Why are redundant systems important in security design?

Explanation:
Redundant systems are built to keep security operations running even when something fails. In security design, continuous monitoring, access control, and alarms must stay active, so if a sensor, server, or link stops working, a backup component can take over immediately. This failover minimizes gaps that an attacker could exploit and maintains enforcement of security measures without noticeable interruption. While redundancy can add some maintenance needs and does not aim to slow down maintenance or reduce resilience, its primary value is preserving operations during component failures.
