Analyse and evaluate permissions using SAP Query
WHY ACCESS CONTROL
Your SAP system landscape keeps you safe and up-to-date by inserting different types of SAP hints and patches. For a first overview of the security information for SAP systems, see the SAP Service Marketplace at https://service.sap.com/securitynotes. For a complete list of all security advisories for all SAP solutions (SAP NetWeaver Application Server ABAP and Java, TREX, SAP HANA, Sybase, SAP GUI, etc.), see Security Notes Search on this page. The My Security Notes page allows you to find the SAP notes that are relevant for systems registered in SAP Service Marketplace. This does not take into account information already recorded.
When creating the PFCG individual roles in the respective SAP system, you should create the menu structure so that they can be combined with other individual roles in a single role. Once you have created the individual roles with the correct role menu, you can assign them to a collection role. Add the Role Menu to the Collect Roll using the Read Menu button. The menu can now be finally sorted. If changes to the roll menu are necessary, however, you must first make them in the individual rolls and then remix them in the roll roll (using the Mix button, see figure next page above). Transactions from other SAP systems such as SAP CRM, SAP SCM etc. can also be integrated into the NWBC. To do this, you first create the PFCG role for the relevant transactions in the target system. From the individual roles you can create collection roles with a defined menu structure.
Authorization concept - user administration process
In the simulation overview you will now receive all the information you already know from the authorisation maintenance in the transaction PFCG. The results are presented in a table where each row corresponds to a value interval of a permission. The Object column specifies the authorization object. Use the Active/Inactive column to determine if the permission has been disabled. The Maintenance Status and Update Status columns provide information about the status of the permission and how the permission has been updated. In the Permissions Comparison column, you can find out what exactly changed on the permission, such as whether a permission has been deleted or added anew, or whether the field values in the permission have been updated. You can find information about the field values in the Value Comparison column, which shows whether values have remained the same, whether they have been added or deleted. The values that were actually deleted and added can be seen in the columns from Value to Value (see figure next page). Please note that this is only a simulation. You must still perform the actual mixing process in the permission maintenance. Because reel mixing is not only a factor in upgrade work, the transaction SUPC also provides the ability to call this simulation mode. In the overview of the selected rolls you will find the button Mix which simulates the mixing process.
The S_RFCACL authorization object is removed from the SAP_ALL profile by inserting SAP Note 1416085. This notice is included in all newer support packages for the base component; This affects all systems down to base release 4.6C. The reason for this change is that the S_RFCACL authorization object, and especially the expression "total permission" (*), is classified as particularly critical for its fields RFC_SYSID, RFC_CLIENT and RFC_USER. These fields define from which systems and clients or for which user IDs applications should be allowed on the target system. Thus, the overall authorisation for these fields allows the login from any system and client or for any user and thus creates significant security risks.
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".
Whether it's recertification of SAP users, vacation requests or birthday wishes: all these things can now be processed and managed centrally in one place.
At www.sap-corner.de you will also find a lot of useful information on the subject of SAP authorizations.
Here I had to look for a moment at which point for SAP key users and not only for the SAP Basis in the SAP system an authorization is callable and may like to take this as an opportunity to write here in the article a few basics on the "anatomy" of SAP authorizations.
