The core component of SAP Basis is the application layer. It contains one or more application servers and a message server.
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 usually takes care of the administration of the SAP system. The most important SAP Basis transactions are listed in this article.
Presentation layer: The presentation layer is the interface to the users. With the help of SAP GUI, the data is graphically prepared here and made available to the user on the screen. Furthermore, the data newly collected here is passed on to the application programs of the application layer.
"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.
It enables the use of external programs via interfaces or the call of ABAP programs and serves as a technical component of the application server, which manages the communication of all RFC-based functions.
Some useful tips about SAP basis can be found on www.sap-corner.de.
It is important to use either"'SHOW" or "UPDATE" because a combination will cause an error when calling the parameter transaction.
