Fix Recommendation

The ISSO will ensure that use of alternate userids is restricted to authorized personnel.

For all alternate user resources (i.e., ssid.ALTERNATE.USER.alternatelogonid) defined to TYPE(MQA) (MQADMIN resource class or MXADMIN if SCYCASE is set to MIXED), 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).

Example:

$KEY(ssid) TYPE(MQA)
ALTERNATE.USER.- UID(CICS support) SERVICE(READ,UPDATE) LOG
ALTERNATE.USER.- UID(*) PREVENT

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

- SENSITVE.RPT(MQADMIN).
- SENSITVE.RPT(MXADMIN).
- ACF2CMDS.RPT(RESOURCE) - Alternate report.

For all alternate user resources (i.e., ssid.ALTERNATE.USER.alternatelogonid) defined to TYPE(MQA) or TYPE(MXA) (i.e., MQADMIN or MXADMIN resource class, if SCYCASE is set to MIXED), verify 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. If this guidance is true, this is not a finding.

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