Web filtering
Web filtering is enabled in firewall policies. When you enable Anti-Virus & Web filter in
a firewall policy, you select a content profile that controls how web filtering behaves for
HTTP traffic. Content profiles control the following types of content filtering:
• blocking unwanted URLs,
• blocking unwanted content,
• removing scripts from web pages,
• exempting of URLs from blocking.
You can also use the Cerberian URL blocking to block unwanted URLs. For more
information, see “Using the Cerberian web filter” on page 212.
This chapter describes:
