User & Authorization Management with SIVIS as a Service
Basics SAP Authorizations including Fiori - Online Training
Describing all configuration options would exceed the scope of this tip. If you need explanations about a customising switch that are not listed here, look for the relevant note about the SSM_CID table. All settings described here can be made via the transaction SM30. You must consider that all settings in the SSM_CUST, SSM_COL, and PRGN_CUST tables are client-independent; only the settings of the USR_CUST table depend on the client.
By adding certain SAP standard reports and the user information system ("SUIM"), you can quickly identify security-relevant issues and correct any errors. This improves basic management of your existing security concept and protects you against external and internal intrusions. If you need help with your system analysis, please feel free to contact us. Xiting offers you a wide range of services related to SAP Security. Above all, our proprietary security tool, the Xiting Authorizations Management Suite, or XAMS for short, allows you to build a new role concept based on your usage data and even generate a revision-compliant security concept at the push of a button. Why not see for yourself and join one of our many different webinars.
Displaying sensitive data
In addition to defining permissions for external RFC access through the S_RFC authorization object, it is possible to prevent external calls to function blocks. From SAP Net-Weaver AS ABAP 7.40 there is the additional SAP Unified Connectivity (UCON) layer. It controls external access to RFC function blocks independently of users or roles and can be configured to suit your needs. All function modules that are to be executable via RFC are entered into the UCON Communication Assembly. If a function block is not stored there, the call will be blocked. UCON has been designed to minimise impact on RFC call performance. The necessary function blocks are identified in the UCON Phase Tool (transaction UCONPHTL), which constantly monitors all external RFC calls and supports an introduction of the UCON Communication Assembly. This allows calls to new function blocks (such as custom developments, support package changes) to be analysed and, if necessary, released for external access. In addition, UCON offers the possibility to review the configuration in an evaluation phase. There are approximately 40,000 RFC-enabled function blocks in an ERP system; Usually no more than a few hundred of them are used. With the use of UCON you therefore increase the security of your system.
For the assignment of existing roles, regular authorization workflows require a certain minimum of turnaround time, and not every approver is available at every go-live. With "Shortcut for SAP systems" you have options to assign urgently needed authorizations anyway and to additionally secure your go-live.
