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.
You would like to know more about what is happening on your SAP systems - then I recommend that you take a closer look at the Solution Manager Usage Procedure Logging (UPL) functionality. What code is often executed? Which database tables are accessed regularly? What unused developments exist? - The UPL provides answers to these questions. You can implement the functionality into your existing SAP landscape without additional licence costs and with moderate effort. What information does the UPL provide? Usage Procedure Logging is used to log and record user behaviour data roughly comparable to the ST03N workload statistics. UPL is able to record the call and execution of the following ABAP objects: Reports Functional Blocks Classes Methods Subroutines SQL Calls In addition, UPL is able to detect dynamic programme calls and generate transparency about the modifications used. All usage data is recorded in detail and automated and, if desired, made available centrally in the SAP Solution Manager. Benefits 1) Hardly measurable Performance Impact 2) Central collection of data of all systems in the SAP Solution Manager's BW 3) No complex setup 4) Once activated, the collector and extractor jobs run regularly and without further manual activities Possible usage scenario If you have Solution Manager 7.2 in use, you can use UPL within the framework of "Custom Code Lifecycle Management" (in German: management of customer developments). After one activation of the BW content and some standard jobs, you select one or more systems for which you want to activate UPL. If you already have the SP05 installed, there is a separate "Guided Procedure" for configuring the UPL in SOLMAN_SETUP.
Server Administration
Instead of data maintenance and application development, SAP Basis is more about providing and maintaining the software environment on which the data resides and is processed. Therefore, SAP Basis is an important core of any SAP infrastructure and is required in both predecessor versions such as R/3 and current versions such as S/4HANA 2021.
It is therefore not unusual for the authorisation allocations to be regularly reviewed in the course of a revision or by external auditors. This is a very laborious process with SAPS standard tools. In this scenario, an authorisation administrator would first have to manually assign each employee to a specific manager and determine their roles. After that, these roles should be exported from the system (for example, to an Excel file) and then submitted to the supervisor so that he can decide whether the role assignment is appropriate or not.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
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.
If all miners accept the correctness of a completed block, they will all work the next one immediately.
This allows permission administrators to use their valuable time to correct the errors rather than just looking for them.
