What do RFC interfaces and RFC security have to do with the play "Hauptmann von Köpenick" and the science fiction film "Minority Report"? Probably more than you like! RFC security and theatre?! Germany, Berlin, 1906: The 46-year-old cobbler Wilhelm Voigt dreams of returning to a normal life. After various convictions and many prison stays, he lives on the margins of society. It's not just the money he lacks. Above all, the lack of access to his social system makes him. In view of his impasse, he opts for a drastic measure. The excluded shoemaker pulls off and grates off several junk dealers to assemble a military uniform gradually. A few days later, he slips into the same disguise, successfully changes his identity and then swings through Berlin as Captain von Köpenick. He commandeers soldiers, storms the town hall and even detains the mayor. There is no doubt about the commands and their execution, because their true identity is veiled: Because of a simple disguise. A disguise that gives him all the necessary permissions he needs for his scam. At the end of the day, Wilhelm Voigt successfully compromised the Berlin government. RFC Security and Science Fiction?! USA, Washington, DC, 2054: The Washington police have long since stopped investigating murders: It prevents the killings right in advance. For this purpose, so-called "precogs" are used, which use precognition to predict and report murders in visions before they happen. At the same time, the government uses a system of public scanners that can identify all citizens clearly at any time by iris detection. One day, when policeman John Anderton himself appears as the culprit in a vision of the "Precogs," he flees the police building and decides to find out why.
Once you sent the money person A and once person B. Which miner is right now? The solution is to divide the consensus into time blocks, in which a miner is randomly selected, and then determine which transaction it has selected as the consensus during this block. The transactions are stored in blocks of the chain. Only a limited number of transactions fit into each block. The miner, which solves the last transaction of a block before a new one is generated, also gets a bitcoin as a reward.

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.
The SAP Basis Plug-In is backward compatible and follows the release and maintenance strategy of the SAP R/3 Plug-In. SAP delivers it together with the SAP R/3 Plug-In. For more information, see SAP Service Marketplace at basis-plug-in → SAP Plug-In → SAP Basis Plug-In → Releases.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
This SAP training covers the introduction/basics of SAP administration.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
This person ensures the trouble-free operation of the SAP system.
