SAP NetWeaver Application Server Add-on for Code Vulnerability
IDOC IDoc and EDI Basis: Repair and Check Programs
From a purely technical point of view, each generated authorization role contains a profile from which a user receives the actual authorization objects and authorization characteristics. If this profile is outdated or not assigned at all, the user will not have all the authorization objects contained in the authorization role. Incidentally, the problem arises particularly frequently after role transports: If an authorization role is changed in the development system and then transported to the production system, the current profile is not automatically assigned to the users with the respective role. A user comparison must therefore be performed here.
The core of the three-layer model is the application layer. This consists of one or more application servers and a message server. Companies use the application server to provide services for the operation of applications in SAP. The message server serves as an "intermediary" between the applications and services, for example, by controlling communication between the individual application servers and determining the load on the application servers. Furthermore, the data is prepared for the user in the application view so that the user can call up the data visually in the presentation layer. At the same time, the user data is forwarded to the database.
Resource management such as memory, buffers, etc
For example, many customer ABAP programs work by uploading or downloading data. There are potentially large security gaps here that allow access to server data. In addition, the widespread direct invocation of operating system commands that are not covered by a self-programmed authorization check is a major problem. Even though classic SQL injection, i.e., the entry of extended SQL commands, is a potential security vulnerability, it occurs rather rarely in SAP systems. More widespread is the unintentional dynamization of SQL calls because input parameters are not sufficiently checked. The need to check all in-house developments internally for such security vulnerabilities before they are delivered in SAP's own code has led to the development of the SAP Code Vulnerability Analyzer tool.
Basis comprises a number of middleware programs and tools from SAP. Basis is responsible for the smooth operation of the SAP Basis system and thus for R/3 and SAP ERP, for example. SAP thus provides the underlying basis (hence the name) that enables various SAP applications to be interoperable and portable across operating systems and databases.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
Also in the course of a conversion to S/4HANA, the data is migrated from the original database type to an SAP HANA database.
SAP Fiori is the next generation presentation layer - a user experience (UX) that is particularly simple and user-friendly.
