Advantages of authorization concepts
Risk: historically grown authorizations
In addition to SAP book recommendations on SAP authorizations, I can also recommend the books from Espresso Tutorials such as "SAP Authorizations for Users and Beginners" by Andreas Prieß * or also the video tutorial "SAP Authorizations Basics - Techniques and Best Practices for More Security in SAP" by Tobias Harmes. Both are, among other media, also included in the Espresso Tutorials Flatrate, which I have also presented in more detail under SAP Know How.
Is it necessary for your evaluations to select the blocked or invalid users? This is now directly possible with the extensions of the user information system. There is always a requirement to evaluate the existing users in your SAP system. Examples may include lists requested by auditors. In such a case, you naturally want to exclude invalid users and those with administrator lock from the selection. Up to now, you have had to perform various evaluations with the reports RSUSR200 and RSUSR002 of the user information system (transaction SUIM) and subsequently edit the lists. The findings may not have been accepted by the auditors as the lists were visibly manipulated, even if this manipulation was justified. You can now enter this selection directly. We will show you below how to search for users with password or administrator lock or exclude them from your selection.
Translating texts into permission roles
It is essential to implement adequate authorization checks in every ABAP development. For this purpose, the so-called AUTHORITY-CHECK is used, which queries the required authorization object characteristics and thus only allows authorized users to execute the code.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.
You can also find some useful tips from practice on the subject of SAP authorizations on the page "www.sap-corner.de".
Note that the global check variant of the Code Inspector that you created in the transaction SCI and that is entered as the default in the transaction ATC (ATC configuration) includes the security tests of the extended programme check of the SAP Code Vulnerability Analyser.
