Physical security describes measures that prevent or deter somebody from accessing a location or valuable data. It is as straightforward as a closed door or as sophisticated as a facility.
In the security field there area unit 3 primary components to physical security; obstacles, alarms and also the security response.
Obstacles
Obstacles area unit meant to slow threats, however won't be sufficient to prevent a significant threat. they're stand alone and frequently unattended things like barred doors, razor wire barriers and splinterless windows.
Slightly additional complicated obstacles will include:
- Access cards and combination appearance on doors
- Doors that has got to be force to enter or exit a neighborhood
- Revolving doors or turnstiles which permit one person at a time to advance
- Vehicle barriers controlled by access cards
Alarms
Security alarms system are useful for alert security response groups associate degreed to unbalance an assailant. Loud alarms, strobe light lights or bright lights area unit common alarms.
- More complicated and interactive alarms include:
- television system cameras with motion detectors
- Roving security patrols
- Guard dogs
- Birds
Security response
Security response is employed to repel or catch attackers once an event has already taken place. Security response is sometimes left to the police, however armed non-public security personnel area unit used once acceptable.
If the protection response team is correctly equipped with night-sight material, flood lights is doubly effective. 1st to assist security response groups establish specifically wherever the interloper is found and so, because the team approaches the realm, all lights area unit turned off giving the interloper visual disorder.
3 part mixtures
Each of the three elements; obstacles, alarms and security response is wont to augment another part. For example:
- A fence originally designed to be associate degree obstacle will become associate degree alarm by attaching motion detectors
- Double enclosed areas with guard dogs
- inserting signs that say there's associate degree alarm makes that alarm associate degree obstacle
- A security response team that's visible on web site acts as associate degree obstacle associate degreed as an alarm
Physical security measures meant to stop or deter somebody from accessing a location or data will ne'er be 100 percent effective. A barred door can keep a standard criminal from getting into a centrally situated building in the dark, however that very same criminal can break into an isolated house. A determined terrorist can continually be able to reach some objective, as long as he's wiling to alter his target to achieve no matter is best.
