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.
Another important example is the reading permission for TemSe objects. The temporary files are often forgotten, because it is often not considered that cached (strictly) sensitive data, which is intended for only one user (owner), can be viewed by another user without permission - and across clients. The examples mentioned show us how important it is to carefully assign permissions for client-independent transactions. Download Transaction tables The transactions that enable the examples above, including certain expressions of the associated permission objects and our recommendations for them, can be found in the file "Critical cross-client permissions" for download. Other client-independent transactions are located in the Cross Clients TCODES file. The criticality of these transactions should be assessed according to the context. I recommend always being careful and keeping these transactions in mind.

Supervision, monitoring SAP® and interface systems
As an interface to the user, the presentation layer contains software components (the SAP GUI) by means of which the user is presented with the application. During its runtime, an SAP GUI component is always permanently linked to a user logon to the NetWeaver AS ABAP.
Why should we even have an individual SAP Security Check performed? Your SAP authorisation concept is designed to ensure the security and protection of data against unauthorised access and abuse. The technical complexity of SAP systems and the ongoing adaptations of business processes often lead to unknown security vulnerabilities. In addition, the increasing digital networking with business partners offers further attack points on your SAP system. SAP Security Check gives you an overview of the security situation of your SAP systems. This will identify potential risks that could jeopardise the safe operation of your IT landscape. Your starting situation The ongoing changes in your IT systems lead to unrecognised security vulnerabilities and your auditors will regularly report to you in the final report on abuses in the authorisation concept. The legal requirements (e.g. EU guidelines) to secure your business processes and IT systems have not yet been implemented and the increasing networking with business partners presents new challenges to your security system. The security-related system settings and permissions settings applied to your SAPS systems are poorly documented, which in many cases causes the system settings to allow extensive critical access unchecked. Critical SAP permissions, profiles, and roles identify permissions that allow critical operations to be performed in terms of security or from a legal or business perspective are called "critical permissions" by SAP. The granting of critical allowances must therefore generally be carried out with particular care and should therefore be planned in advance. Technical and organisational measures and processes must then ensure that the desired level of safety is implemented.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
When you develop these applications, you should think about securing them early.
