Web rating override

Web rating overrides allow you to add specific URLs to both FortiGuard and custom web ratings categories.

In a web filter profile, the action for each category can be configured. See FortiGuard filter for details. A web rating override in a custom category will not impact any web filters until the category's action is changed to Monitor, Block, Warning, or Authenticate in the specific web filter profile's settings. If a URL is in multiple enabled categories, the order of precedence is local categories, then remote categories, and then FortiGuard categories.

In SSL/SSH inspection profiles, custom categories must be explicitly selected to be exempt from SSL inspection. In proxy addresses, custom categories must be explicitly selected as URL categories for them to apply. In both settings, if a URL is in multiple selected categories, the order of precedence is local categories, then remote categories, and then FortiGuard categories.

Note

Web rating override requires a FortiGuard license.

Web filter profiles

In this example, www.fortinet.com is added to both a custom, or local, category (Seriously) and an external threat feed, or remote, category (OnAworkComputer). The local category action is set to Monitor, while the remote category action is set to Block. When a user browses to www.fortinet.com, the local category action takes precedence over both the remote category and the FortiGuard category (Information Technology), so the Monitor action is taken.

To create a custom category in the GUI:
  1. Go to Security Profiles > Web Rating Overrides.
  2. Click Custom Categories, then click Create New.
  3. Enter a name for the category, and ensure the Status is set to Enable.
  4. Click OK.
To create a web rating override in the GUI:
  1. Go to Security Profiles > Web Rating Overrides and click Create New.
  2. Enter the URL to override.
  3. Optionally, click Lookup rating to see what its current rating is, if it has one.
  4. For Category, select Custom Categories and for Sub-Category select the category previously created.

  5. Click OK.
To create a new FortiGuard category threat feed in the GUI:
  1. Go to Security Fabric > External Connectors and click Create New.

  2. In the Threat Feeds section, click FortiGuard Category.
  3. Enter a name for the threat feed, such as OnAworkComputer.
  4. Enter the URI of external resource.

  5. Configure the remaining settings as needed, then click OK.

To use the new categories in a web filter profile in the GUI:
  1. Go to Security Profiles > Web Filter and create or edit a web filter profile. See FortiGuard filter for more information.
  2. Enable FortiGuard category based filter
  3. Set the action for the Seriously category in the Local Categories group to Monitor.

  4. Set the action for the OnAworkComputer category in the Remote Categories group to Block.

    Note

    When the action for a custom category is Allow, the category is disabled. The next category's action in the order of preference will be applied.

  5. Configure the remaining settings are required, then click OK.
To use local and remote categories in a web filter profile in the CLI:
  1. Create the custom category and add a URL to it:
    config vdom
        edit root
            config webfilter ftgd-local-cat
                edit "Seriously"
                    set id 140
                next
            end
            config webfilter ftgd-local-rating
                edit "www.fortinet.com"
                    set rating 140
                next
            end
        next
    end
  2. Create a FortiGuard Category Threat Feed external connector to import an external blocklist.
    config global
        config system external-resource
            edit "OnAworkComputer"
                set category 192
                set resource "https://192.168.0.5/lists/blocklist.txt"
            next
        end
    end
  3. Enable the new category in a web filter profile. See FortiGuard filter for details.

    Custom local categories have an ID range of 140 to 191. Remote categories have an ID range of 192 to 221.

    config vdom
        edit root
            config webfilter profile
                edit "WebFilter-1"
                    set feature-set proxy
                    config ftgd-wf
                        unset options
                        config filters
                            edit 12
                                set category 12
                                set action warning
                            next
                            ...
                            edit 23
                                set action warning
                            next
                            edit 140
                                set category 140
                            next
                            edit 192
                                set category 192
                                set action block
                            next
                        end
                    end
                next
            end
        next
    end

    When a filter is added for the local and remote categories (140 and 192 in this example), the default action is monitor.
