NIST SP 800-53 Rev 5 NIST800-AC-5: Separation of duties
Requires the organization to identify and document the individual duties that must be kept apart to limit malevolent activity without collusion, and to define system access authorizations so that those duties cannot be exercised by one person.
What else in your programme already covers this
This control maps to 40 controls across 24 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
10.1.2 Requirement 10 roles and responsibilities documented and assigned
3.7.6 Manual cleartext key operations use split knowledge
7.2.2 Access is assigned to users, including privileged users, based on: • Job classification and function. • Least privileges necessary to perform job responsibilities
8.2.4 Addition, deletion, and modification of user IDs, authentication factors, and other identifier objects are managed as follows: • Authorized with the appropriate approval. • Implemented with only the privileges specified on the documented approval
6.5.4 Roles and functions are separated between production and pre-production environments to provide accountability such that only reviewed and approved changes are deployed
7.2.4 All user accounts and related access privileges, including third-party/vendor accounts, are reviewed as follows: • At least once every six months. • To ensure user accounts and access remain appropriate based on job function.
7.2.5 All application and system accounts and related access privileges are assigned and managed as follows: • Based on the least privileges necessary for the operability of the system or application. • Access is limited
8.6.1 If accounts used by systems or applications can be used for interactive login, they are managed as follows: • Interactive use is prevented unless needed for an exceptional circumstance. • Interactive use is limited
NIST-CSF-PR.AA-05 Access permissions, entitlements, and authorizations are defined in a policy, managed, enforced, and reviewed, and incorporate the principles of least privilege and separation of duties
You are reading one control. How much of NIST SP 800-53 Rev 5 have you already done?
NIST SP 800-53 Rev 5 NIST800-AC-5 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of NIST SP 800-53 Rev 5 your existing evidence covers. Hold ISO 27001:2022 and 163 of 300 NIST SP 800-53 Rev 5 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 342 were rejected on the ISO 27001:2022 pair alone.
