Security fix

Fixed an Information and Stack Trace disclosure for GET requests with malformed parameters to an API endpoint.

Best Practices

Use Kerberos realm name that follow the standard naming structure. For example, DNS domain name in uppercase.
User sessions - The following best practices helps avoid performance degradations gradually over a period of time due to increased login sessions as well as security vulnerabilities such as unauthorized access to the active HMC sessions.

It is a best practice to logoff from HMC UI and then close the browser tab instead of directly closing the tab
Set Idle session timeout for all the users and not leave the timeout as '0' which leaves it as no timeout.
