This domain encompasses various measures, like access controls to secure facilities, closed-circuit television (CCTV) surveillance, perimeter security, alarms, and security personnel. Additionally, environmental security includes fire prevention, detection, and suppression systems, temperature and humidity controls, and power supply redundancies to ensure continued operation in the face of environmental factors. By implementing robust physical and environmental security controls, organizations can minimize the risk of unauthorized access, theft, sabotage, and natural disasters, while also maintaining the availability and integrity of their systems and information assets.
