Configuring the Content Filtering to Control Access to Internet

STEP 3 Click Save to apply your settings.
Configuring the Content Filtering to Control Access to Internet
The Content Filtering feature provides protection against websites. It blocks or
allows web access based on analysis of its content (URL or URL keywords), rather
than its source or other criteria. It is most widely used on the Internet to filter the
web access.
The Content Filtering policy profile assigned to each zone determines whether to
block or forward the HTTP request from the hosts in the zone. The blocked
request will be logged.
This section includes the following topics:
• Configuring the Content Filtering Policy Profiles, page 201
• Configuring the Website Access Control List, page 203
• Mapping the Content Filtering Policy Profiles to Zones, page 204
• Configuring Advanced Settings, page 204
!
CAUTION Enabling the Web URL Filter service will disable the firewall content filtering
settings.
Configuring the Content Filtering Policy Profiles
A Content Filtering policy profile is used to specify the websites to be blocked or
permitted.
NOTE The security appliance supports up to 16 content filtering policy profiles.
STEP 1 Click Firewall -> Content Filtering -> Content Filtering Policy.
The Content Filtering Policy window opens.
