This is a slightly off-topic post picked up from the Adventures in system land blog; it talks about mainframe systems, but there is a good quote I’d like to highlight:

It is that you can show who did what, when, and how. Auditing is much more important than security.
In a banking environment one can see why this is highlighted, but what about general purpose personal computers? The Trusted Platform Module does support audit trail creation, but how does this enhance security? This is something that I should study further.
