To help protect your system from unauthorized use, we recommend that each ClearSCADA server is configured to accept only secure connections from ViewX clients (see Define Whether the Server Only Accepts Secure Connections in the ClearSCADA Guide to Security). With such configuration, each ViewX client has to be set to communicate with the server using a secure connection. This setting is configured on a per-client basis, using the Client Configuration window.
With new installations, the ClearSCADA server is configured to accept only secure connections from ViewX clients by default.
If the servers on your system accept both secure and insecure connections from ViewX clients, you can specify, on a per client basis, whether each ViewX client uses a secure connection to communicate with the server.
To specify whether a ViewX client uses a secure connection:
- Display the Client Configuration Window for the connection that you want to add or edit.
- Either:
- Select the Secure Connection check box (the recommended setting). The ViewX client will use a secure connection for communications with the ClearSCADA server.
Or:
- Clear the Secure Connection check box. The ViewX client will use an insecure connection to communicate with the ClearSCADA server. We do not recommend this option as the use of insecure connections could compromise the security of your system.
Be aware that if a server is configured to only accept secure connections from ViewX clients, you will be unable to connect to that server using a ViewX client on which the Secure Connection check box is clear.
WARNINGSECURITY RISK
Clearing the Secure Connection check box could compromise the security of your system. Unauthorized users could gain access to your systemFailure to follow these instructions can result in death, serious injury, or equipment damage.
- Either select the OK button to close the Client Configuration window, or proceed to configure other settings in the window as required (see Create a New ViewX Client - System Connection).
