The advent of the Internet of Things (IOT) has transformed the outlook of the global physical security services market. Physical security comprises three essential elements, which include access control, surveillance, and testing. The physical sites are secured against attacks, accidents, or environmental disasters using locks, fencing, biometric access control systems, access control cards, and fire suppression systems. Physical locations are monitored by surveillance cameras and notification systems, including heat sensors, intrusion detection sensors, and smoke detectors. Disaster recovery procedures and policies require periodic scrutiny to ensure better safety and reduce the time taken for recovering from disasters. Physical security includes protection of hardware, software, data, personnel, and networks against physical events and actions, which could potentially cause damage or loss to an organization. It safeguards organizations from natural disasters, fire, theft, vandalism, and terrorism. It uses multiple layers of interdependent systems, which include security guards, CCTV surveillance, locks, protective barriers, access control protocols, and other similar techniques.
