LANDSCAPE MANAGEMENT
The coverage of old core tasks (such as security or compliance) and new core tasks (such as cloud or mobility) must be increased in the sense of a holistic consideration. This means that certain tasks must be considered not only in the context of the SAP basis, but also in the overall context.
How does a blockchain build consensus? Once you decide to send a payment to someone, you must use the Private Key to "sign" it (in German: signature). This means nothing other than that you specify another public address to which you want to send the money and confirm this transaction with your own private key. You don't have a central authority to send the information to, you're going to spread the information to all the other Miners around you. The miners then forward this information to other miners, who in turn do the same. This exponential wave of information reaches the entire network of the distributed community within a few milliseconds. Every time a miner receives a transaction, it checks that the transaction is actually correct. It checks which private key has signed, which public address the transaction should go to and whether the sender has enough "coins" for this transaction. What are consensus mechanisms? Any miner that solves a transaction through complex mathematical calculations is rewarded by the sender with a "fee" (transaction fee). How will it be decided which miner will receive the transaction fee? Because only one can get this reward. Also, what happens when you try a double spending by sending one transaction to one miner and then another transaction with the same money to another one millisecond later? These two could not yet exchange and thus information would be different in the network.
SAP technologies
SAP SE offers various training courses and certifications for SAP Basis administrators and SAP Basis consultants. As an alternative to internal recruitment and training, companies can also turn to external consultants or even outsource the entire SAP Basis administration to an external team with experience in SAP Basis.
Another way to secure your gateway using the SAP standard is to encrypt communication using Secure Network Communication (SNC). In the case of unprotected data communication paths between different client and server components of the SAP system that use the SAP protocol RFC or DIAG, the data exchange takes place in plain text and there is a risk that this can be read. With the help of SNC, you can create end-to-end encryption (E2EE), which can be used to secure communication between two components, such as between the application server and SAP GUI. In addition, SNC encryption provides the basis for using SAP Single Sign-On (SSO) as a security solution, which significantly reduces the internal effort of password management.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
With an 'X' in this three-digit switch value you can now explicitly specify at which position in the user name no wide spaces and control characters may occur.
The website www.sap-corner.de offers many useful information about SAP basis.
It contains one or more application servers and a message server.
