In order to ensure the necessary expertise both in the direction of application and application-related IT departments as well as in the direction of infrastructure units, the SAP basis should be divided into an infrastructure-related SAP basis and an application-orientated SAP basis. The infrastructure-based SAP basis acts as a contact level and point of contact for IT departments such as virtualisation, storage management and databases. The application-orientated SAP basis serves as the contact and coordination level for application-related topics. BUILDING OVERARCHING EXPERT TEAMS WITH SAP basis INVOLVEMENT To reduce organisational friction points as well as to optimally handle selected topics, it is recommended to set up expert teams with the participation of the SAP basis. These teams of experts can be virtually organised and therefore of temporary duration and consist of participants from all relevant IT disciplines or business areas. If the topic of the virtual group of experts is the focus of the SAP basis, the SAP basis will take over the management and control of the expert team.
Critical business processes require a secure, efficient and stable operation of an SAP system landscape. High demands on the management as well as the operation of the underlying SAP NetWeaver platform require competent support in all tasks of planning, support and updating of the SAP Basis. The increase in installed components as well as systems integrated via interfaces expands these needs. Only with professional care and maintenance of its components can SAP NetWeaver bring its advantages as an integrative platform to bear.

The SAP Basis & Technology department deals intensively with SAP technologies and their application. The possibilities and limits are investigated and corresponding specifications and tools are developed in order to use the technologies profitably. The results and findings are made available to the other alogis areas and implemented in real-life customer projects.
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.
