Module for URL filtering Web filtering URL filtering 6 You can configure the module for URL filtering to let it retrieve information on URLs in different ways. This section explains how this is done and describes the module settings. The name of the module for URL filtering is URL Filter. It is also known as URL Filter engine. When this module is called by a URL filtering rule to retrieve information on particular URLs, it connects to the Global Threat Intelligence (GTI) system. This system provides information on categories and reputation scores for URLs, based on the content of the corresponding web pages. Various technologies, such as link crawlers, security forensics, honeypot networks, sophisticated auto-rating tools, and customer logs are used to gather this information. An international, multi-lingual team of McAfee web analysts evaluates the information and enters URLs under particular categories into a database. To gather information on the reputation of a URL, its behavior on a worldwide real-time basis is analyzed, for example, where a URL shows up in the web, its domain behavior, and other details. Configure the URL Filter module To configure settings for the URL Filter module: 1 Go to Policy | Rule Sets. 2 On the rule sets tree, select the rule set that contains rules for URL filtering. The rules appear on the settings pane. 3 Find the rule that uses a category blocking list, for example, Block URLs whose category is in Category BlockList. The settings of the URL filter module appear within the rule criteria next to the URL.Categories property. Their name is, for example, Default. 4 Click on the settings name. The Edit Settings window opens. 5 Configure these settings as needed. 6 Click Save Changes. For more information on these settings, see Settings for the URL Filter module. Settings for the URL Filter module This section describes the settings for the URL Filter module, which is the module that retrieves information from the Global Threat Intelligence system.
