Fix Recommendation

Review the following connection resources defined to the MQCONN resource class:

Resource Authorized Users
ssid.BATCH TSO and batch job userids
ssid.CICS CICS region userids
ssid.IMS IMS region userids
ssid.CHIN Channel initiator userids

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

c) For all connection resources defined to the MQCONN resource class, ensure the following items are in effect:

NOTE: If you do not have a resource profile defined for a particular security check, and a user issues a request that would involve making that check, MQSeries/WebSphere MQ denies access.

1) Resource profiles are defined with a UACC(NONE).
2) Access authorization to these connections restricts access to the appropriate users as indicated in (b).
3) All access FAILUREs are logged.

A set of sample commands are provided below to implement the minimum profiles necessary for proper security. Note that the IMS and/or CICS profiles can be omitted if those products do not run on the target system.

Note that an additional WebSphere MQ Refresh may be required for active Qmanagers. This is done from the CONSOLE:

The example is for a Que Manager Named QMD1

3) All access FAILUREs are logged.

d) If all of the items in (c) are true, there is NO FINDING.

e) If any item in (c) is untrue, this is a FINDING.
