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.
The Firewall Options policy allows you enable or disable the firewall and to apply an Adaptive mode or Learn mode to agents to facilitate creation of firewall rules for your corporate environment. In automatic Adaptive mode and interactive Learn mode, Host Intrusion Prevention creates rules whenever it detects unknown network traffic.
Use any of the several predefined Firewall Rules policies or create custom policies. Rules created on clients through Adaptive and Learn mode can be added to custom policies and enforced as administrative rules.
The Quarantine Options policy lists networks on which to enforce quarantine and what to do when the quarantine update check fails.
The Quarantine Rules policy is a restrictive firewall rules policy enforced when clients are quarantined.
