Fix Recommendation

For all alternate user resources (i.e., ssid.ALTERNATE.USER.alternateuserid) defined to MQADMIN or MXADMIN resource class, 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).

The following is a sample of the commands required to allow payroll server (PAYSRV1) to specify alternate userids starting with the characters PS on queue manager (QM1):

TSS ADD(USER1) FAC(QM1MSTR)
TSS PER(USER1) MQADMIN(QM1.ALTERNATE.USER.PS)
ACC(UPDATE) ACTION(AUDIT)

For all alternate user resources (i.e., ssid.ALTERNATE.USER.alternatelogonid) defined to MQADMIN resource class (or MXADMIN resource class, 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. If this guidance is true, this is not a finding.

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