In order to escape the checks carried out by the iris scanners and ultimately his own arrest, a doctor illegally reuses his eyes and acts under a new identity. With the help of the new eyes he finally succeeds in entering the secured area of the "Precogs" and he can begin his investigation. Through this "biohacking" he not only deceives the biometric security systems - he compromises the highest police control system. All stories!? "Great stories!" think now. But: No one will ever fall for a simple trim. And anyway: Biometric security systems and eye transplantation? It's not for nothing a science fiction movie! What does this have to do with RFC security? All right, I can understand your doubts. But how do you like the following story, for example? RFC Security and the Art of Identity Change Germany, everywhere, 2017: Johannes Voigt has been a medium-sized company employee for several years. He is considered a reliable and conscientious developer from the IT department. In fact, he is increasingly unfairly treated. He decides that he no longer wants to carry his frustration with him.
SAP Authorization Concept
He has already gathered a lot of helpful information from the day-to-day business in his department: Johannes knows the RFC interfaces and the corresponding technical RFC users from his work with the applications. He also quickly got the password for various RFC users via the radio ("As long as passwords are only communicated by phone and never exchanged in writing, we are clean!"). And that the RFC users are generously entitled even in productive systems is no longer a secret ("Better to have more permissions than too little; the RFC connections have to run, otherwise there is trouble from the specialist areas!"). Since Johannes has access to the SE37 as a developer, it is not a problem to get the necessary access using the function block BAPI_USER_CHANGE - disguised as RFC User. In short, it changes the user type of a technical RFC user in a production system from to by calling the function block.
In the authorization environment, in addition to assigning authorizations to SAP users, there are a number of important SAP Basis settings that you should check regularly to ensure that your SAP system is fully protected, both internally and externally. For example, particularly in the context of an audit, it is important to ensure that changes to the SAP system always remain traceable. In this blog, I would like to show you how you can best implement this and what to look out for.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
If you want to skip the entry dialogue when invoking the parameter transaction, and there is no way to open tables other than the one you want, make sure to select "Skip Entry Image".
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.
