[CISSP] Domain Physical Security

Domain Physical Security

Primary goals of physical security

• Deter
• Delay
• Detect
• Assess
• Respond

Elctrical Power Issues

• Spike Mometary high voltage
• Surge Prolonged high voltage
• Fault Momentary power out
• Blackout Prolonged loss of power
• Sag/Dip Momentary low voltage
• Brownout Prolonged power supply this is below normal voltage

Fire type

• A common combustible
• B Liquid fire
• C Electrical Fire
• D Metals such as Magnesium

Portable extinguishers should be placed within 50 feet of electrical equipment and be inspected quarterly.

Perimeter intrusion and detection assessment sytems(PIDAS) consist of boundary fencing with motion detectors.

Seismic system is sensitive to sounds and vibrations and detects the changes in the noise level of an area it is placed within.

Somke-activated detectors use photoelectric optical detectors to detect changes in light intensity.

A passive infrared system measures any changes in heat waves for a specified area.

Lighting is an important part of physical security.
