Discussion

To prevent the compromise of authentication information, such as passwords during the authentication process, the feedback from the operating system must not provide any information allowing an unauthorized user to compromise the authentication mechanism. Obfuscation of user-provided information that is typed into the system is a method used when addressing this risk. Displaying asterisks when a user types in a password is an example of obscuring feedback of authentication information.

Fix Text

Define a clear string used to obliterate the logon to ASCII CRT devices.

STRING(A12FA11C1A270C0D)

Example:
SET C(GSO)
INSERT TSOCRT STRING(A12FA11C1A270C0D)
