8.4 Blocking network connections
You can manually block network connections for cases in which someone brings in a computer from outside or if security measures are not fully implemented on a computer.
You can only block network connections of computers in network segments for which the network monitor is enabled.
To block a network connection:
-
Display the Device module.
-
In the menu area, select Device Inventory and then Network List. In the Network List view, select the network segment containing the computer that you want to block.
-
In the information area, select the computer that you want to block from the network. Select Action and then Deny Network Access.
-
In the displayed dialog box, select Continue Operation, and then click OK.
The selected computer is blocked from the network. The Connection to Network setting of the network control list changes to Deny.
If you select Send User Notification, you can send a message to the user of the selected computer. If you select more than one computer, you can send the same message to the users of those computers.
If you select Add Notes for a selected computer, you can keep track of information on when and why its network connection is blocked. Information entered here will be added to the Notes tab.

If a network connection is manually blocked, the network connection is automatically disallowed.
