Secret Signature
The Secret Signature is a Cyber Security feature facilitating a user managed layer of protection on the Session Cookie for the HMI
Interface. The G500 creates its own session cookie based on hashing a configurable sentence, called "Secret Signature".
To ensure session cookie uniqueness users should change the Secret Signature.
To change the Secret Signature:
1.
Launch DS Agile MCP Studio and connect to G500 using a nominated administrator user.
2.
With the Offline or Online Editor, navigate to Systemwide > Access Manager tab.
3.
Change the Secret Signature from the default to user defined and select "Save" button.
4.
Apply "Sync To" in the case of Offline Editor to apply these changes to G500. In the case of Online Editor, these changes
will be reflected automatically when User applies "Save" button.
5.
Re-Login from the G500 Runtime HMI or G500 Command Line to check the updated Secret Signature.
Note: The default secret signature should be replaced with a secure signature chosen by your security administrator. This needs
to be done after successful creation of nominated administrator level user.
