Mainframes on the Net?

[Don Kendrick <don () netspys com>]

OK...maybe a little of topic but this is the group that would know :)

There is quite a push from our IBM friends to use the S/390 box for a 
web server using Websphere or Apache running under Linux (either as a 
VM or in it's own LPAR).

Needless to say, I considered this to be a joke....putting the crown 
jewels on the net? Where's the multi-tiered architecture? Where's the 
"defense in depth?" Sure the S/390 has "never been hacked" (their 
words) but who has ever put it in a position to be hacked?

They tell me that I don't understand LPARs. They're separate machines. 
You can still do your multi-tiered. It's just all on the same box.  My 
fear, they are separate because of software, written by humans. If that 
is breeched, it's game, set and match.

If they were separate boxes, they would have to communicate via some 
interface that I can monitor. This isn't true all on one box.

Anyone have any experience with this fight? Am I out of line?

Don
