Blocking sites temporarily with service settings

Blocking sites temporarily with service settings

Use service properties to automatically and temporarily block sites when incoming traffic attempts to use a denied service. You can use this feature to individually log, block, and monitor sites that attempt access to restricted ports on your network.

Configuring a service to temporarily block sites

Configure the service to automatically block sites that attempt to connect using a denied service. From Policy Manager:

1Double-click the service icon in the Services Arena.

The Properties dialog box appears.

2Use the Incoming Service Connections Are drop list to select Enabled and Denied.

3Enable the Auto-Block Sites that Attempt to Connect Via checkbox.

To change the auto-block duration, see “Changing the auto-block duration” on page 44.

Viewing the Blocked Sites list

Use Firebox Monitors to view sites that are automatically blocked according to a service’s property configuration. From the Control Center:

1On the QuickGuide, click the Firebox Monitors icon.

2Click the Blocked Site List tab. (You might need to use the arrows to access this

tab.)

The Blocked Sites list appears.
