IA-13Identity Providers and Authorization Servers

Employ identity providers and authorization servers to manage user, device, and non-person entity (NPE) identities, attributes, and access rights supporting authentication and authorization decisions in accordance with {{ insert: param, ia-13_odp.01 }} using {{ insert: param, ia-13_odp.02 }}.

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 Authorization9,346Requiring authorization servers ensures authorization is performed for protected functions.
CWE-284Improper Access Control5,367Authorization servers centrally manage access rights, preventing improper access control.
CWE-287Improper Authentication4,908Identity providers centralize and enforce authentication mechanisms, reducing improper authentication.
CWE-863Incorrect Authorization3,515Centralized authorization servers reduce incorrect authorization by enforcing consistent policies.
CWE-306Missing Authentication for Critical Function2,820Identity providers mandate authentication for functions that would otherwise lack it.
CWE-798Use of Hard-coded Credentials2,013External identity providers eliminate the need for hard-coded credentials in applications.
CWE-285Improper Authorization1,356Dedicated authorization servers support policy-based decisions, mitigating improper authorization.
CWE-288Authentication Bypass Using an Alternate Path or Channel592Centralized IdPs close alternate authentication paths that enable bypass.
