Authorization concept - user administration process
For an authorization concept, a clear goal must be defined that is to be achieved with the help of the concept. This should list which regulatory requirements the respective system and the associated authorization concept must take into account. In this way, the legal framework is defined, which is a legal necessity for successful implementation.
We advise you not to use the self-set password with a self-service as a generated password is more secure. The password is generated depending on the password rules; This is done by first evaluating the settings in the security policy assigned to the user. If no security policy has been assigned to the user, the system will consider the password rules in the profile parameters and in the customising table PRNG_CUST. In order for the associated security policy to be considered, you may need to include the correction provided with SAP Note 1890833. Remember that the BAPI_USER_CHANGE function block does not automatically unlock the user. In the event of a lock-out due to incorrect logins, you still have to unlock the user using the BAPI_USER_UNLOCK.
System Security
There are several ways to view the implementation of permission checks: Either you jump directly from the system trace for permissions to the appropriate locations in the programme code, or you go over the definition of the authorization objects. To view the permission checks from the permissions system trace, start the trace from the STAUTHTRACE transaction and run the applications you want to view. Now open the evaluation of the Trace. In the Programme Name column, you can see the programme that includes the Permissions Check. Double-click to go directly to the code site where the permission check is implemented.
The assignment of combinations of critical authorizations (e.g., posting an invoice and starting a payment run), commonly known as "segregation of duties conflicts," must also be reviewed and, if necessary, clarified with those responsible in the business departments as to why these exist in the system. If compensating controls have been implemented for this purpose, it is helpful if the IT department also knows about this so that it can name these controls to the IT auditor. The IT auditor can then pass this information on to his or her auditor colleagues.
Authorizations can also be assigned via "Shortcut for SAP systems".
In most cases, the different rules according to which the risks of SAP authorizations are assessed are problematic.
You can also find some useful tips from practice on the subject of SAP authorizations on the page www.sap-corner.de.
Another problem is that the proof of use of the authorization object is limited to finding implementations of the authorization object.
