Our SAP Basis trainings and courses originate from our practical work in companies. All SAP Basis trainings for system administration and administrators are conducted by SAP certified experts, who know what they are talking about, because they mainly realize SAP projects at our customers.
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.

A simpler option is to output the transactions used by the expert as a list and to obtain an overview of the task areas. The function block SWNC_COLLECTOR_GET_AGGREGATES is very suitable for exporting the used transactions in a list. As an alternative, one can directly use the workload monitor in the transaction code ST03N.
However, the system modifiability has no influence on customising changes that are customised by the client. If you want to set the customising changes to customise, you must go to the client control. You can achieve this either by pressing the button "Client Control" when changing the system or by calling the table T000 via the transaction SM30. If you are now in the list of clients, you can double-click on the respective row to jump into the settings of the respective client. Here you can also make the desired settings and save them. Step-by-Step Tutorials System Modifiability (Customising Settings and Repository Objects that are independent of the client) Call the SE06 and click on "System Modifiability". Adjust the desired objects and global setting, depending on your request. Save the changes. Client control (custom customising settings) Call the T000 table in the SM30. Double click on the desired client. Change the settings here depending on your request. Save your changes.
