RFC Security, Science-Fiction and Theatre
RETURN MODIFICATIONS TO SAP STANDARD
When I began my career administering SAP ERP on Oracle in the early 1990s, running a database required far more knowledge. An Oracle administration expert with a decade of experience understood perhaps only about 5% of what the database required.
Information technology plays an even more important role in the age of digitalisation. Innovation without IT is unimaginable. But it is not just technology itself, but also how it is delivered that matters. The SAP basis sees itself as a partner and contact for new SAP technologies. Further details on the recommendation can be found in the Master's thesis in chapters 7.5 and 9.3.
Schedule user matching as a background job
This makes the technical user the dialogue user and a login in the SAP system is unrestricted. So Johannes logs in with the known password of the RFC user in the production system. Thanks to very extensive permissions, it now has access to all sorts of critical tables, transactions, and programmes in production. With the identity of the RFC user Johannes starts with the technical compromise of the production system... RFC Security: All invented - or everyday threat? Whether a simple trim, altered biometric properties or an encapsulated technical user in the SAP system: the basis of the compromise is the same. A person uses a different identity to gain access and permissions to protected areas. Moreover, the evil in all three stories could have been prevented by pro-activity. When was the last time you thought about the security of your RFC interfaces? Can you say with certainty that all your technical RFC users only have the permissions they actually need? And do you know who exactly knows the passwords of these users? Can you 100% rule out that not now in this moment an SAP user with a false identity infiltrates your production systems? Change now: It's about pro activity! But before you start now and start looking for the "identity converter" (which I really do not recommend!), I suggest that you take root of evil and proactively strengthen your RFC security. So if you want to find out more, I have the following 3 tips for you: 1) Our e-book about SAP RFC interfaces 2) Clean up our free webinar about RFC interfaces 3) Blog post about our approach to optimising RFC interfaces As always, I look forward to your feedback and comments directly below these lines!
SAP Basis refers to the administration of SAP system that includes activities like installation and configuration, load balancing, and performance of SAP applications running on Java stack and SAP ABAP. This includes the maintenance of different services related to database, operating system, application and web servers in SAP system landscape and stopping and starting the system. Here you can find some useful information about SAP Basis: www.sap-corner.de.
So much information... how can you keep it so that you can find it again when you need it? That's what Scribble Papers is great for.
SAP Basis is the foundation of every SAP system. On this page you can find out what is behind the term and what SAP Basis is responsible for in detail.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".
In a change of department or a new activity, permissions are automatically adjusted.
