Without this provisioning component, adjustments to employee permissions in the respective IT resources would have to be implemented by the relevant system administrators. However, manual provisioning processes are by their very nature a source of errors. If an employee's tasks change, the system administrator should consider all active user accounts when modifying and deleting accounts. A modern IDM system therefore helps companies to keep track of users and their permissions, especially in complex and heterogeneous system landscapes.
The so-called SAP message server also belongs to the application layer. Only one instance of this server exists in the system. It mediates between the services and applications. In concrete terms, this means that the message server takes care of load balancing and determines, for example, on which application server a user logs on. Communication between application servers is also the domain of this message server.
Planning / Implementation
This is the heart of the SAP system. In the classic three-tier model, this would be the logic or control layer. One or more application servers host the necessary services for the various applications on this layer. These application servers provide all the services required by the SAP applications. In theory, a single server could fill this role. In practice, these services are in most cases distributed among several servers, each serving different applications.
Another way to secure your gateway using the SAP standard is to encrypt communication using Secure Network Communication (SNC). In the case of unprotected data communication paths between different client and server components of the SAP system that use the SAP protocol RFC or DIAG, the data exchange takes place in plain text and there is a risk that this can be read. With the help of SNC, you can create end-to-end encryption (E2EE), which can be used to secure communication between two components, such as between the application server and SAP GUI. In addition, SNC encryption provides the basis for using SAP Single Sign-On (SSO) as a security solution, which significantly reduces the internal effort of password management.
"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.
In order to ensure the necessary expertise both in the direction of application and application-related IT departments as well as in the direction of infrastructure units, the SAP basis should be divided into an infrastructure-related SAP basis and an application-orientated SAP basis.
To ensure that the system is available at all times, an SAP Basis team ensures its smooth operation.
