Mitigating GRC risks for SAP systems
Solution approaches for efficient authorizations
Additional permission check on the S_RZL_ADM authorization object: For security reasons, an additional permission check is performed on the S_RZL_ADM authorization object for special PSE (Personal Security Environment) files with access type 01 (Create). These files are called *.pse and cred_v2. These files are required for single sign-on, encryption and digital signatures. They are maintained using the transaction STRUST and the transaction STRUSTSSO2, which require the same permission (see SAP Note 1497104 for details).
Incorrect use of the user types and password rules can result in the shutdown of the RFC interfaces. Find out what types of users you can use and how the password rules affect these types of users. In the SAP system, you can choose between different user types when creating users. These user types control the login behaviour and also the impact of password rules on the user. This can lead to undesirable behaviour, especially if the parameter for the validity of the initial password is set. It is often not known that the password rules also apply to users of the communication type. Communication users usually use an initial password because a dialogue is not possible and the password is not changed. If parameters for the validity of the initial password are now also introduced, these also apply to communication users. We will show you how to prevent such problems and give you an overview of the types of users and the impact of the password rules.
Security Automation for HR Authorizations
The direct consequences are overauthorized users, a lack of overview and dangerous security gaps. In order to get the system back on track in the long term, a redesign is usually the most efficient solution. Depending on the requirements and project framework, we also rely on proven software solutions from our partners.
Another important authorization object for background processing is the object S_BTCH_NAM, which allows a user to run the steps of a job under another user (see SM36 -> Edit step). Here, a name other than the user's own can be entered in the user field of a step. The prerequisite is that the job scheduler has an authorization for the object S_BTCH_NAM, which contains the name of the step user, and that the step user exists in the same client as the job scheduler itself. From 4.6C: The step user must be of type Dialog, Service, System or Communication.
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.
The identifier, which can also be called a risk ID, describes a combination of authorization objects with field names and field values.
The website www.sap-corner.de offers a lot of useful information about SAP authorizations.
Both solutions offer you the added value of centralised reporting of existing users, newly created users, and role assignments.
