DRIVE TASK AUTOMATION
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!
Reduce resources: depending on the agreement of the contract, you can ask for the service resources only when needed. This will save you some costs.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
Restricting the user name in the SAP system
For example, many customer ABAP programs work by uploading or downloading data. There are potentially large security gaps here that allow access to server data. In addition, the widespread direct invocation of operating system commands that are not covered by a self-programmed authorization check is a major problem. Even though classic SQL injection, i.e., the entry of extended SQL commands, is a potential security vulnerability, it occurs rather rarely in SAP systems. More widespread is the unintentional dynamization of SQL calls because input parameters are not sufficiently checked. The need to check all in-house developments internally for such security vulnerabilities before they are delivered in SAP's own code has led to the development of the SAP Code Vulnerability Analyzer tool.
Database layer: The database layer contains a database server on which all the data of the SAP ERP system is managed. This includes the database management system (DBMS for short) and the actual dataset. The dataset includes user data and data tables as well as applications and system control tables.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".
EPILOGUE In this step the insertion is completed.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
After my research, I came across a simple way to have your SQL statements resolved transaction-based by an editor.
