Security within the development system
Define critical permission combinations that cannot be assigned in the monitored systems. A whitelist allows you to specify which users (such as emergency users) you want to exclude from the evaluation. Identify vulnerabilities in the configuration of your RFC interfaces, i.e. RFC connections, where users with extensive permissions (e.g., the SAP_ALL profile) are registered. 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.
Typically, this includes permissions that can be used to delete change records in the system or electronically erase them. The traceability of changes is also important in the development system, which is why the authorizations listed below should only be assigned very restrictively or only to emergency users.
Coordinate authorisation management in customer-owned programmes
Finally, we want to give you some recommendations for securing file access. The SPTH table allows you to protect the file system from ABAP programme accesses without granting permissions and to deliberately define exceptions. The problem is identifying the necessary exceptions. However, because the SPTH check is always performed together with the S_DATASET object check, you can use a long-running permission trace to find the paths that are used with filters for the S_DATASET authorization object. The procedure for this is described in detail in our Tip 39, "Maintain suggestion values by using trace evaluations". If you are using applications that access files in the DIR_HOME directory without a path, such as the ST11 transaction, you must specify access to the allowed file groups individually (e.g. dev_, gw_), because there is no wild card for DIR_HOME.
The Security Audit Log (SAL) has ten different filters in the current releases, which control which events are logged. You can configure these filters via the SM19 transaction. The events are categorised as uncritical, serious or critical.
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".
With Managed Services, you receive professional management and improvement of your SAP authorizations.
You also need permissions to maintain the authorization objects in customising the result and market segment calculations.
