Conceptual support for the architecture of system landscapes
System updates
A first important step was the introduction of playbooks to professionalize our work. At that time, SAP installation manuals were real tomes with hundreds of pages that often went round in circles and were anything but easy to understand....
Presentation layer: The presentation layer is the interface to the users. With the help of SAP GUI, the data is graphically prepared here and made available to the user on the screen. Furthermore, the data newly collected here is passed on to the application programs of the application layer.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
Type linkage
In order for your SAP system landscape to function permanently, it requires error-free installation and regular support. You can rely on these services:
An important area of SAP Security is the analysis of the customer's own SAP programs, which are classically written in the proprietary SAP language ABAP. Here, too, as in all programming languages, security vulnerabilities can be programmed - whether consciously or unconsciously. However, the patterns of security vulnerabilities in ABAP code differ from those in Java stacks or Windows programs. The goal of these conventional programs is usually to either crash the program (buffer overflow) or to artificially execute the program's own code (code injection). Both is not possible in ABAP, since a crash of a process causes nothing else than the creation of an entry in the log database (Dump ST22) and a subsequent termination of the report with return to the menu starting point. So a direct manipulation as in other high level languages or servers is not possible. However, there are other manipulation possibilities.
"Shortcut for SAP Systems" simplifies tasks in the area of the SAP basis and complements missing functions of the standard.
In addition to internal security requirements, national and international guidelines sometimes require all audit and security-related user actions to be recorded.
The freeware Scribble Papers puts an end to the confusing paper chaos. The tool is also suitable for storing, structuring and quickly finding text documents and text snippets of all kinds in addition to notes.
Especially in larger companies, which also have multiple locations in different countries, it is often necessary to grant different employees the same permissions for different levels of organisation, such as accounting circles.
