Use of Secure Network Communication
Will Blockchain's Economy and Administration Revolutionise? What is a blockchain? A blockchain is a complete and unchanging transaction history of all transactions of a decentralised community that everyone who is part of it agrees to. The word blockchain first fell in connection with Bitcoin as a decentralised network for payments in the digital currency of the same name. The blockchain describes an underlying technology in which all transactions are publicly and unchangeably recorded. This transaction history is updated periodically. Each participant in the decentralised community accepts it as a reality, stores it on their computer, and can thus ensure at any time that no one can duplicate expenditure, as this would lead to a conflict in the transaction history elsewhere. A peculiarity of blockchain technology is that it has solved the "Double Spending Problem". Double-spending means something that can be doubled, and by 2008, only one central institution was considered to be sustainable. Double Spending can best be understood using the example of an image on a mobile phone. When I upload it to Facebook, I made a copy of it and I can upload it to Instagram, for example. So I used my picture "double". This effect made it impossible to establish a trustworthy, decentralised digital currency by 2008.
SAP administrators are present wherever SAP systems are used. This now applies to many industries and corporate divisions. SAP systems can be found in the areas of accounting, cost accounting, activity-based costing and controlling. In all of these areas, they ensure smooth operation and further development, helping the company to make internal processes more efficient and thus save costs and resources.
SAP Basis refers to the administration of SAP system that includes activities like installation and configuration, load balancing, and performance of SAP applications running on Java stack and SAP ABAP. This includes the maintenance of different services related to database, operating system, application and web servers in SAP system landscape and stopping and starting the system. Here you can find some useful information about SAP Basis: www.sap-corner.de.

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.
Among other things, it determines which application server a user logs on to in order to distribute the workload (load balancing). The message server also enables the individual application servers to communicate with each other.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
For this purpose, there is the RSMEMORY report.
A note box in which data of all kinds can be quickly filed and retrieved. This is what Scribble Papers promises. At first, the program looks very spartan. But once a small structure is in place, you realise the great flexibility of this little helper.
The advantage here is that no additional infrastructure is required; instead, the existing SAP system landscape is used for the entire control and execution without incurring a loss in performance.
