Database layer: The database layer contains a database server on which all the data of the SAP ERP system is managed. This includes the database management system (DBMS for short) and the actual dataset. The dataset includes user data and data tables as well as applications and system control tables.
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.

In the SAP product world, the presentation layer is based on several modules that are grouped under the collective term SAP GUI. SAP GUI for Windows, SAP GUI for Java, Web Dynpro for ABAP (WDA) and SAP GUI for HTML ("Web GUI") are widely used.
You can call the SPAM transaction in one of the following ways: Select SAP menu Tools Maintenance Patches. Enter the transaction code SPAM. Features The SAP Patch Manager provides the following features: Loading Support Packages: Requested support packages can be loaded into your system from SAPNet - Web Frontend, SAPNet - R/3 Frontend, or Collection CDs. Inserting Support Packages: Resetting When SPAM inserts a support package into your system, a fixed sequence of steps is followed. If the Support Package implementation stops, you can resume processing at a later time. The operation will resume where it was cancelled.
Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.
Using this tool allowed us to move from manual validation of critical permissions to an automatic process.
