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-287Improper Authentication5,200+Requires unique identification and authentication of services before any communications, directly mitigating improper authentication.
CWE-306Missing Authentication for Critical Function3,300+Mandates authentication prior to establishing communications with services, preventing missing authentication for this critical function.
CWE-346Origin Validation Error700+Requires unique identification of the service before communications, addressing failures to validate the origin of the interaction.
CWE-290Authentication Bypass by Spoofing700+Unique identification and authentication of services before communications makes spoofing of service identities substantially harder.
CWE-940Improper Verification of Source of a Communication Channel56Enforces verification of the source of a communication channel by requiring identification and authentication of services first.
