Firewall Watchdog Script
Well, if you are like me, one day, while adding a new rule or making
a change to your firewall, you will forget and leave it off. This situation
could go undetected for months allowing someone to easily enter your
site. To prevent this, I've written a simple script that checks that
the firewall is turned on. If you place it in your /etc/cron.hourly
file, and you leave your firewall off, you will get an email message (assuming
that you are running my firewall script and that you receive mail from
root).
Note, the download contains firewall, masquerade, and check.firewall.hourly.
