Hi,

Take a look to this reference

Hacker, exploiters, phreakers, etc, etc are reals. Try to secure your network, specially if you handle sensible data (ex. customers info, accounts, etc).

Add firewalls, Web App Firewalls, vlan, and other security to your network. Is not good idea to have your FS host machine connected directly to internet relaying in basic protection.
