Websphere MQ switch profiles must be properly defined to the appropriate class.

Severity	Group ID	Group Title	Version	Rule ID	Date	STIG Version

Description
WebSphere MQ resources allow for the control of administrator functions, connections, commands, queues, processes, and namelists. Some resources provide the ability to disable or bypass security checking. Failure to properly protect WebSphere MQ resources may result in unauthorized access. This exposure could compromise the availability, integrity, and confidentiality of system services, applications, and customer data.

ℹ️ Check
a) Refer to the following report produced by the OS/390 & z/OS Data Collection: - MQSRPT(ssid) NOTE: ssid is the queue manager name (a.k.a., subsystem identifier). Automated Analysis requires Additional Analysis. Automated Analysis Refer to the following report produced by the OS/390 & z/OS Data Collection: - PDI(ZWMQ0051) b) Review the Security switches identified in response to the DISPLAY SECURITY command in each ssid report(s). If all of the following switches specify ON, there is no finding. SUBSYSTEM CONNECTION COMMAND CONTEXT ALTERNATE USER PROCESS NAMELIST QUEUE COMMAND RESOURCES c) If SUBSYSTEM specifies OFF, this is a finding with a severity of Category I. d) If any of the other above switches specify OFF (other than the exception mentioned below), this is a finding and downgrades the severity to a Category II. e) If COMMAND RESOURCE Security switch specifies OFF, there is no finding. NOTE: At the discretion of the ISSO, COMMAND RESOURCE Security switch may specify OFF by defining ssid.NO.CMD.RESC.CHECKS in the TYPE(MQA).

✔️ Fix
Ensure that all Switch Profiles do not have the resource ssid.NO defined to the MQADMIN (or MXADMIN if SCYCASE is set to MIXED) resource class with the exception of ssid.NO.CMD.RESC.CHECKS. ssid is the queue manager name (a.k.a., subsystem identifier). Ensure that all of the following switches specify ON.
