Assessment Title

Rule Text

OL 8 audit logs must have a mode of "0600" or less permissive 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 OL 8 activity. Satisfies: SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029

log_file=$(grep -E '^log_file\\s*=\\s*(\S+)' /etc/audit/auditd.conf | cut -d= -f2-) && [ -n "$log_file" ] || log_file="/var/log/audit/audit.log"
if [ ! -f "$log_file" ]; then echo "PASS"; exit 0; fi
mode=$(stat -c "%a" "$log_file")
if [ "$mode" -le 600 ]; then echo "PASS"; exit 0; else echo "FAIL"; exit 1; fi

Remediation

Configure the audit log to be protected from unauthorized read access by setting the correct permissive mode with the following command: 
 
$ sudo chmod 0600 [audit_log_file] 
 
Replace "[audit_log_file]" to the correct audit log path. By default, this location is "/var/log/audit/audit.log".
