Redundancy
Redundancy in cybersecurity and defense refers to having duplicate or alternative systems, components, or data to ensure continuous operation and availability even if one part fails. It's like having a backup plan for critical resources.
TECHNICAL DEFINITION
Redundancy, a core principle in cybersecurity and defense architecture, involves deploying multiple identical or equivalent active/passive components, systems, or data paths to ensure fault tolerance, high availability, and resilience against single points of failure, cyberattacks, or physical damage, thereby maintaining operational continuity for critical infrastructure.
BACKGROUND
Defense in depth is a concept used in information security in which multiple layers of security controls (defense) are placed throughout an information technology (IT) system. Its intent is to provide redundancy in the event a security control fails or a vulnerability is exploited.
