Which component is NOT typically included in a physical security strategy?

A physical security strategy is primarily focused on protecting physical assets and ensuring the safety of personnel and property through a variety of means. This encompasses measures such as control of access, deterrent methods, and physical barriers. Lock and key systems, technical surveillance countermeasures, and fencing and barriers are all crucial elements in this realm.

Lock and key systems are fundamental for controlling access to secure areas, allowing only authorized personnel to enter. Technical surveillance countermeasures enhance physical security by detecting and mitigating eavesdropping threats or unauthorized surveillance. Fencing and barriers serve as physical deterrents, preventing unauthorized entry and protecting perimeters.

On the other hand, while cybersecurity protocols are essential for protecting information systems and data, they primarily fall under the realm of cyber security rather than physical security. Cybersecurity focuses on protecting digital assets and networks from cyber threats, which do not typically involve physical security measures. Therefore, while important in its own right, cybersecurity is not a standard component of a physical security strategy, distinguishing it from the other components listed.
