SAP, as one of the world's leading software providers with over 100,000 employees, represents a central component of their system landscape for many companies. Thanks to the many different modules, such as "Finance" and "Human Capital Management", as well as the wide range of customization options, a broad field of professions and possible areas of focus has opened up here in almost 50 years.
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.
What does SAP Basis Support do?
In every company with an SAP system, there is someone who is responsible for the SAP Basis. This person ensures the trouble-free operation of the SAP system. He or she accompanies maintenance work and intervenes in special situations, such as poor performance. Even for companies that hand over the operation of the basis to an external service provider, there are often still tasks from the user and authorization management environment at this point.
Outsourcing services for your SAP Basis operations offers many advantages. As SAP consultants with many years of expertise in plant engineering, shipping operations, insurance companies, upstream and downstream processes in the petroleum industry, retail, banking and many other industries, you benefit from our "all-round experience" from companies of all sizes, from corporate groups as well as medium-sized businesses.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
