Assessment Title

Rule Text

System audit logs must be group-owned by root, bin, or sys.

Description

Discussion Text

Sensitive system and user information could provide a malicious user with enough information to penetrate further into the system.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

Determine the location of audit logs and then check the group-ownership.

Procedure:
# more /etc/security/audit_control
# ls -lLd <audit log dir>

If any audit log file is not group-owned by root, bin, or sys, this is a finding.

SCC Automation Reference

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

    if [ -e "$file" ]; then
        if [ "$(stat -c "%G" "$file")" = "root" ] || [ "$(stat -c "%G" "$file")" = "bin" ] || [ "$(stat -c "%G" "$file")" = "sys" ]; then echo "PASS"; exit 0; fi
    fi
done
echo "FAIL"; exit 1

Remediation

Change the group ownership of the audit log file(s).

Procedure:
# chgrp root <audit log file>
