Check Text (C-270827r1066970_chk)
Verify that the audit log files 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 path of the directory containing the audit logs, determine if the audit log files have a mode of "0600" or less with the following command:
$ sudo stat -c "%n %a" /var/log/audit/*
/var/log/audit/audit.log 600
If the audit log files have a mode more permissive than "0600", this is a finding.
