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.

a) Refer to the following report produced by the ACF2 Data Collection: - SENSITVE.RPT(MQADMIN) - ACF2CMDS.RPT(RESOURCE) – Alternate report b) For all alternate user resources (i.e., ssid.ALTERNATE.USER.alternatelogonid) defined to TYPE(MQA) (i.e., MQADMIN resource class), ensure access authorization restricts access to users requiring the ability to use the alternate userid. This is difficult to determine. However, an item for concern may be a profile with * READ specified in the access list. NOTE: ssid is the queue manager name (a.k.a., subsystem identifier). c) If (b) is true, there is NO FINDING. d) If (b) is untrue, this is a FINDING.
