Read the old state and match with the new data
Protect your system from unauthorised calls to RFC function blocks from the S_RFC authorization object by obtaining the necessary permissions using the statistical usage data. In many organisations, the primary focus in the permission environment is on protecting dialogue access. For each required transaction, you decide in detail which groups of people are allowed access. It is often overlooked that the critical S_RFC privilege object requires an analogue permission assignment. If the RFC (Remote Function Call) external access permissions are unneatly defined and assigned to the users, the S_TCODE authorization object quickly bypasses the primary protection for bootable applications.
Authorizations are the main controlling instrument for mapping risk management and compliance. They are used to control all processes in the systems. For the most part, separation of functions is implemented exclusively with authorizations. Therefore, not only the one-time setup of authorizations is relevant, but also the continuous monitoring and control of the authorization assignment. Various tools are available on the market for this purpose. A re-certification process that involves the departments and optimizes the revalidation of authorizations is helpful.
Check for permissions on the old user group when assigning a new user group to a user
On the topic of SAP authorizations and SAP S/4HANA, I can recommend the SAP online course by Tobias Harmes as blended learning from Espresso Tutorials for SAP administrators, ABAP developers and people who are currently or will be dealing with SAP authorizations. The online course covers the following topics: - Introduction to the course - Why are SAP authorizations actually important? - How do SAP authorizations work technically? - Developing and maintaining roles - SAP Fiori authorizations/tile authorizations in S/4HANA - Developing authorization checks.
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.
Access options and authorizations are defined and controlled in the SAP authorization concept. How secure business data is in SAP depends largely on the assignment of authorizations and access options for a company's users.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.
The result list shows all the authorised tables, their permissions, and their permission values.
For example, you can also include the DISABLE_PASSWORD_LOGON policy attribute setting, because administrators often want to be able to log in with a password on the system.
