Title

WebSphere MQ command resources defined to MQCMDS resource class are not protected in accordance with security requirements. (Cat II impact)

Discussion

WebSphere MQ resources allow for the control of commands. Failure to properly protect WebSphere MQ Command resources may result in unauthorized access. This exposure could compromise the availability, integrity, and confidentiality of system services, applications, and customer data.

Check Content

a) Refer to the following reports produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(MQCMDS) b) For all command resources (i.e., ssid.command) defined to the MQCMDS resource class, ensure the following items are in effect: NOTE: ssid is the queue manager name (a.k.a., subsystem identifier). 1) Resource profiles are defined with a UACC(NONE). 2) Access authorization restricts access to the appropriate personnel as designated in the Websphere MQ COMMAND SECURITY CONTROLS Table in the z/OS STIG Addendum. 3) All command access is logged as designated in the Websphere MQ COMMAND SECURITY CONTROLS Table in the z/OS STIG Addendum. c) If all of the items in (b) are true, there is NO FINDING. d) If any item in (b) is untrue, this is a FINDING.
