Firewall

The Firewall guards the "doors" to your devices, that is, the ports through which Internet traffic comes in and goes out.

It examines all the network traffic and application traffic arriving at your device, and asks these questions:

• Where did the traffic come from and what port is it addressed to?

• Do the firewall rules allow traffic through that port?

• Does the traffic violate any global rules?

The answers to these questions determine whether the traffic is allowed or blocked.

When you plan a Firewall Policy, think about the security of your network and convenience for your users.

A policy must let users work as freely as possible, but also reduce the threat of attack from malicious third parties.

Firewall rules accept or drop network traffic to and from Endpoint computers, based on connection information, such as IP addresses, Domains, ports and protocols.
