ACF2 PPGM GSO record value must specify protected programs that are only executed by privileged users.

Rule version ACF2-ES-000390 · STIG v9 · 2026-09-01

Discussion

Preventing non-privileged users from executing privileged functions mitigates the risk that unauthorized individuals or processes may gain unnecessary access to information or privileges.

Privileged functions include, for example, establishing accounts, performing system integrity checks, or administering cryptographic key management activities. Non-privileged users are individuals that do not possess appropriate authorizations. Circumventing intrusion detection and prevention mechanisms or malicious code protection mechanisms are examples of privileged functions that require protection from non-privileged users.

Check

From the ACF command screen enter: SET CONTROL(GSO) LIST LIKE(PPGM-)
