SAP Basis - trends for the coming years
The second component of the application layer is the message server. It acts as a kind of "mediator" between the services and the applications.
The SAP NetWeaver Application Server Add-on for Code Vulnerability Analysis tool, also known as Code Vulnearability Analyzer (CVA), is a tool that performs a static analysis of user-defined ABAP source code to detect possible security risks. The tool is available in the NetWeaver ABAP stack and is based on versions from: 7.0 NetWeaver: in EHP2 SP 14 or higher / 7.0 NetWeaver: in EHP3 SP 09 or higher / 7.3 NetWeaver: in EHP1 SP 09 or higher / 7.4 NetWeaver: in SP05 or higher To use the CVA tool, the execution of system-wide security controls must be enabled with the RSLIN_SEC_LICENSE_SETUP report. Afterwards, the security checks are available in standard ABAP code checking tools such as ABAP Test Cockpit (ATC) or Code Inspector (SCI). The option of these checks is usually referred to as "security analysis in extended program check". Note that the use of the security check feature for custom code separation is licensed and incurs additional costs. The older program that has been around for years is Virtual Forge's "Code Profiler". It is one of the first products in this segment of SAP security and was used by SAP itself for many years. It is very comprehensive and is also able to track individual variables across the entire control flow. This leads to very precise statements and a reduction of false positives.
Analysis
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.
The "Shortcut for SAP Systems" tool is ideal for doing many tasks in the SAP basis more easily and quickly.

In addition, the SAP Basis team can easily implement new functionality in the new system - without compromising the security, stability or quality of the previous function, which would be the case with non-certified and inexperienced people.
