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.
The presentation layer is the top layer of the R/3 SAP Basis system and includes the communication with the user. Here, the data is graphically prepared for the user on the end device by means of software components from the application programs of the application layer. The presentation layer is the interface to the user (SAP GUI).

The SAP basis as an organisational unit within a growing IT organisation is facing far-reaching changes. The growing number of technologies and the growing need for integration and collaboration with upstream and downstream IT departments means that the SAP basis is constantly growing. Examples of organisational concepts and further information can be found in chapters 7.6 and 9.4 of the Master's thesis.
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.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
SAP Basis refers to the administration of SAP system that includes activities like installation and configuration, load balancing, and performance of SAP applications running on Java stack and SAP ABAP. This includes the maintenance of different services related to database, operating system, application and web servers in SAP system landscape and stopping and starting the system. Here you can find some useful information about SAP Basis: www.sap-corner.de.
Note that once the test scenario has passed, the queue is empty and needs to be redefined.
Whenever you find a red traffic light on the Roles tab in the user master in SU01 - or a yellow traffic light on the Users tab in PFCG, you can usually solve the problem with a simple user synchronization.
