URL Filtering Administration

When administering the URL filtering process, you can use several configuration items that are available by default.

  • URL Filtering rule set — Default rule set for URL filtering
    This rule set includes two nested rule sets, which allow you to run the default URL filtering process on Web Gateway in two different ways.
    • Special URL Filtering Group rule set — Nested rule set for performing URL filtering with regard to particular users, user groups, and IP addresses.

      The rule set includes a blocking rule and whitelisting rules. Further rules ensure a high level of filtering quality.

      For example, one rule requires that the complete body of a web object is scanned for infections, even if only a request for accessing the object in parts was submitted.
       
    • Default rule set — Nested rule set for performing URL filtering in general, regardless of any particular users, user groups, or IP addresses

      The rule set includes a blocking rule and whitelisting rules. Further rules ensure a high level of filtering quality.

      For example, one rule requires that the complete body of a web object is scanned for infections, even if only a request for accessing the object in parts was submitted.
       
  • Whitelists and blocking lists — Used to allow and block access to web objects with particular URLs
    • URL Whitelist — Lists URLs. Use this list to exclude requests for access to web objects with particular URLs from further URL filtering.

      This way you ensure that users are not prevented from accessing these objects by URL filtering

      The list is empty by default and you need to fill the entries.
       
    • URL Blocklist — List user agents. Use this list to exclude requests with particular user agent information in its headers from further anti-malware filtering.

      The list is empty by default and you need to fill the entries.
       
    • Category Blocklist — List user agents. Use this list to exclude requests with particular user agent information in its headers from further anti-malware filtering.

      The list is empty by default and you need to fill the entries.
       
  • Blocklists — Used to exclude web objects from further anti-malware filtering
    • URL Host Whitelist — Lists the URLs of hosts. Use this list to exclude requests with particular URLs from further anti-malware filtering.

      The list is empty by default and you need to fill the entries.
       
    • User Agent Whitelist — List user agents. Use this list to exclude requests with particular user agent information in its headers from further anti-malware filtering.

      The list is empty by default and you need to fill the entries.
       
  • URL Filter settings — Default settings for the URL Filter module

    An option is selected in these settings that enables the Skyhigh Security Gateway Anti-Malware (GAM) engine for scanning web objects.

    You can change these settings, for example, to involve the Avira engine in the scanning process.

    You can also create your own rule set, lists, and settings for URL filtering.
