Fix Recommendation

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.

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

Example:

$KEY(QZN1) TYPE(MQN)
SYSTEM.DEFAULT.NAMELIST UID(MQAdministrators) SERVICE(READ) LOG
SYSTEM.DEFAULT.NAMELIST UID(*) PREVENT

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).
