The configuration of Web content filtering for flying Tower firewall

Description

This document describes the Web content filtering configuration for all fortigate devices. FortiGate can identify and filter Web pages that contain certain words. Web content filtering is one of the most effective ways to restrict a user's access to a particular type of Web site. This document illustrates the specific use of this feature by blocking the stock page. Web pages that block other content are similarly.

Environment Introduction:

This article uses fortigate400a to do the demo. The system version supported in this article is Fortios v3.0 and higher.

Step one: Create a new page content filter List

New content Blocking List < in Web filter----content blocking

Step two: Define the content of the filter

Then click on the new definition of blocked content

Style: Input blocked vocabulary

Pattern type: Selecting wildcard characters

Language: Choose what language you want to block

Score: Define the value of the content

Activate: tick the defined content

Note: This example defines seven stock-related terms, each score is 2, and the threshold is set to 8 in the Content Protection table. First, fortigate the number of words in the scanned web page to match the defined block words, and then adds a block to the lexical score, blocking the page if the total score is greater than or equal to the threshold value. That is, if the page contains more than (or equal to) four block words, the page is considered a stock page. Block the number of words, vocabulary points and the protection of the content table threshold can be set according to the actual situation. <

Repeat the above method to define multiple stock-related lexical scores for 2<
