Vulnerability Discussion
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.

Check
Verify the audit logs have a mode of "0600" or less permissive.
Determine where the audit logs are stored with the following command:
$ sudo grep -iw log_file /etc/audit/auditd.conf
log_file = /var/log/audit/audit.log
Using the location of the audit log file, determine if the audit log has a mode of "0600" or less permissive with the following command:
$ sudo stat -c "%a %n" /var/log/audit/audit.log
600 /var/log/audit/audit.log
If the audit log has a mode more permissive than "0600", this is a finding.
Fix
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".
