The presentation view is used to visualize the applications and data for the user. The presentation is done with the help of a graphical user interface (GUI). Furthermore, the presentation view consists of several modules, which are also summarized as SAP GUI. SAP Fiori is the presentation layer of the next generation and is therefore particularly user-friendly.
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.
SAP Basis as a job title
An SAP HANA system lives on applications. When you develop these applications, you should think about securing them early. Using HTTPS instead of HTTP is one of the basics. In addition, you ensure secure authentication and implement a Secure Software Development Lifecycle to ensure backup in your own developments. In your applications, you better start to check them for risks early on and run this backup process regularly. You can analyse and restrict access to source code later. Create a risk register and address security vulnerabilities in a risk-based manner. The later you discover a risk, the more expensive the fix will be. Further information on SAP Security in addition to the article can be found here. Do you have any further questions or suggestions concerning this topic? Would you like us to go further on the subject? I look forward to your feedback!
The database layer manages all data in the R/3 System. It contains the database management system (DBMS) and the actual data.
"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.
In addition to the definition of the service to be provided, the clear description shall include the identification of disclaimers and conditions that must exist.
The default value of the profile parameter is 1, so the weak hashes are generated for each user.
