IA-13 Identity Providers and Authorization Servers
Control
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 [Assignement: policy] using [Assignement: mechanisms].
Discussion
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.
Assessment Objective
- identity providers are employed to manage user, device, and non-person entity (NPE) identities, attributes and access rights supporting authentication decisions in accordance with [Assignement: mechanisms] using [Assignement: mechanisms];
- identity providers are employed to manage user, device, and non-person entity (NPE) identities, attributes and access rights supporting authorization decisions in accordance with [Assignement: mechanisms] using [Assignement: mechanisms];
- authorization servers are employed to manage user, device, and non-person entity (NPE) identities, attributes and access rights supporting authentication decisions in accordance with [Assignement: mechanisms] using [Assignement: mechanisms];
- authorization servers are employed to manage user, device, and non-person entity (NPE) identities, attributes and access rights supporting authorization decisions in accordance with [Assignement: mechanisms] using [Assignement: mechanisms];
Assessment Method

IA-13(01) Protection of Cryptographic Keys
|
Control
Cryptographic keys that protect access tokens are generated, managed, and protected from disclosure and misuse.
Discussion
Identity assertions and access tokens are typically digitally signed. The private keys used to sign these assertions and tokens are protected commensurate with the impact of the system and information resources that can be accessed.
Assessment Objective
- cryptographic keys that protect access tokens are generated;
- cryptographic keys that protect access tokens are managed;
- cryptographic keys that protect access tokens are protected from disclosure; and
- cryptographic keys that protect access tokens are protected from disclosure and misuse
Assessment Method
Examine
Identification and authentication policy;
procedures addressing cryptographic key establishment and management;
system design documentation;
cryptographic mechanisms;
system configuration settings and associated documentation;
system security plan;
other relevant documents or records
Interview
System/network administrators;
organizational personnel with information security responsibilities;
organizational personnel with responsibilities for cryptographic key establishment and/or management

IA-13(02) Verification of Identity Assertions and Access Tokens
|
Control
The source and integrity of identity assertions and access tokens are verified before granting access to system and information resources.
Discussion
This includes verification of digital signatures protecting identity assertions and access tokens, as well as included metadata. Metadata includes information about the access request such as information unique to user, system or information resource being accessed, or the transaction itself such as time. Protected system and information resources could include connected networks, applications, and APIs.
Assessment Objective
- the source of identity assertions is verified before granting access to system and information resources;
- the source of access tokens is verified before granting access to system and information resources;
- the integrity of identity assertions is verified before granting access to system and information resources;
- the integrity of access tokens is verified before granting access to system and information resources
Assessment Method
Examine
Identification and authentication policy;
system security plan; system design documentation;
system configuration settings and associated documentation;
other relevant documents or records
Interview
Organizational personnel with system operations responsibilities;
organizational personnel with information security responsibilities;
system/ network administrators;

IA-13(03) Token Management
|
Control
In accordance with [Assignement: policy], assertions and access tokens are:- generated;
- issued;
- refreshed;
- revoked;
- time-restricted; and
- audience-restricted.
Discussion
An access token is a piece of data that represents the authorization granted to a user or NPE to access specific systems or information resources. Access tokens enable controlled access to services and resources. Properly managing the lifecycle of access tokens, including their issuance, validation, and revocation, is crucial to maintaining confidentiality of data and systems. Restricting token validity to a specific audience, e.g., an application or security domain, and restricting token validity lifetimes are important practices. Access tokens are revoked or invalidated if they are compromised, lost, or are no longer needed to mitigate the risks associated with stolen or misused tokens.
Assessment Objective
- assertions are generated in accordance with [Assignement: policy];
- access tokens are generated in accordance with [Assignement: policy];
- assertions are issued in accordance with [Assignement: policy];
- access tokens are issued in accordance with [Assignement: policy];
- assertions are refreshed in accordance with [Assignement: policy];
- access tokens are refreshed in accordance with [Assignement: policy];
- assertions are revoked in accordance with [Assignement: policy];
- access tokens are revoked in accordance with [Assignement: policy];
- assertions are time-restricted in accordance with [Assignement: policy];
- access tokens are time-restricted in accordance with [Assignement: policy];
- assertions are audience-restricted in accordance with [Assignement: policy];
- access tokens are audience-restricted in accordance with [Assignement: policy];
Assessment Method

Identification and authentication policy;
access control policy;
procedures for assertion and token management;
system design documentation;
system configuration settings and associated documentation;
other relevant documents or records
Interview
