CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-284Improper Access Control4,832Alternative mechanisms sustain access control enforcement even if the primary access control implementation is unavailable or compromised.
CWE-287Improper Authentication4,730Delivers alternative authentication approaches to verify identity when the primary authentication mechanism is unavailable or compromised.
CWE-285Improper Authorization1,230Supplies backup authorization methods to block unauthorized actions when the primary authorization process is unavailable or compromised.
CWE-693Protection Mechanism Failure476Provides alternative mechanisms to maintain security functions when the primary implementation is unavailable or compromised, directly preventing protection mechanism failure.
CWE-636Not Failing Securely ('Failing Open')27Ensures security functions remain enforced via alternatives instead of defaulting to an insecure state when the primary means fails.
