5Firewall Policies

The Firewall feature of Host Intrusion Prevention protects computers by filtering all network traffic, allowing legitimate traffic through the firewall and blocking the rest. This is done by applying firewall rules. In the current release of the product, stateful filtering and inspection have been added to manage version 6.1 clients. Legacy static firewall rules, referred to as HIP 6.0 rules, are also available but apply only to version

6.0clients. To aid in the transition from static to stateful rules, a firewall rules migration utility is available.

This section describes the Firewall feature and includes the following topics:
