WebSphere MQ Namelist resources must be protected in accordance with security requirements.

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.

Refer to the following report produced by the ACF2 Data Collection:

- SENSITVE.RPT(MQNLIST). - SENSITVE.RPT(MXNLIST). - ACF2CMDS.RPT(RESOURCE) - Alternate report.

For all namelist resources (i.e., ssid.namelist) defined to TYPE(MQN) or TYPE(MXN) (i.e., MQNLIST or MXNLIST resource class, if SCYCASE is set to MIXED), verify access authorization restricts access to users requiring the ability to make namelist inquiries. This is difficult to determine. However, an item for concern may be a profile with * READ specified in the access list. If this guidance is true, this is not a finding.

Note: ssid is the queue manager name (a.k.a., subsystem identifier).

The ISSO will ensure that all WebSphere MQ namelist resources are restricted to authorized users.

For all namelist resources (i.e., ssid.namelist) defined to TYPE(MQN) (i.e., MQNLIST resource class or MXNLIST resource class if SCYCASE is set to MIXED), ensure access authorization restricts access to users requiring the ability to make namelist inquiries. This is difficult to determine. However, an item for concern may be a profile with * READ specified in the access list.
