SAP Basis - trends for the coming years
Backup concepts
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.
Within the framework of an innovation team or test laboratory to be created, it is necessary to admit ideas outside of the SAP basis or to consciously use other sources of ideas within and outside the company. These may include business units, external service providers, universities or series of lectures on specific topics.
SAP BASIS AS A SERVICE
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.
If you get a tp-step in the cancel message, it is a transport order-independent step whose logs cannot be displayed with logs. In this case, analyse the following files: tp-Step 6: P tp-Step N: N tp-Step S: DS All protocols are located in /usr/sap/trans/log.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
However, the tasks also include strategic and planning aspects.

Rejected Transport Order Tip: Leave the status on Rejected, remove the rejected transport order from the import queue, if necessary, and follow the next steps.
