AC-24(02) No User or Process Identity

NIST SP 800-53 (controls) 5.2.0 against 5.2.0
All changes in this version
unchanged AC part of AC-24

Title

No User or Process Identity

Control

Enforce access control decisions based on [Assignment: organization-defined security or privacy attributes] that do not include the identity of the user or process acting on behalf of the user.

Discussion

In certain situations, it is important that access control decisions can be made without information regarding the identity of the users issuing the requests. These are generally instances where preserving individual privacy is of paramount importance. In other situations, user identification information is simply not needed for access control decisions, and especially in the case of distributed systems, transmitting such information with the needed degree of assurance may be very expensive or difficult to accomplish. MAC, RBAC, ABAC, and label-based control policies, for example, might not include user identity as an attribute.

Parameters

ac-24.2_prm_1: organization-defined security or privacy attributes
ac-24.02_odp.01: security attributes
ac-24.02_odp.02: privacy attributes
