Check Text ( C-33067r567940_chk )
Verify the audit logs are group-owned by "root". First 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 is group-owned by "root" using the following command:

$ sudo ls -al /var/log/audit/audit.log

rw------- 2 root root 23 Jun 11 11:56 /var/log/audit/audit.log

If the audit log is not group-owned by "root", this is a finding.
Fix Text (F-33042r567941_fix)
Configure the audit log to be owned by root by configuring the log group in the /etc/audit/auditd.conf file:

log_group = root
