In the age of digitisation, the wheel need not be reinvented. Certain functions are consumed or used by platforms only, without fully retaining the necessary infrastructure. In order to participate in this compared to competitors, it is necessary to introduce these technologies, to use them and to learn about their possibilities. Examples include the use of cloud services or applications in the IoT and big data environment.
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.

A secure SAP system does not only include a good role concept. It is also necessary to check whether a user should (still) have a specific role. Regular verification of role assignment is called recertification. In this blog post, I'd like to introduce you to the need for recertifications and our own tool, EasyReCert. The need for recertification - scenarios: Example 1: The "apprentice problem" Imagine the following scenario: A new employee (e.g. apprenticeship or trainee) will go through various departments as part of his or her training and will work on various projects. Of course, an SAP User will be made available to your employee right at the beginning, which is equipped with appropriate roles. As each project and department passes, the employee repeatedly needs new permissions to meet the requirements. After the employee has successfully completed his or her induction and is now in a permanent position, he or she still has permissions that are not necessary to perform his or her duties. This violates the principle of "last privilede" and represents a potential security risk for your company. Example 2: The change of department The change of department is one scenario that probably occurs in every company. If a change of department does not automatically involve a complete reallocation of roles and the employee simply takes his old permissions with him, critical combinations of permissions can occur very quickly. For example, an employee who has permissions in accounts payable and accounts receivable violates the SoD ("Segregation of Duties") principle and poses a potential security risk to your company. Recertification as part of a revision: The two examples above show that a regular review of role allocation identifies potential security risks for your business and can be addressed.
The database layer manages all data in the R/3 System. It contains the database management system (DBMS) and the actual data.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
Synchronisation of Repository Objects (SPAU): Developers must call the transaction SPAU and then match it.
So much information... how can you keep it so that you can find it again when you need it? Scribble Papers is a "note box" that makes this very easy.
On the one hand, it requests data from the database layer, processes it and then passes it on to the presentation layer.
