Fix Recommendation

Ensure all switch profiles are special WebSphere MQ profiles that are used to turn on/off security checking for a type of resource. Due to the security exposure this creates, no profiles with the first two qualifiers of ssid.NO will be defined to the MQADMIN or MXADMIN class, with one exception. Due to the fact that (1) all sensitive WebSphere MQ commands are restricted to queue managers, channel initiators, and designated systems personnel, and (2) no command resource checking is performed on DISPLAY commands, at the discretion of the ISSO, a ssid.NO.CMD.RESC.CHECKS switch profile may be defined to the MQADMIN or MXADMIN class.

Identify if any switch profiles exist using the sample search command:

SR CLASS(MQADMIN) NOMASK FILTER(*.NO.**)

Use the "RDEL MQADMIN <SwitchProfileName>" to remove the profile and follow up with a "SETR RACL(MQADMIN) REF".

An additional refresh to an active WebSphere MQ queue manager may be required. A sample is shown below using the value QMD1 as the queue manager name.

From the Console:

>QMD1 REFRESH SECURITY(*)

Check Contents

Refer to the following report produced by the z/OS Data Collection:

- MQSRPT(ssid)

Automated Analysis requires Additional Analysis.
Refer to the following report produced by the z/OS Data Collection:

- PDI(ZWMQ0051)

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

Review the Security switches identified in response to the DISPLAY SECURITY command in each ssid report(s). If all of the following switches specify ON, this is not a finding.

SUBSYSTEM
CONNECTION
COMMAND
CONTEXT
ALTERNATE USER
PROCESS
NAMELIST
QUEUE
TOPIC
COMMAND RESOURCES

If SUBSYSTEM specifies OFF, this is a finding with a severity of Category I.

If any of the other above switches specify OFF (other than the exception mentioned below), this is a finding and downgrade the severity to a Category II.

If COMMAND RESOURCE Security switch specifies OFF, this is not a finding.

Note: At the discretion of the ISSO, COMMAND RESOURCE Security switch may specify OFF by defining ssid.NO.CMD.RESC.CHECKS in the MQADMIN (or MXADMIN if SCYCASE is set to MIXED) resource class.
