Physical security monitoring

Access to buildings containing critical systems must be constantly monitored to detect unauthorized access or suspicious activity. The following issues should be taken into account in monitoring practices:

• touch, sound or motion detectors that trigger an intrusion alarm
• covering exterior doors and windows using sensors
• supervision of unstaffed and otherwise important (e.g. server or communication technology) premises
• regular testing of alarm systems

Information related to surveillance systems should be kept confidential, as disclosure of information can facilitate undetected breaches. The monitoring systems themselves must also be properly protected, so that the recordings or system status cannot be affected without permission.

Organisation's premises and the operating environments of the equipment are actively protected by security.

Security personnel use camera surveillance to verify unauthorized access, sabotage, or other alarms at the organization's premises.
