Content Filtering Configuration Overview

Content security filter is a new feature that blocks or allows certain type of traffic base on the mime type, file extension, protocol commands and embedded object type. The content filter controls file transfers across the gateway by checking traffic against configured filter lists. The content filtering module evaluates traffic before all other UTM modules, if traffic meets the criteria configured in the content filter, the content filter acts first upon this traffic. The following procedure lists the recommended order in which you should configure content filters:

1. Configure UTM custom objects for the feature. See Example: Configuring Content Filtering Custom Objects.

2. Configure the main feature parameters using feature profiles. See Example: Configuring Content Filtering Feature Profiles.
3. Configure a UTM policy for each protocol and attach this policy to a profile. See Example: Configuring Content Filtering UTM Policies.
4. Attach the UTM policy to a security policy. See Example: Attaching Content Filtering UTM Policies to Security Policies.
