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.
Application layer: The application layer is the core of an R/3 SAP Basis system. This layer communicates in both directions, to the presentation layer and to the database layer. The application programs on the application servers request the required data from the database layer, process it, prepare it for the user and pass it on to the presentation layer. Data that the user enters in the SAP GUI is passed on to the database via the application servers.

You can reduce the Queue selection. To do this, select the Support Package that should be the last in the queue. After that, the queue is recalculated. You can also start the recalculation explicitly with Queue. Note that you can only select Support Packages that are part of the software component you have selected (the mouse cursor will change its appearance accordingly). The support packages associated with the calculated queue are green. The highest support package of the previously selected software component is additionally marked with a green tick. The support packages that are no longer part of the queue are still visible in the list and can be selected again. If you want to set the queue for another software component, select New Component. Result You have defined a queue. Now insert the support packages in the queue [page 20]. Rules for the Queue The following rules apply to creating a Queue: If it is an FCS system, the first step is an FCS Support Package. If it is missing from the queue, it cannot be defined. Instead, you will receive an error message telling you the name of the missing FCS Support Package. You cannot insert an FCS support package in a non-FCS system (official state of delivery). Support packages for a selected component are queued in order. If support packages in the queue have connections to support packages of another component (further predecessor relationship, required CRT), the queue will be extended by additional support packages until all predecessor relationships are fulfilled. Note that the SAP Patch Manager takes into account the configuration of your SAP system and only adds support packages to the queue that can be inserted into your system.
