ℹ️ Check
Verify the audit log directory has 0700 (u=rwx) permissions. First determine where the audit logs are stored with the following command: $ grep -w log_file /etc/audit/auditd.conf log_file = /var/log/audit/audit.log Then using the location of the audit log file, determine if the audit log directory has 0700 permissions using the following command: $ stat -c "%U:%G %#a %n" /var/log/audit root:root 0700 /var/log/audit If the audit log directory does not have 0700 permissions, this is a finding.
