FortiOS 6 – Web Filtering

To configure the FortiGuard Web Filter categories

  1. Go to the Edit Web Filter Profile
  2. The category groups are listed in a widget. You can expand each category group to view and configure every subcategory individually within the groups. If you change the setting of a category group, all categories within the group inherit the change.
  3. Select the category groups and categories to which you want to apply an action.

To assign an action to a category left click on the category and select from the pop up menu.

  1. Select Apply or OK.

Apply the web filter profile to an identity-based security policy. All the users subject to that policy are restricted by the quotas.

If you look at your logs carefully, you may notice that not every URL connection in the log shows a category. They are left blank. If you take one of those URL and enter it in the FortiGuard website designed to show the category for a URL it will successfully categorize it.

The reason for this is that to optimize speed throughput and reduce the load on the FortiGuard servers the FortiGate does not determine a category rating on scripts and css files.

  1. Go to the Edit Web Filter Profile window
  2. Verify that the categories that need to have quotas on them are set to one of these actions:
    • Monitor l Warning l Authenticate

  4. In the New/Edit Quota window that pops up, enable or disable the specific categories for that quota.
  5. At the bottom of the widget, select a quota type and daily allowance for each user:
    • Time — can be entered in Hours, Minutes, or Seconds.
    • Traffic — can be entered in Bytes, KB, MB, or GB The value must be greater than 0.
  6. Select Apply or OK.
  7. Continue with any other configuration in the profile Select Apply or OK.

Apply the web filter profile to an identity-based security policy. All the users subject to that policy are restricted by the quotas.

The use of FortiGuard Web Filtering quotas requires that users authenticate to gain web access. The quotas are ignored if applied to a security policy in which user authentication is not required.
