What are redundant systems in physical security?

Redundant systems in physical security refer to backup mechanisms or systems that are designed to provide additional security measures should the primary systems fail. The concept of redundancy is integral to ensuring that security remains robust even in the event of a compromise or failure of primary systems. This could include having multiple access control systems, additional surveillance cameras, or even backup power supplies.

By implementing redundancy, organizations can minimize vulnerabilities and ensure continuous protection. For example, if an electronic access control system malfunctions, a physical lock or an alternative access method can serve as a backup, maintaining security. This layered approach is critical in physical security planning, as it creates a more resilient environment against potential threats.

In contrast, systems used only during peak hours or those that are not frequently used do not inherently contribute to redundancy, as they may not serve as reliable backups. Similarly, systems designed exclusively for emergency situations may not provide ongoing protective measures in regular circumstances, which is a key characteristic of redundant systems.
