List of required organisational levels and their value
In the foreground, important SAP reports on the subject of role and authorization administration were presented. Since these and the entire SAP system are known to be based on ABAP coding, the analysis of the source code is just as important, especially when using in-house developments. These in-house developments often present serious security vulnerabilities because they have insufficient authorization checks in the coding. To search for explicit strings and to categorize the in-house developments accordingly, the report RS_ABAP_SOURCE_SCAN can be used. This allows existing programs in the backend to be explicitly checked for specific check patterns by the authorization administrator and any errors to be corrected by the relevant developers. Authorization-relevant check patterns for such a scan are, for example, "AUTHORITY-CHECK" or SQL statements such as SELECT, UPDATE or DELETE. The former checks whether authorization checks are present in the source code at all. The check for Open SQL patterns analyzes the code structure for direct SELECT, MODIFY or INSERT statements that must be avoided or protected on the authorization side. The best practice measure in this case is to use SAP BAPIs. The preventive best practice would be to involve developers and authorization administrators equally during the conceptual design of the custom development.

Each UI component that can be clicked corresponds to an external service that must each have permission set up. UI components also include creating or calling stored searches or navigating from one record directly to another record, such as calling an appointment directly from a business partner; This corresponds to cross-navigation. All navigation options in the form of external services are defined in the customising of the CRM business role in the form of a generic outbound plug mapping to the navigation bar. Outbound Plugs (OP) define what happens when a user leaves a view in SAP CRM. Here the customising is set for scenarios that do not necessarily fit all CRM business roles. The corresponding CRM business roles have been configured to be associated with outbound plugs that are not required for the respective CRM business role scenario. This explains the large number of external services in the role menu.

You should therefore enforce cryptographic authentication and communication encryption by setting up Secure Network Communication (SNC). SNC provides a strong cryptographic authentication mechanism, encrypts data transmission, and preserves the integrity of the transmitted data. For some time now, SNC is freely available without a SSOMechanism (SSO = Single Sign-on) for SAP GUI and the RFC communication of all SAP NetWeaver customers. You should always implement SNC between SAP GUI and application server, as this communication can also run over open networks. For RFC communication, you need an SNC implementation if you think the data transfer could be intercepted.

There are many advantages to using an authorization tool for companies. These include: - Managing authorization requests - Distributing and assigning authorizations - Auditing authorizations - Developing authorizations. With the help of authorization tools, it is possible, for example, to drastically reduce the effort required for role creation and authorization management through concrete assignment of SAP system roles.

With "Shortcut for SAP systems" you can automate the assignment of roles after a go-live.

These RFC connections can be used for the so-called RFC-Hopping, where access to an SAP system is made via such an extensively authorised RFC connection.

SAP delivers authorization objects for Records and Case Management, which you can use to control access to records, cases, documents, and incoming mail items for individual organizational units in your organizational plan in conjunction with corresponding Customizing settings.
