Blocking or monitoring Web sites using the blacklist
You can block or monitor specific Web sites by adding them to the blacklist. When you add a Web site to the blacklist, it affects all policies. If a URL access occurs that matches the blacklist entry, Symantec Web Gateway checks for a matching policy for the computer. The Spyware Severity and Spyware Category in the matching policy determine the action that Symantec Web Gateway takes.
You can also block and monitor specific Web sites for a single policy using content filter exceptions. The default setting in the monitoring mode is to monitor. Because they act on single policies only, content filter exceptions provide a more targeted method of blocking and monitoring Web sites. You need the URL filtering license to configure content filter exceptions. You do not need the URL filtering license to block or monitor Web sites with blacklists.
Symantec Web Gateway supports custom blacklist policies over HTTPS. It is unsupported over SSL Deep Inspection.
You can also add blacklist entries from a text file. You assign the same Category and Severity for all domain names and IP addresses in the file.
List one domain name or IP address per line in the file. You can optionally add one or more keywords to the file. Separate keywords from the domain name with a comma. You should separate multiple keywords with spaces.
Type a Name for the blacklist entry.
The name appears on the blacklist page and in reports.
For Block Type, click Block by URL.
For Domain or IP, type the Web site domain name or IP address.
For example, type www.example.com to monitor or block all URLs that start with www.example.com. Use an asterisk as a wildcard for part of the domain. For example, type *.example.com to match URLs that start with example.com, www.example.com, and mail.example.com. Omit the http:// part of a URL. Omit any part of a URL other than the domain name.
For Keyword you can optionally type a partial URL to associate with the domain specified in Domain or IP.
For example, if you type warez, the following URLs would match: www.example.com/warez/index.html and www.example.com/folder/warez.html.
The asterisk wildcard is not valid for Keyword. Omit slashes in the Keyword.
For Description, type a description.
The Description appears on the blacklist page and in reports.
Click a Severity.
The blacklist Severity relates to the policy Spyware Severity. The action that you set for Spyware Severity in a matching policy applies to the blacklist entry. The Severity is also recorded and used in reports.
Click a Category.
The blacklist Category relates to the policy Spyware Category. The action that you set for Spyware Category in a matching policy applies to the blacklist entry. In addition to the predefined categories, you can assign the URL to one of the three Custom Restricted Lists. The Category is also recorded and used in reports.
