Potential security risks in application processes in IDM systems
SAP Basis: the heart of the SAP system
In order to make a transaction in cryptocurrencies, you do not have to let your bank know about it as you would for "normal" money, but you have to use the Private Key to prove that you own the coins. The transaction looks like a piece of the puzzle. Half of the puzzle piece consists of information about the coin set, time and public address of the sender or receiver. The other half is the signature of the private key belonging to the sent public address. Both halves make this piece unique. Changing only one piece of information would completely change the whole transaction or the appearance of the puzzle piece. This transaction is transferred to the network or to the miner and is checked for correctness first. If everything fits, the transaction will be sent to other miners who will do the same. Otherwise, the transaction is ignored. Miners try to integrate the transactions into a block. This is called mining and we have described it so that the miners put the puzzle pieces together into a puzzle (block). A small part of a block to be integrated follows from the block that was previously mined. If all miners accept the correctness of a completed block, they will all work the next one immediately. The puzzle (block) is fixed and is irrevocably connected to the block before or after. The blocks form a chain and are called blockchain, which contains all the transactions that have ever been made and is visible and unchangeable by everyone. In doing so, blockchain replaces a central institution and avoids double-spending, which ultimately gives value to a cryptocurrency. Smart Contracts The biggest advance compared to Bitcoin and similar applications is that second-generation blockchains, such as Ethereum, use the so-called Turing-Complete script language Solidity. This enables calculations to be made within the blockchain. While Bitcoin allows only rudimentary multi-signature functions, Ethereum opens the door to much more complex operations called smart contracts. Smart contracts are contracts in which a decentralised blockchain ensures their unchangeability and execution.
The definition, organisational structure as well as the naming of the SAP basis is historically conditioned by previous SAP software versions and components. This also results in the perception of the SAP basis and the related focus of the SAP NetWeaver and the ABAP system core, which is still widely used today. However, the scope of activities has changed significantly in terms of tasks and technology and will continue to change in view of SAP's perspective and product strategy and the changing roles of IT. In order to accommodate this change and to change perceptions both in the overall context of the SAP ecosystem and within its own company, the SAP basis must develop a new self-understanding and establish a marketing for the publication of its own performance. The underlying information can be found in the master thesis in chapters 7.4 and 9.2.

In some cases, the term SAP Basis is also equated with the administration of an SAP system, i.e. with a task description. In this case, it refers to the management and control of SAP systems via various administration and monitoring tools.
Due to the variety of tasks and the high level of complexity, I find my job extremely exciting. There are very many constellations of SAP systems and databases. Each installation, migration and update brings new aspects and challenges. It is precisely these challenges that are important to me, so that I can continue to learn and develop professionally on a daily basis.
Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.
A collaborative approach between departments and IT technology is required to assess IT technical and business benefits.
In the last few years, I have been asked time and again what SAP Basis is and what we SAP Basis administrators do in our daily work.
