Check Text (C-258165r958434_chk)
Verify the audit logs are group-owned by "root" or a restricted logging group.
First determine if a group other than "root" has been assigned to the audit logs with the following command:
$ sudo grep log_group /etc/audit/auditd.conf
Then 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
Then using the location of the audit log file, determine if the audit log is group-owned by "root" using the following command:
$ sudo stat -c "%G %n" /var/log/audit/audit.log
root /var/log/audit/audit.log
If the audit log is not group-owned by "root" or the configured alternative logging group, this is a finding.
Fix Text (F-61830r926481_fix)
Change the group of the directory of "/var/log/audit" to be owned by a correct group.
Identify the group that is configured to own audit log:
$ sudo grep -P '^[ ]*log_group[ ]+=.*$' /etc/audit/auditd.conf
Change the ownership to that group:
$ sudo chgrp ${GROUP} /var/log/audit
