Does anybody know good links and resources on general security issues for SAP R3? I am basically looking for the whole picture from authorization, authentication, confidentiality, integrity, auditing, network layout, non-repudiation a.s.o. I have not yet found good resources with a holistic approach. I am looking for a kind of a security architecture guide or discussion paper on new to be implemented systems. I would be very happy about some hints. Thanks in advance.
