iFIX 4.0 and greater gives you the ability to create site-specific passwords to prevent unauthorized iFIX installations from communicating.
You can change the default password used to validate and authenticate network transmissions. This allows you to set up multiple iFIX networks with different passwords, thus isolating iFIX networks from each other. As a result, non-configured or default installations cannot be used to initiate communications in an iFIX network.
Only by having two or more iFIX 4.0 or greater machines properly configured will the authentication be used.
Site-specific authentication is achieved by enabling the Enforce Trusted Computing option and setting the password in the Network Password field in the Network Configuration dialog box on the System Configuration Utility (SCU), as shown in the figure below.
The password is masked and case sensitive, and is encrypted in the SCU file. This is the physical layer of security for the network password.
The default password, displayed in the Network Password field, is provided for legacy iFIX installations. For more information, refer to the Connection Authentication section.
If the SCU file is copied to a different machine, a pop-up message appears warning you that it is invalid when the SCU file is open and/or when iFIX starts. You will be required to enter the network password in the SCU if you need to establish a network connection with 'Enforce Trusted Computing' enabled.
