About Default Threat Protection
With default threat protection, a firewall examines the source and destination of each packet it receives. It looks at the IP address and port number and monitors the packets to look for patterns that show your network is at risk. If a risk exists, you can configure the Firebox to automatically block a possible attack. This proactive method of intrusion detection and prevention keeps attackers out of your network.

You can also purchase an upgrade for your Firebox to use signature-based intrusion prevention. For more information, see About Gateway AntiVirus.
