# Add Inspection rules

Inspection rules filter traffic based on traffic patterns. Inspection rules are stored in Inspection Policy elements.

## Before you begin

You must have a custom Policy element and permissions to edit it.

##

The rules tree on the Inspection tab is the main tool that allows you to select which traffic patterns are permitted and stopped. You can also select whether a log entry or an alert is triggered, and whether matching traffic is recorded.

The rules table on the Exceptions table allows you to define detailed exceptions to the Inspection rule. The main uses for Exceptions are to eliminate false positives and to activate block listing or User Responses for specific traffic patterns.

Note: For layer 2 physical interfaces on Security Engines in the Engine/VPN role, you select the Inspection Policy in the Engine Policy.
