SAP Authorization Concept
This access method depends solely on the rights assigned to the user. System users: Users of this user group are comparable to SAP*. They act as administrator in the system. Therefore, they should be deactivated / set to inactive as soon as possible, as soon as the system operation is ensured. You should still be aware of the SAP ERP environment to address this security risk. In a HANA system, there are privileges instead of permissions. The difference is first of all in terms of terminology. Nevertheless, the permissions are assigned differently (directly / indirectly) via the assignment of roles. These are thus accumulations of privileges. As in older SAP systems, system users must be disabled and certain roles that already exist must be restricted. Compared to an SAP ERP system, small apps are allowed instead of large applications. In this case, attention should be paid to an individual authorisation. It should be a matter of course for users to have implemented secure password rules. Settings Securing the system also means securing the underlying infrastructure. Everything from the network to the host's operating system must be secured. When looking at the system landscape, it is striking that the new technology brings many connections that need to be secured. The SAP Gateway, which is responsible for the connection between backend and frontend, is also a security risk and must be considered. All security settings of existing and future components must be validated to HANA compatibility. Secure communication of connections is obtained when you restrict access where possible. Encryption of the data of a HANA system is disabled by default. Be sure to encrypt sensitive data anyway. Especially data that is archived. If an attack is made on your system, you should be able to run forensic analysis, so you should enable the audit log. Moreover, few users should have access to it.
In order to ensure the stability of the systems and to reduce the risk through proprietary developments, release and patch management must be implemented. Standardised procedures can help to introduce proprietary developments, such as test strategies or service level agreements (SLAs). It is also important to align the productivity setting of customer applications with the maintenance windows and RTO (Recovery-Time-Objective).

You can control the access rights as usual. The big advantage of CMC tab configuration is that you can easily grant or withdraw group access to specific tabs. This gives you the ability to prepare background access permissions and then unlock all permissions by clicking on the CMC tab configuration. On the other hand, this allows you to remove accesses without having to edit any existing permissions. Have you already experienced CMC tab configuration or have questions about the application? I welcome any suggestions you may make as a comment.
Many companies are struggling with the introduction and use of secinfo and reginfo files to secure SAP RFC gateways. We have developed a generator that supports the creation of the files. This blog post lists two SAP best practices for creating the secinfo and reginfo files to enhance the security of your SAP gateway and how the generator helps you do this. secinfo and reginfo Request generator Option 1: Restrictive procedure In the case of the restrictive solution approach, only in-system programmes are allowed. Therefore, external programmes cannot be used. However, since this is desired, the access control lists must be gradually expanded to include each programme required. Although this procedure is very restrictive, which speaks for safety, it has the very great disadvantage that, in the creation phase, links which are actually desired are always blocked. In addition, the permanent manual activation of individual connections represents a continuous effort. For large system landscapes, this procedure is very complex. Option 2: Logging-based approach An alternative to the restrictive procedure is the logging-based approach. To do this, all connections must be allowed first by the secinfo file containing the content USER=* HOST=* TP=* and the reginfo file contains the content TP=*. During the activation of all connections, a recording of all external programme calls and system registrations is made with the gateway logging. The generated log files can then be evaluated and the access control lists created. However, there is also a great deal of work involved here. Especially with large system landscapes, many external programmes are registered and executed, which can result in very large log files. Revising them and creating access control lists can be an unmanageable task. However, this process does not block any intentional connections during the compilation phase, which ensures the system will run non-disruptively.
