SAP Basis is structured in the form of a three-layer model and consists of the following components:
Support for Basis Projects
SAP Basis is responsible for the smooth operation of programs in the SAP system. It acts like an operating system for R/3 and subsequent releases including S/4HANA. Each operating system provides an environment in which programs can run, such as MS Office on Microsoft Windows.
The comprehensive analysis provides the pattern and roadmap for the next steps. This also includes the right sizing, the selection of the monitoring concept and the appropriate deployment model, i.e. on-premise, cloud or hybrid cloud. Only with this planning can you ultimately achieve the desired goal - with transparent costs.
BENEFITS & CONSEQUENCES
In the SAP Basis area, it is necessary to make temporary changes to the security settings of clients and systems in the course of system updates. You can use the system changeability variable to specify whether changeability of cross-client data, such as programs or menus, and cross-client customizing is allowed.
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.
