 My major concern is auditing. While I trust that the implementation
 will take care of auditing in the ESM, it makes it much harder to see
 who has been messing with it.  Normally when a user tells his server
 suddenly failed you could scan the PROP logging and see which of the
 developers reconnected, and tell him to hit his peer over the head
 with it. But when neither of the virtual machines has its console
 spooled, you would not be able to tell what happened.

Command auditing is already provided by ESMs.  Nothing would change in 
that respect. 

 Oh, and how about RACF restrictions that apply to the LOGON (like
 terminal or time) ? How would that apply to the proposed commands?

No change.  The conditional access list for LOGON is not applied to other 
CP commands.  Further, it only applies at the point the user is logged on. 
 Once logged on, those restrictions are never imposed again.  No double 
jeopardy.

 If you really think this is useful, then use different profiles in the
 surrogate class (e.g. MAGICBY.target) so that an installation can
 decide which end users are able to use this.

That is what I originally envisioned and remains my fall-back position.

Thank you, everyone, for your considered comments.  I've gotten what I 
needed.

I should point out, however, that the class G FOR command requires you to 
be the SECUSER of the target.  With an ESM, if you are not the SECUSER, 
then LOGON BY authority is sufficient.

And I recall at one point the driver would tolerate any order, but
expected an even virtual address to be an even real address as well...

It's different type of auditing, with different audience. When I would
be paged in the middle of the night, I could search the operator
console for smoking guns. Being able to see who was tampering with the
thing the night before is enough to divert the call.
Many installations will not allow the average support person to run
SMF reports. And if they allow, it's not as much fun that I would like
you to wake me up for it...

Re: How to insert zvse4 installation tapes without barcode label on 3953/3584 library

2007-08-26 Thread [EMAIL PROTECTED]
Of course, the problem is independent of the operating system you want 
to install. The problem is not the standard label written on the tape 
but barcode label on the cartridge. The library does not check the 
written magnetic SL on the tape when importing it. In my case the 
customer has opened in parallel a pmr on the hardware and they gave the 
same explanation that I gave here on the list. The local IBM service guy 
will give the customer some barcode labels which he can stick on the 
cartridge and everything is fine. The easiest way for IBM to solve the 
problem is to put a barcode label  on each cartridge per default like 
ZVM531, 532 and so on or VSE411, 412 , ZOS191, 192, ... At the worst 
case the customer has such a label in his library, - which I don't 
really believe -, and he has to eject these cartridges, import the 
installation cartridges, copy these cartridges to own ones and reimport 
the original ZVM-, VSE- or ZOS- labeled cartridges. The other 
possibility is to give the library the functionality in the microcode to 
import unlabeled cartridges like it was on the 3494. If IBM doesn't give 
the customer one of these possibilities they can soon begin to stop 
creating cartridges as the 3584/3953 libraries will more and more 
replace the 3494 installations and deliver the software only on CD/DVD. 
As this is currently possible on z/VM and z/VSE it is not on the 
self-defined Mercedes of IBM, z/OS. This has surely something to do 
with the amount of data (at least 6 3390-3) and the lack of a kind of 
virtual tape server as in VSE to read directly from AWS simulated tape 
files.

Thank you to all who have responded. Let's hope, that IBM will either
put labels on future installation cartridges or make it possible to
mount unlabeled cartridges on the 3584 library.



What did the z/VSE Support Center say when you asked them?  I can tell you 
that z/VM does not ship SL tapes and so would not have a volser 
machine-readable external label.


According to the brochure for 3592s, the barcode label is required to load 
the tape in an IBM tape library.

Re: Ops privs

2007-08-26 Thread David Boyes
 Bundle RACF??? That might be a blow to the users of VM:Secure and
other
 ESMs.

Is it? Let's think about that: 

1) The major difference between RACF and the alternatives is that all of
the alternatives are easier to use, administer, operate and understand.
How does bundling RACF change that? 

2) Installing RACF or any of the alternatives involves a CP mod.
Removing RACF and installing an alternative isn't any more complicated
than removing the dummy RPI modules and replacing them with your chosen
substitute.

3) How many of the alternatives are getting more than life-support style
maintenance? CA doesn't promote VM:Secure any longer (not the
strategic solution), and ACF2/VM isn't exactly healthy either.  What
else is left?

4) RACF (with all it's grotesque hideousness) shares (or can share)
development costs with the z/OS version. Is it really worth asking IBM
to duplicate that effort in CP just to get ESM functionality, or invent
something else (implying all the development, testing, documentation and
support) when it's a question of figuring out how to license something
that already exists?

5) There are a fair number of places where CP and CMS command logging
and authorization is inconsistent or REALLY hard to understand (take SFS
auth for starters), and a lot of effort is performed to kludge around
the absence of an ESM. Even a horrible ESM like RACF is better than no
ESM. Why can't we kick up the base level a notch, if there's a fairly
easy way to do it? 

It just strikes me as a waste of effort to keep kludging around with the
base CP security model and inventing half a dozen different ways to do
command authorization and logging if we can do it by asking IBM to step
up the base model with something that doesn't require them to do (and
maintain) new development.

Re: Ops privs

  Then you can start on command operand authorization...8-)
 Oh no... you gave Chucky a new idea. We'll blame you for all that
 comes out of this.

Oh, we've been chatting about this one for a long, long time...he's long
since corrupted. The problem is finding a way to juggle priorities to
let him do it...8-)

 Most CP commands right now only allow the ESM to audit, not to control
 access. If the ESM gets granular access control, we need a a lot of
 new error messages to reflect that.

Or just one: 

HCPE Command option not permitted by security profile. RC=1234

Exactly what isn't permitted isn't the end user's business (to prevent
gaming the system and determining what options are permitted by trial
and error), but should be recorded in the ESM log. 

 An easy API for
 RACROUTE might be nice to avoid yet-another-list of powerful users
 (especially since some weasels want that all disks with lists of
 powerful users are protected against reading).

Takes us back to either a universal *RPI service provider built into CP
that we can connect to with pipes and do our own ESM, or supplying a
default ESM that's more granular than the classic CP model, doesn't it?
