7.3 Configuring URL Filtering Lists
Lists are categorized lists of websites, maintained externally to WebMarshal. You can use the categories provided by these lists in WebMarshal URL Categories.
The Filtering Lists pane displays information about the lists currently configured in WebMarshal. You can enable or disable an existing list. You can add or delete lists. WebMarshal currently supports the following lists:
•FileFilter: A simple implementation that reads category lists from text files. For more details about FileFilter please see “FileFilter”.
•URLCensor: A real-time facility that categorizes IP addresses through DNS Blacklist lookup. For more details about URLCensor please see “URLCensor”.
•Trustwave Web Filter Database: A URL list provided by Trustwave and licensed separately. The list consists of 116 categories. For more information on the Trustwave Web Filter Database including trial license information, please see “Trustwave Web Filter Database”
7.3.1 Reviewing Filtering List Status
You can check the available categories, enabled or disabled status, and update status for any configured list, and update the list or license if required.
To check the list:
1.In the left pane tree, expand URL Filtering Lists.
2.Select a list. The top right pane shows the status of the list on each server. The bottom right pane shows the name and description of each category available through the list.
3.To view general details of a list, or to initiate an update for all servers, right-click a list name in the left pane. Click Update All Servers to force an immediate check for Filtering List updates (where internet updates are provided).
|
Note: Updating can cause disruption for users browsing. This action should be performed at a time when it will have minimum effect. |
4.To view details of list and license status on each server, double-click a server name in the right pane. The Node Update Status tab shows the update status and results for the server.
You can add one or more filtering lists to the WebMarshal configuration. For additional details, see Help.
To add a filtering list:
1.In the left pane tree, expand URL Filtering Lists.
2.In the right pane, click Add URL Filtering List to start the Add URL Filtering List wizard.
3.Select a single list to add. Click Next.
4.For the Trustwave Web Filter Database, to allow WebMarshal to validate the license (one time requirement), select an Internet connection method that is valid from the WebMarshal Array Manager server, and then click Next.
5.Click Finish to validate the license (if required) and add the list.
6.To add another list, repeat the above steps.
7.Commit configuration changes to propagate the new list to the WebMarshal servers.
After adding a filtering list, you can use the categories from that list by inserting them into WebMarshal URL Categories. See “Adding Categories to a URL Category”.
|
Note: WebMarshal will use the categories for filtering as soon as the list is available on processing servers. For the Trustwave Web Filter Database, the initial population of categories can take half an hour or longer, depending on Web connection speed. |
7.3.3 Deleting a Filtering List
You can delete a filtering list from the WebMarshal configuration. Deleting a list removes any categories imported from the list from the WebMarshal URL Categories. Deleting a list does not remove database log records of categorized sites.
To delete a filtering list:
1.In the left pane tree, expand URL Filtering Lists.
2.Right-click the list you want to delete, and select Delete.
3.Commit configuration changes.
7.3.4 Enabling or Disabling a Filtering List
You can enable or disable use of a Filtering List. When a list is disabled, the list and imported categories will display in the Console, but the list will not be updated and it will not be used in rules.
To enable or disable a filtering list:
1.In the left pane tree, expand URL Filtering Lists.
2.Right-click the list you want to change, and select Enable or Disable.
3.Commit configuration changes.
