Displaying sensitive data
Checking at Program Level with AUTHORITY-CHECK
SAPCPIC: SAPCPIC is not a dialogue user, but is used for EDI usage in older releases (EDI = Electronic Data Interchange); in default, SAPCPIC has permissions for RFC access. However, you should not use this user for them, nor for batch processes, but you must create other users for these applications. Safeguard measures: Lock down the user, change the password, assign it to the SUPER user group and log it with the Security Audit Log.
The downloading of the table must be monthly. You can also make downloading easier; Frank Buchholz presents programmes that you can use in his blog (see http://wiki.scn.sap.com/wiki/display/Snippets/Show+RFC+Workload+Statistic+to+build+authorizations+for+authorization+object+S_RFC). Optionally, the next step is to identify function groups for the function blocks. You can find them in the AREA field of the ENLFDIR table. However, we recommend granting permissions at the function block level, because function groups often contain a large number of function blocks and the accessibility is expanded unnecessarily.
WHY ACCESS CONTROL
The four important concepts of SAP security first require a certain amount of effort. They not only have to be coordinated, formulated and made available, but also continuously updated and, above all, actively implemented. Nevertheless, the return on investment is high, because they prepare for all eventualities, provide audit security, and also offer a high level of protection for the SAP system and thus for the company itself.
If you get into the situation that authorizations are required that were not considered in the role concept, "Shortcut for SAP systems" allows you to assign the complete authorization for the respective authorization object.
You can also find some useful tips from practice on the subject of SAP authorizations on the page "www.sap-corner.de".
Furthermore, a tool would be useful to give you an overview of the tables for which a user is entitled.
