Physical Security

Physical security describes security measures that are designed to deny unauthorized access to facilities,equipment and resources, and to protect personnel and property from damage or harm (such as espionagetheft, or terroristattacks). 

Physical security involves the use of multiple layers of interdependent systems which include CCTVsurveillance, security guardsprotective barrierslocksaccess control protocols, and many other techniques.

Some external and internal threats to organisations and their staff will constantly evolve and so all procedures and technology should be kept under constant review.

 Physical security systems for protected facilities are generally intended to:

  • deter potential intruders (e.g. warning signs and perimeter markings)
  • distinguish authorized from unauthorized people (e.g. using keycards/access badges)
  • delay, frustrate and ideally prevent intrusion attempts (e.g. strong walls, door locks and safes)
  • detect intrusions and monitor/record intruders (e.g. intruder alarms and CCTV systems);
  • trigger appropriate incident responses (e.g. by security guards and police).
