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 238 .
This chapter describes:
