Chapter 36 Content Filtering
ZyWALL/USG Series User’s Guide
632
The following table describes the managed categories.
Malware Sites that install unwanted software on a user's computer with the intent to
enable third-party monitoring or make system changes without the user's
consent. For example, www.tqlkg.com, aladel.net.
Network Errors Sites that do not resolve to any IP address.
Parked Domains Sites that are inactive, typically reserved for later use. They most often do not
contain their own content, may simply say "under construction," "purchase
this domain," or display advertisements. For example, www.moemoon.com,
artlin.net, img.sedoparking.com.
Phishing & Fraud Sites that are used for deceptive or fraudulent purposes (e.g. phishing), such
as stealing financial or other user account information. These sites are most
often designed to appear as legitimate sites in order to mislead users into
entering their credentials. For example, optimizedby.rmxads.com,
218.1.71.226/.../e3b.
Spam Sites Sites that have been promoted through spam techniques. For example,
img.tongji.linezing.com, banner.chinesegamer.net.
Managed Categories These are categories of web pages based on their content. Select categories in
this section to control access to specific types of Internet content.
You must have the Category Service content filtering license to filter these
categories. See the next table for category details.
Test Web Site Category
URL to test You can check which category a web page belongs to. Enter a web site URL in
the text box.
When the content filter is active, you should see the web page’s category. The
query fails if the content filter is not active.
Content Filtering can query a category by full URL string (for example, http://
www.google.com/picture/index.htm), but HTTPS Domain Filter can only query
a category by domain name ('www.google.com'), so the category may be
different in the query result. URL to test displays both results in the test.
