Check Text (C-248732r958434_chk)
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 Text (F-52120r779761_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".
