Performance optimization
The Advanced Memory thus contains mainly user contexts of different work processes, if these cannot be loaded completely into the roll area. Since the storage area is accessible for all work processes, the work processes can also access external user contexts that lie here. In addition, the Advanced Memory contains a global area where data can be stored independently of user contexts. The extended memory size is determined by the values of em/initial_size_MB and em/global_area_MB. The first parameter determines the size of the storage area in which user contexts can be stored, and the second determines the size of the global area. Parameters for Private Storage Last but not least, there is the private storage, which is only used when the user context of a work process has used up all the other storage areas available to it, i.e. its share of the extended memory and its rolling area. In this case, the workprocess goes into PRIV mode. A workprocess in private mode is bound to its current user context and will not become free for other tasks until the current request is completed. If it has used up all the private memory allocated to it, the workprocess will then be restarted and the memory released. This behaviour is controlled with the abap/heaplimit parameter. At times, the user context may exceed the value of abap/heaplimit. The parameters abap/heap_area_total, abap/heap_area_dia and abap/heap_area_nondia define an upper limit for private storage. The abap/heap_area_total parameter defines how much private storage all workprocesses can use in total. The parameters abap/heap_area_dia and abap/heap_area_nondia, on the other hand, determine how much private storage a single (non-)dialogue workprocess can use.
In addition to scanning and identifying the respective security vulnerabilities of a program, it is also possible to stop tasks that are to be transported to other SAP systems with security vulnerabilities in the further transport process This applies, for example, to the CHARM process based on SAP Solution Manager. This forces a programmer to securely check the programs he or she is responsible for according to the same security criteria. If a program then still has security problems, it can either be released via the dual control principle or returned for further processing. Do you know of any other solutions for improving ABAP code security or have you already gained experience with the products mentioned above? I look forward to your comments!
Default Scenario
The core of SAP Basis is the application layer with one or more application servers and a message server. The message server is used for communication between the application servers and transmits jobs between them. The application layer communicates with the database layer on the one hand and the presentation layer on the other. The applications on the application server request the required data from the database, process it and prepare it for the user, who displays it in his Graphical User Interface (GUI) via the presentation layer. Conversely, the application server passes information that the user enters via the GUI on to the database.
All the roles that contain the string "ADM" are considered critical, as they usually refer to administrative roles. When identifying critical SAP permissions, profiles and roles, it should be noted that SAP does propose a concept for names, but this is not always taken into account by applications or its own developments.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
In addition to the optimisation potential of Security Automation, which I explained in more detail in my last post, the E-Learning division also offers numerous possibilities for automation.
Finally, there are various security parameters for the gateway.
