IBM z/OS MCS consoles access authorization(s) for CONSOLE resource(s) must be properly protected.
An XCCDF Rule
Description
<VulnDiscussion>MCS consoles can be used to issue operator commands. Failure to properly control access to MCS consoles could result in unauthorized personnel issuing sensitive operator commands. This exposure may threaten the integrity and availability of the operating system environment, and compromise the confidentiality of customer data. Preventing non-privileged users from executing privileged functions mitigates the risk that unauthorized individuals or processes may gain unnecessary access to information or privileges. Privileged functions include, for example, establishing accounts, performing system integrity checks, or administering cryptographic key management activities. Non-privileged users are individuals that do not possess appropriate authorizations. Circumventing intrusion detection and prevention mechanisms or malicious code protection mechanisms are examples of privileged functions that require protection from non-privileged users.

Remediation - Manual Procedure
Define all MCS consoles to the CONSOLE resource class and configure READ access to be limited to operators and system programmers.
Configure the MCS console resources defined to z/OS and the ESM to conform to those outlined below.
Each console defined in the CONSOLxx parmlib member is defined to RACF with a corresponding profile in the CONSOLE resource class. See the IBM zOS OPERATIONS AND PLANNING guide for further information.
