Rule Text

Amazon Linux 2023 audit log directory must be owned by root to prevent unauthorized read access.

Description

Discussion Text

Unauthorized disclosure of audit records can reveal system and configuration data to attackers, thus compromising its confidentiality. Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit operating system activity. Satisfies: SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029, SRG-OS-000206-GPOS-00084

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.

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 [ ! -d "/etc/audit/auditd.conf" ]; then echo "PASS"; exit 0; fi
if [ "$(stat -c "%u" /var/log/audit)" != "0" ]; then echo "FAIL"; exit 1; fi
echo "PASS"
exit 0

Remediation

Configure Amazon Linux 2023 so that the audit logs directory is protected from unauthorized read access by setting the correct owner as "root" with the following command:

$ sudo chown root /var/log/audit
