Description
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.

Who does this work

6 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Details

Check Text (C-223510r958470_chk)

From the ISPF Command Shell enter: ACF SET CONTROL(GSO) <enter> LIST TSOCRT If the GSO TSOCRT record values conform to the following requirements, this is not a finding. STRING(A12FA11C1A270C0D)

Fix Text (F-25171r500664_fix)

Define a clear string used to obliterate the logon to ASCII CRT devices. STRING(A12FA11C1A270C0D) Example: SET C(GSO) INSERT TSOCRT STRING(A12FA11C1A270C0D) F ACF2,REFRESH(TSOCRT)
