Physical security describes measures designed to ensure the physical protection of IT assets like facilities, equipment, personnel, resources and other properties from damage and unauthorized physical access. Physical security measures are taken in order to protect these assets from physical threats including theft, vandalism, fire and natural disasters.
Physical security is often the first concern in facilities with high asset concentration, especially that used in critical systems for business processes. Physical security is especially important for IT resources, as their proper operation demands that the hardware assets and infrastructure they are running on be kept away from anything that could hinder their function. This includes tampering by unauthorized personnel and unforeseen events like accidents and natural disasters.
Access control equipment and Surveillance Cameras are the most popular used methods to reach the physical security.
