What is described by security redundancy?

Security redundancy refers to the implementation of multiple differing security controls that work together to provide comprehensive protection for the same assets. This concept enhances the overall security posture of an organization by ensuring that if one security measure fails or is bypassed, additional measures are still in place to mitigate potential risks and threats.

For instance, a company might use firewalls, intrusion detection systems, and encryption all at once to protect its sensitive data. If one control has a misconfiguration or is compromised, the other controls can still provide a layer of security, thus reducing the likelihood of a security breach. Implementing security redundancy is a best practice in managing cloud security, as it addresses different types of vulnerabilities and mitigates various forms of attacks. This approach fosters a defense-in-depth strategy, which aims to cover all possible angles of vulnerability within an organization's security framework.
