SAP Pen-testing - complexity - first ideas

Since my previous SAP post I've read a bit more and talked with colleagues 
and played with some SAP transactions.
I will write a more structured post in the coming days, but here is some 
nice info:

A very good article on SAP password attacks:

A concise introduction into SAP Security, in German, but there may be an 
English version too on te same site:

Two alerts that sound ominous, but I've not found more details yet:

A list of potential Web insecurities in SAP, just all the common web 

Attempt to reverse engineer SAP protocol:

My feeling at the moment (but that may change):

- risks in underlying operating system (Unix/Windows) and database system 
(Oracle/SQLServer) are relatively easy to handle if you don't misconfigure 
anything, there are just a handful of tricky accounts and these need to be 
secured well

- as long as SAP is on an internal network without web-portal 
functionality risks seem to be acceptable, encrytion of network data can 
be strenghtened, but most organizations simply don't bother

- biggest risks in SAP web presence might be detectable by running a good 
web scanner like Appscan / Webinspect

- the biggest security risk comes from SAP itself, where there exist 
tharnsactions to manipulate the database itself and the underlying 
operating system, and there are so many transactions and so complex access 
rights to transactions, that a SAP-admin or often even a SAP-user (I'm 
told) can run dangerous code

So to make progress with SAP pentest you need to play around with SAP 
itself and not with the underlying network-, database- and OS- building 
blocks. (but this idea may change still)

I'm very curious about your opinions and any more interesting links. After 
all I'm still a SAP beginner ...

Sincerely yours, Petr Kazil
