Info

Web filter controls Web Filter If you have blocked a pattern but want certain users to have access to URLs within that pattern, you can use the Override within the FortiGuard Web Filter. This will allow you to specify which users have access to which blocked URLs and how long they have that access. For example, you want User1 to be able to access www.fakeLAND.com for 1 hour. You can use this section to set up the exemption. Any user listed in an override must fill out an online authentication form before the FortiGuard unit will grant access to the blocked URL. FortiGuard Web Filter also lets you create local categories to block groups of URLs. Once you have created the category, you can use the local rating to add specific sites to the local category you have created. You then use the Firewall > Protection Profile to tell the FortiGuard Unit what action to take with the Local category. The local ratings overwrite the FortiGuard ratings. Finally the FortiGuard unit applies script filtering for ActiveX, Cookie, and Java applet, which can be configured in Firewall > Protection Profile > Web Filtering. Once you have finished configuring all of these settings, you still have to turn them all on in the Firewall > Protection Profile > Web filtering and Firewall > Protection Profile >FortiGuard Web Filtering. By enabling them here, you are telling the FortiGate unit to start using the filters as you have configured them. This section describes how to configure web filtering options. Web filtering functions must be enabled in the active protection profile for the corresponding settings in this section to have any effect. Web filter controls As a general rule you go to Web Filter to configure the web filtering settings and to enable the filters for use in a protection profile. To actually activate the enabled filters you go to Firewall> Protection Profile. Note: Enabled means that the filter will be used when you turn on web filtering. It does not mean that the filter is turned on. To turn on all enabled filters you must go to Firewall> Protection Profile. FortiGuard - Web Filter is described in detail in“FortiGuard Web Filtering options” on page 334. Rating corrections as well as suggesting ratings for new pages can be submitted on the FortiGuard Center web page. Visit the Fortinet Knowledge Center for details and a link to the FortiGuard Center. The following tables compare web filtering options in protection profiles and the web filter menu. Table 37: Web filter and Protection Profile web content block configuration Protection Profile web filtering options Web Content Block Enable or disable web page blocking based on the banned words and patterns in the content block list for HTTP traffic. Web Filter setting Web Filter > Content Block Add words and patterns to block web pages containing those words or patterns. FortiGate Version 3.0 MR5 Administration Guide 424 01-30005-0203-20070830
