Ensure only authorized users own audit log files

HighLevel 2Automatedfreebsd

Description

Audit log files contain information about the system and system activity. Access to audit records can reveal system and configuration data to attackers, potentially compromising its confidentiality. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

How it is checked

Audit method: Shell command

shell

command -v find >/dev/null 2>&1 || exit 1; d=$(awk -F: '/^dir:/ {print $2; exit}' /etc/security/audit_control 2>/dev/null); [ -n "$d" ] && [ -d "$d" ] || exit 1; out=$( { find "$d" -type f ! -user root -exec stat -Lf "%N %Su" {} + ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Run the following command to configure the audit log files to be owned by the root user: # [ -f /etc/security/audit_control ] && find "$(awk -F ":" '/^dir/ {print $2}' /etc/security/audit_control | xargs)" -type f ! -user root -exec chown root {} +
