The presentation layer is the top layer of the R/3 SAP Basis system and includes the communication with the user. Here, the data is graphically prepared for the user on the end device by means of software components from the application programs of the application layer. The presentation layer is the interface to the user (SAP GUI).
First you have to create an area menu in the area menu maintenance with the transaction code SE43 or SE43N. Then add the created menu to the SAP standard menu S000.

The security of an SAP system requires protection against unauthorised access, e.g. through the secinfo and reginfo files. A cleanly implemented authorisation concept protects against attacks within the SAP system. However, it is also possible to attack your SAP system via the network. Through the RFC Gateway Server, your system communicates with external servers and programmes. One particularly effective way to protect against this are so-called Access Control Lists (ACL). Find out what this is and how you can use it to better protect your SAP system. The SAP Standard offers different approaches for gate protection. All methods combined can provide even greater safety. For example, it is possible to use Access Control Lists (ACL) to monitor exactly which external programmes and which hosts can communicate with the gateway. Another option is to configure the gateway to support Secure Network Communication (SNC). Finally, there are various security parameters for the gateway. This article focuses on the use of ACL files such as secinfo and reginfo files. What is an ACL? Access control lists are files in which permitted or prohibited communication partners can be recorded. For the gateway to use these ACL files, parameters must be set in the default profile of the SAP system and of course the files must be maintained accordingly. With the help of logs and traces, which can be configured for this purpose, a precise investigation can be made in advance of the activation, which connections currently run via the gateway. This allows them to prevent important applications with which your system communicates from being blocked by the ACL files. The rules in the ACL files are read from top to bottom of the gateway to decide whether to allow a communication request. If none of the rules matches the requesting programme, it will be blocked. Network-based ACL The network-based ACL file contains permitted and prohibited subnets or specific clients.
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.
"Shortcut for SAP Systems" simplifies tasks in the area of the SAP basis and complements missing functions of the standard.

The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
If a program then still has security problems, it can either be released via the dual control principle or returned for further processing.
