Schedule PFUD transaction on a regular basis
Limit character set for user ID
SAP NetWeaver 7.31 introduces a new method for determining affected applications and roles by timestamping (see tip 45, "Using the timestamp in the transaction SU25"). With the Support Package 12 for NetWeaver Release 7.31 and Support Package 4 for NetWeaver Release 7.40 from SAP Note 1896191, the Expert Mode function for taking SU22 data for step 2 has been added.
Here, too, it is possible to create security and an overview with the help of tools for HR authorizations. The tool creates a clear overview of which data certain users are allowed to access in the SAP system. Based on this, it is possible to develop automatic checks that run in the background and regularly monitor whether changes to authorizations have created critical gaps in HR.
When defining the development policy, you should ensure that the appropriate attention is paid to access security. Customised programmes or customisations in the SAP Code Inspector ensure that all developers working in the company comply with these guidelines. Verification of compliance with the development directives should be an essential part of quality assurance before the programmes are used productively. The SE38 and SA38 transactions should not be allocated in the productive system and custom programmes should be included in own transaction codes. Permissions are then set up only for these transactions.
The system checks direct access to the contents of tables, for example, with transactions SE16, SM30, or SE16N with authorization checks on a table authorization group, object S_TABU_DIS. If there are no suitable authorizations for the table authorization group, the system checks the name of the table or view, object S_TABU_NAM. When making changes to client-independent tables, the system also checks the authorizations for object S_TABU_CLI. If you have configured line-based authorization checks in Customizing, the system also checks authorization object S_TABU_LIN. Assign tables or views to a table authorization group using transaction SE11 or SE54. You can also define table authorization groups using transaction SE54. If your customer development implements direct access to a table, use the VIEW_AUTHORITY_CHECK function module to perform the authorization check. For more information about generic access to tables, see SAP Note 1434284 Information Published on SAP Site and the online documentation for the authorization objects mentioned above.
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.
This entry only forces a permission check on S_PATH and the ALL permission group; You should, however, only grant such permission very restrictively.
Like all other security issues, SAP authorizations must be integrated into the framework used.
