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. In a multi-server configuration, you can block network connections only for the computers immediately under the local server.

You can only block network connections of computers in network segments for which the network monitor is enabled.

To block a network connection:

  1. Display the Inventory module.

  2. 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.

  3. In the information area, select the computer that you want to block from the network. Select Action and then Deny Network Access.

  4. 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. Note that you cannot send messages to agents for UNIX or Mac.

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.

Important

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

Important

Network connections are not blocked from computers in network segments for which the network monitor is disabled, even if Connection to Network is Deny.

Tip

You can allow a network connection by selecting Computer Security Status and then Network List in the Security module, and then using the Network List view. You can also allow a network connection by selecting Network Access Control and then Network Filter Settings in the Settings module, and then using the Network Filter Settings view.

Tip

When a network connection is blocked, a message might be displayed to indicate that an IP address conflict has occurred for the device.
