With this firewall service, you can:
- Control traffic flowing into your server space. Traffic flows in and out through many different connections inside your hosting server. A firewall will close all connections and allow you to selectively open the connections from which you want to receive traffic.
- Prevent DDoS attacks. You don’t want a hacker to install a DDoS tool on your server. A firewall will prevent that from happening by closing outgoing ports, opening only those needed for authorized outgoing traffic.
- Track network connections. A firewall like CFS scans all network connections that pass through it and lets you know which ones made a suspicious number of failed login attempts.
Hope you enjoy it.
