CVE-2023-27312

Policy promotes least privilege by defining necessary privileges and management commitment to them.

Supervision detects and allows removal of unnecessary privileges that enable execution with excess rights.

Reviewing accounts for compliance, disabling/removing unneeded accounts, and aligning with termination processes prevents execution with unnecessary privileges.

Separation of duties prevents any single user from holding all privileges needed to complete a critical task, directly reducing execution with unnecessary privileges.

Directly prevents execution with more privileges than needed for assigned tasks.

Role-based training on least privilege principles reduces the chance personnel assign or retain unnecessary privileges.

Analysis of audit records can identify execution with unnecessary privileges through unusual activity patterns.

Automatic termination after a defined period eliminates unnecessary privileges from persistent connections.

A.5.15's policy, requirements, and rules for determining/minimizing access rights (incl. privileged access restrictions, need-to-know, least-privilege-like mapping, and role-based consistency) directly stop most unnecessary-privilege execution by design; bounded remainder is runtime elevation or misconfigured enforcement that still requires other controls (e.g. 8.2, 8.3) to act.

Requiring explicit justification and time-limited grants discourages the routine allocation of unnecessary privileges that would otherwise allow execution with more rights than required.

Independent scrutiny can identify processes or services still running with unnecessary privileges and drive their reduction before an attacker can abuse them.
