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.

Verify the audit log files have 0600 (u=rw-) 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 logs have 0600 permissions using the following command:

$ stat -c "%U:%G %#a %n" /var/log/audit/*

root:root 0600 /var/log/audit/audit.log

If the audit log files do not have 0600 permissions, this is a finding.
