Control Statement
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 [Assignment: organization-defined policy] using [Assignment: organization-defined mechanisms].
Supplemental Guidance
Identity providers, both internal and external to the organization, manage the user, device, and NPE authenticators and issue statements, often called identity assertions, attesting to identities of other systems or systems components. Authorization servers create and issue access tokens to identified and authenticated users and devices that can be used to gain access to system or information resources. For example, single sign-on (SSO) provides identity provider and authorization server functions. Authenticator management (to include credential management) is covered by IA-05.
Control Enhancements

Baseline(s):
Cryptographic keys that protect access tokens are generated, managed, and protected from disclosure and misuse.
IA-13(2): Verification of Identity Assertions and Access Tokens
Baseline(s):
The source and integrity of identity assertions and access tokens are verified before granting access to system and information resources.
IA-13(3): Token Management
Baseline(s):
In accordance with [Assignment: organization-defined policy], assertions and access tokens are: generated; issued; refreshed; revoked; time-restricted; and audience-restricted.
