Re: disable all Q* ibm supplied profiles and chaning default passwords

I agree with Rob. We've had QSECOFR disabled a few times and all manner
of OS functions began failing. YMMV

I respectfully disagree - QSECOFR is disabled on all of my partitions (my
user profile is QSECOFR equivalent) and is only enabled when some lame POS
(piece of software) absolutely must have QSECOFR to install - which is
almost never. Additionally, I have been in many security sessions where it
was specifically recommended to disable QSECOFR.

Additionally, QPGMR,QSRV, and QSYSOPR are disabled on all partitions. All
other 'Q' profiles are left as shipped unless I have stumbled across some
IBM document that specifically states that they can be disabled.

There are a few Q profiles that simply won't allow you to change them
period and a few that I don't think I would want to disable (such as QTCP,
QLPINSTALL, and QSYS to name a few).

Thanks,

Do not disable QSECOFR. So much will fail.
You know how you can adopt programs to run under QSECOFR?
You know how you can use profile swapping to run under QSECOFR?
Well, IBM has some internal methods which are not known to us Muggles
which also run under QSECOFR. I found this out by tapping the audit
journals in an effort to find when high profile users are being used.
It happens so often it will blow your mind.
