Physical Security

Physical Security refers to the protection of personnel, hardware, software, networks, and data from physical actions and events that could cause damage or loss. It involves implementing measures to mitigate physical threats to an organization's assets. Key components of Physical Security include: 1. Access Controls: These restrict entry to facilities and sensitive areas through methods like mantraps, key cards, biometric systems, and security guards. 2. Surveillance Systems: CCTV cameras, motion detectors, and alarm systems monitor facilities for unauthorized activities. 3. Environmental Controls: These protect against environmental threats including HVAC systems, fire suppression, humidity controls, and water leak detection. 4. Perimeter Security: Fences, gates, bollards, and barriers establish a physical boundary around facilities. 5. Secure Areas: Server rooms, wiring closets, and data centers require special protection with reinforced walls, specialized locks, and access logs. 6. Hardware Security: Cable locks, equipment cages, and secure mounting prevent theft of devices. 7. Technical Surveillance Countermeasures: Faraday cages and RF shielding protect against eavesdropping. 8. Lighting: Well-lit areas deter criminals and enhance surveillance effectiveness. 9. Physical Security Policies: Documentation detailing procedures for visitor management, employee access, and security incident response. Physical security is fundamental to an overall security program as even the strongest cybersecurity measures can be compromised through physical access to systems. It represents the first line of defense in a defense-in-depth strategy. When preparing for CompTIA Security+, understand how physical security integrates with technical controls to create comprehensive protection for organizational assets.
