Use automatic synchronisation in central user management
Checking at Program Level with AUTHORITY-CHECK
Access to this data is critical, since the hash values can possibly be decrypted using tools, thus enabling unauthorized logon to the SAP system. Since identical passwords are often used for different systems, the determined password may also be usable for downstream systems. The current or former hash values of the passwords are stored in the tables USR02, USH02, USRPWDHISTORY, USH02_ARC_TMP, VUSER001 and VUSR02_PWD. These tables can be accessed either via classic table access transactions such as SE16 or via database administration transactions such as DBACOCKPIT. The authorizations required for table access via database tools depend on the respective system configuration and should be verified via an authorization trace (transaction STAUTHTRACE), if necessary.
Of course, you can also use the data obtained with the permission trace (with filter for the S_DATASET authorization object) to express permissions on the object itself. In any case, you should also use the values obtained for the PROGRAM field. In this way, you exclude misuse by modified copies of ABAP programmes. This limitation of access programmes already represents a security gain, even if you do not want to restrict access to paths and files.
Security within the development system
In the transaction SU01, enter a non-existent user ID and click the Create button (F8). The BAdI BADI_IDENTITY_SU01_CREATE is called with the new user ID. Implementation in the BAdI is running. For example, here you can read additional attributes to the new user from an external data source. The data collected within the BAdIs is written into the fields of the transaction SU01. This will show you the new user master set with the pre-filled fields. You can edit the user master record, such as assign roles, or change the pre-populated fields.
In the area of group consolidation, an authorization concept ensures that no data can be deliberately manipulated, for example to change balance sheets. This can prevent significant financial or reputational damage to banks and stakeholders. Furthermore, access to financial data of subdivisions of a group, such as individual business units or companies, must be restricted to those employees who are allowed to access it because their current activities require it. As a result, a controller of a business unit, for example, can only view the consolidated figures of his business unit, but not the figures of the entire group. Further authorization roles are required, for example, for external auditors. These auditors check all the figures for the entire group, but may only have read access to this data.
Authorizations can also be assigned via "Shortcut for SAP systems".
The Trace display has now been improved (see also SAP Note 1373111).
