URL Filtering Using the Dynamic Content Classifier

URLs can be categorized for filtering by the Dynamic Content Classifier.

The Dynamic Content Classifier (DCC) is another source of category information with regard to URLs, in addition to the local database and the Global Threat Intelligence service.

You can configure use of the Dynamic Content Classifier when lookups for URL category information involving the other two sources yield no results.

Configure use of the Dynamic Content Classifier

You can configure use of the Dynamic Content Classifier for detecting URL categories when other methods of detection yield no results.

  1. Select Policy | Rule Sets.
  2. On the rule sets tree, select a rule set with rules for URL filtering.
    In the default rule set system, this is, for example, the URL Filtering rule set.
    The rules appear in the settings pane.
  3. Make sure Show details is selected.
  4. Select the rule for handling URL categories that you want to configure use of the Dynamic Content Classifier for.
    In the URL Filtering rule set, this is, for example, the rule Block URLs whose category is in Category BlockList.
  5. Click the settings of the URL Filter module in the rule criteria.
    In the sample rule, these are the Default settings in the criteria URL.Categories <Default> at least one in list Category BlockList.
    The Edit Settings window opens. It provides the settings of the URL Filter module.
  6. Under Rating Settings, make sure Enable the Dynamic Content Classifier if GTI web categorization yields no results is selected.
  7. [Optional] Edit the list of URL categories the Dynamic Content Classifier should detect.
    1. Above the list Categories that will be dynamically detected, click the Edit icon.
      The Edit window opens.
    2. Under DCC category, expand the Supported Categories folder.
    3. Select or deselect URL categories as needed.
    4. Click OK.
      The Edit window closes and the selected categories appear on the list.
      NOTE: You can remove a URL category from the list by clicking the Delete symbol and confirming in the window that opens.

  9. Click Save Changes.

The Dynamic Content Classifier is now involved in detecting whether a URL that is submitted in a request for web access falls into one of the configured URL categories.
