Add New Organisation Levels
If there are no buttons for copying and pasting in the PFCG transaction, you can simply insert them. Only seven lines are displayed in the dialogue box to maintain field values to properties in transaction PFCG. Up to now it was not possible to insert more than these seven lines at once from the clipboard. However, this may often be necessary in the context of the maintenance of permissions, for example if you want to use entries from other roles. Read how to copy and paste the buttons in the dialogue box to maintain field values to the authorization objects.
The permission checks are logged as part of the system trace in transaction ST01. It records all permission checks and validated permission values for a specific application server, and specifies, depending on the client, whether the permission checks were successful or not. The Trace display has now been improved (see also SAP Note 1373111).
Security Automation for HR Authorizations
In the SAP system, passwords are locked when the maximum number of allowed password login errors is reached. This counter is reset with a password each time you successfully log in. In addition, an initial password can be locked when its validity has expired. Both the validity of the initial password and the maximum value for password login errors are set using profile parameters. For details, see Tip 4, "Set password parameters and valid passwords characters". A password lock only prevents a user from logging in via his password, because the number of errors is only evaluated if the login is done by password. If a login is now made via other authentication methods (such as SSO), these are not affected by the password lock. This also applies to internal expiration procedures (such as background jobs) because you do not need to register a password. This prevents, for example, denial-of-service attacks, which first cause a password to be locked in order to block internal processes. Eine Ausnahme von dieser Regel gibt es allerdings: Auch wenn andere Authentifizierungsverfahren genutzt werden, prüft das System, ob der Benutzer dazu in der Lage ist, sich mit einem Passwort anzumelden. Wenn dies der Fall ist und das Passwort gerade geändert werden muss, wird diese Änderung vom Benutzer abgefragt. Diese Abfrage können Sie aber auch mithilfe des Profilparameters login/password_change_for_SSO ausschalten.
In addition to defining permissions for external RFC access through the S_RFC authorization object, it is possible to prevent external calls to function blocks. From SAP Net-Weaver AS ABAP 7.40 there is the additional SAP Unified Connectivity (UCON) layer. It controls external access to RFC function blocks independently of users or roles and can be configured to suit your needs. All function modules that are to be executable via RFC are entered into the UCON Communication Assembly. If a function block is not stored there, the call will be blocked. UCON has been designed to minimise impact on RFC call performance. The necessary function blocks are identified in the UCON Phase Tool (transaction UCONPHTL), which constantly monitors all external RFC calls and supports an introduction of the UCON Communication Assembly. This allows calls to new function blocks (such as custom developments, support package changes) to be analysed and, if necessary, released for external access. In addition, UCON offers the possibility to review the configuration in an evaluation phase. There are approximately 40,000 RFC-enabled function blocks in an ERP system; Usually no more than a few hundred of them are used. With the use of UCON you therefore increase the security of your system.
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.
