Authorization check
Evaluation of the authorization check SU53
Certain SAP authorizations, including those for table maintenance (S_TABU_*) require special attention for data protection reasons. These are known as critical authorizations. In the course of authorization planning, a company should determine which authorizations are to be considered critical, which roles may receive which critical authorizations or values for critical authorization fields, and so on. The German Federal Office for Information Security has compiled detailed information on defining critical authorizations.
The password lock is not suitable to prevent the login to the system, because it does not prevent the login via single sign-on. Learn how to safely lock the system logon. The SAP system distinguishes several reasons for blocking. Therefore, sometimes there is confusion when a user is still able to log on to the system, e.g. via Single Sign-on (SSO), despite the password lock. We explain the differences between locking passwords, locking and validity of user accounts, and validity of assigned permissions in the following.
Create permissions for customising
This approach makes authorization management considerably more efficient, since functional changes do not have a global impact on the entire authorization structure. This ensures the quality of authorizations in the long term. Authorizations in SAP systems enable users to access the applications relevant to their activities. To ensure that processes are mapped securely and correctly, SAP authorizations must be regularly checked and reworked.
SAP*: The SAP* user is part of the SAP kernel, and since it is hard-coded in the SAP system, it does not require a user master set. If there is no user master set for SAP*, anyone can log on to the SAP system after rebooting with this user, as the default password will then apply. The user thus has access to all functions, since Authority Checks in this case do not take effect. You can prevent this behaviour by setting the login/no_automatic_user_sapstar profile parameter to 1. If you want to copy clients, you have to set this parameter to 0 again before you do so, because the user SAP* is required for this. Safeguard measures: Despite the parameter setting, the SAP user should have a user master set in all clients. However, you should remove all profiles and lock the user. In addition, change the password, assign the user to the SUPER user group, and log it with the Security Audit Log.
During go-live, the assignment of necessary authorizations is particularly time-critical. The "Shortcut for SAP systems" application provides functions for this purpose, so that the go-live does not get bogged down because of missing authorizations.
By excluding the GENERIC_OP_LINKS folder, you only need to take care of the external services and their authorization objects configured in the CRM business role in your PFCG role.
