Viewing the web content exempt list catalog
You can add multiple web content exempt lists and then select the best web content
exempt list for each protection profile.
To view the web content block list catalog go to UTM > Web Filter > Web Content Exempt.
To view any individual web content exempt list, select the Edit icon for the list you want to
see.
Figure 308: Sample web content exempt list catalog
The web content exempt list catalogue has the following icons and features:
Banned Word Enter the content block pattern. For a single word, the FortiGate checks all
web pages for that word. For a phrase, the FortiGate checks all web pages
for any word in the phrase. For a phrase in quotation marks, the FortiGate
unit checks all web pages for the entire phrase.
Pattern Type Select a pattern type from the dropdown list: Wildcard or Regular
Expression.
Language Select a language from the dropdown list.
Score Enter a score for the pattern.
Each entry in the web content block list incudes a score. When you add a
web content block list to a protection profile you configure a web content
block threshold for the protection profile.
When a web page is matched with an entry in the content block list the
score is recorded. If a web page matches more than one entry the score for
the web page increases. When the total score for a web page equals or
exceeds the threshold the page is blocked.
The default score for a content block list entry is 10 and the default
threshold is 10. This means that by default a web page is blocked by a
single match. You can change the scores and threshold so that web pages
can only be blocked if there are multiple matches. For more information,
see “Web Filtering options” on page 411.
Enable Select to enable the pattern.
Create New Select to add a new web content exempt list to the catalog.
Name The available web content block lists.
# Entries The number of content patterns in each web content block list.
Profiles The protection profiles each web content block list has been applied to.
