Application of SNOTE and elimination of errors
Another important example is the reading permission for TemSe objects. The temporary files are often forgotten, because it is often not considered that cached (strictly) sensitive data, which is intended for only one user (owner), can be viewed by another user without permission - and across clients. The examples mentioned show us how important it is to carefully assign permissions for client-independent transactions. Download Transaction tables The transactions that enable the examples above, including certain expressions of the associated permission objects and our recommendations for them, can be found in the file "Critical cross-client permissions" for download. Other client-independent transactions are located in the Cross Clients TCODES file. The criticality of these transactions should be assessed according to the context. I recommend always being careful and keeping these transactions in mind.

By using a code scanner, it is now possible for every developer to scan for complex security patterns during the extended check of his program, which tell him whether he has built vulnerabilities into his program. These vulnerabilities are detected and can now be addressed in a workflow-driven process. Currently, there are two products that can support customers in the area of scanning their own SAP programs.
SAP Administration I
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.

Some useful tips about SAP basis can be found on

In the context of the SAP basis, the deployment of an SAP application server for any SAP system can be used as an example. Parameters include processor count, memory, disk space, operating system, and run-time environment.

The "Shortcut for SAP Systems" tool is ideal for doing many tasks in the SAP basis more easily and quickly.

Full planning, including hardware sizing, is therefore essential.

A note box in which data of all kinds can be quickly filed and retrieved. This is what Scribble Papers promises. At first, the program looks very spartan. But once a small structure is in place, you realise the great flexibility of this little helper.

Miners try to integrate the transactions into a block.
