When considering the security of SAP transport landscapes, it is not only the production system that is relevant for auditing. The other systems, including the development systems, must also be included in the risk considerations. The SAP_ALL profile is still frequently used there instead of concrete roles. This article identifies the main risk areas.
After creating a authorization object, you should do the following: Make the permission check implementation at a convenient location in your code. Maintain the proposed values for the application in the transaction SU24. Re-load the role in the PFCG transaction if the application has already been rolled. If it is a new application, adjust the roles by including the new application in the Role menu, and then maintaining the permissions of the authorization objects loaded into the role by the suggestion values.

Configuration validation gives you an overview of the homogeneity of your system landscape. Typical criteria are operating system versions, kernel patch levels, and the status of specific transport jobs or security settings. The following security settings can be monitored using configuration validation: Gateway settings, profile parameters, security notes, permissions. As part of the comparison, you can define rules that determine whether the configuration is rule-compliant or not. If the configuration meets the defined values in the rule, it will be assigned Conform status. You can then evaluate this status through reporting.
The Three Lines of Defense model is used to systematically approach risks that may arise in companies. It integrates operational controls as well as risk management, information security, and internal auditing. It can be used to assess and classify the risks arising from SAP authorizations. The monitoring of risks is incorporated into the processes, so that there is constant control by various bodies. This reduces the risks considerably and ensures a clean authorization assignment.
However, if your Identity Management system is currently not available or the approval path is interrupted, you can still assign urgently needed authorizations with "Shortcut for SAP systems".
At www.sap-corner.de you will also find a lot of useful information on the subject of SAP authorizations.
A permission concept is only as good as the code that performs the permission checks.
The RFC interfaces and associated system users often have too strong authorizations and can quickly be misused by unauthorized persons to view sensitive company data.
