physical security definition

Dec 10, 2015

Physical security describes security measures which are created to deny unauthorized use of facilities, equipment and resources, and to protect personnel and property from damage or injury (like espionage, theft, or terrorist attacks). Physical security entails the usage of multiple layers of interdependent systems such as security guards, CCDISPLAY surveillance, protective barriers, locks, access control protocols, and a number of other techniques.

Physical security systems for facilities that were protected are generally intended to:

Discourage potential intruders (e.g. warning indications and perimeter mark);

Find intrusions and monitor/record intruders (e.g. intruder alarms and CCDISPLAY systems); and

Trip appropriate event responses (e.g. by security guards and authorities).

Physical access security measures which are suitable for a top security prison or a military website could be improper within an office, a home or a vehicle, even though the principles are similar.

Physical security is frequently overlooked (and its significance underestimated) in favor of more specialized and dramatic problems like hacking, viruses, Trojans, and spyware. Nonetheless, violations of physical security may be carried out with little if any technical knowledge on the section of an attacker. Furthermore, accidents and natural disasters really are a part of regular life, and in the long term, are inevitable.

You will find three major elements to physical security. First, barriers may be put into the way of likely future attackers and sites may be hardened against injuries and environmental disasters. Such measures may include water sprinklers, fencing, walls, fireproof safes, and multiple locks. Second, surveillance and notification systems may be set in place, like cameras, heat sensors, smoke detectors, intrusion detectors, alarms, and lighting. Third, procedures could be implemented to apprehend attackers (rather before any damage was done) and to recuperate immediately from injuries, fires, or natural disasters.
