence.Example: An assessor asks a system administrator to describe how user accounts are approved, reviewed, and disabled.
  • Personnel with physical access monitoring responsibilities
  • Personnel with incident response responsibilities
  • Personnel with information security responsibilities
Test
The process of exercising assessment objects (e.g., activities, mechanisms) under specified conditions to compare actual behavior with expected behavior.Example: An assessor attempts to sign in with a disabled account to confirm that access is denied.
  • Organizational processes for monitoring physical access
  • Mechanisms supporting or implementing physical access monitoring
  • Mechanisms supporting or implementing the review of physical access logs

Potential Assessment Considerations

  • Is physical access monitored to detect and respond to physical security incidents [c, d]?
