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-862Missing Authorization10,200+Requires explicit authorization before any identifier can be assigned, preventing missing authorization.
CWE-284Improper Access Control6,900+Ensures identifiers are properly authorized and assigned, supporting effective access control.
CWE-287Improper Authentication5,200+Provides unique, authorized identifiers that are foundational to preventing authentication weaknesses.
CWE-863Incorrect Authorization3,900+Enforces correct authorization checks during the identifier assignment process.
CWE-285Improper Authorization1,500+Mandates authorization for identifier assignment, reducing risks of improper authorization.
CWE-286Incorrect User Management32Directly implements correct management of identifiers for individuals, groups, roles, services, and devices.
CWE-642External Control of Critical State Data18Requires authorization and prevents reuse, mitigating external control of critical identifier state data.
