Security Automation for SAP Security Checks
You can now assign transactions to these roles. Experience has shown that roles should remain application-specific and that a distinction between book or investing, changing and reading roles is also useful. There will be regular transactions used in multiple roles. You should not overestimate the often demanded freedom of redundancy. However, for critical transactions or transactions that are involved in a functional separation conflict, it is recommended that they be kept in a separate role. In general, roles should not contain too many transactions; Smaller roles are easier to maintain and easier to derive. Also, assigning them does not quickly lead to the problem that users have too many permissions. If you keep the necessary functional separations in place, you have already prepared them as a takeaway.
You can't keep an eye on everything. Therefore, avoid that your colleagues do not assign users to a user group, and thus ensure that the user master data maintenance permissions check is correct. You do not want a user without a user group to be able to be created in your SAP systems? Users without a user group can be changed by all administrators with permission for any user group. You should also prevent incomplete permission checks when assigning roles and profiles to users without a permission group. Because it is possible to assign roles and permissions to a user first, and then assign a user group that does not have permission to assign roles and profiles. Finally, do you want to change the user group for an existing user without having permission for the new user group? In the following section we will show you how to secure your user master data maintenance.
Role Management
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.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.
At "www.sap-corner.de" you will also find a lot of useful information on the subject of SAP authorizations.
The German Federal Office for Information Security has compiled detailed information on defining critical authorizations.
