Instead of data maintenance and application development, SAP Basis is more about providing and maintaining the software environment on which the data resides and is processed. Therefore, SAP Basis is an important core of any SAP infrastructure and is required in both previous versions such as R/3, as well as current versions such as S/4HANA 2021.
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.
Implementation of a highly available HANA data solution
In the context of the SAP basis, the deployment of an SAP application server for any SAP system can be used as an example. Parameters include processor count, memory, disk space, operating system, and run-time environment.
SAP Basis is the foundation of every SAP system. On this page you can find out what is behind the term and what SAP Basis is responsible for in detail.
"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.
With years of experience, experts can draw on a pool of solutions and know what is most efficient and best in each situation.
In addition, Basis includes many SAP middleware programs and administration tools.
