Description
Service configuration files enable or disable features of their respective services that if configured incorrectly can lead to insecure and vulnerable configurations; therefore, service configuration files must have the correct access rights to prevent unauthorized changes.
ℹ️ Check
Verify that OL 9 configures permissions of /etc/crontab with the following command:
$ stat -c "%a %n" /etc/crontab
0600
If /etc/crontab does not have a mode of "0600", this is a finding.
✔️ Fix
Configure the OL 9 file /etc/crontab with mode 600.
$ sudo chmod 0600 /etc/crontab
