Description
If modification of login UIDs is not prevented, they can be changed by nonprivileged users and make auditing complicated or impossible. Satisfies: SRG-OS-000462-GPOS-00206, SRG-OS-000475-GPOS-00220, SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029

Who does this work

12 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-274187r1120715_chk)

Verify Amazon Linux 2023 is configured so that the audit system prevents unauthorized changes to login UIDs with the following command: $ sudo grep -i immutable /etc/audit/audit.rules --loginuid-immutable If the "--loginuid-immutable" option is not returned in the "/etc/audit/audit.rules", or the line is commented out, this is a finding.

Fix Text (F-78183r1120548_fix)

Configure Amazon Linux 2023 auditing to prevent modification of login UIDs once they are set by adding the following line to /etc/audit/rules.d/audit.rules: --loginuid-immutable To load the rules to the kernel immediately, use the following command: $ sudo augenrules --load
