Benefits of this course SAP HANA - Installation and Administration
Personnel planning
Reduce resources: depending on the agreement of the contract, you can ask for the service resources only when needed. This will save you some costs.
For example, many customer ABAP programs work by uploading or downloading data. There are potentially large security gaps here that allow access to server data. In addition, the widespread direct invocation of operating system commands that are not covered by a self-programmed authorization check is a major problem. Even though classic SQL injection, i.e., the entry of extended SQL commands, is a potential security vulnerability, it occurs rather rarely in SAP systems. More widespread is the unintentional dynamization of SQL calls because input parameters are not sufficiently checked. The need to check all in-house developments internally for such security vulnerabilities before they are delivered in SAP's own code has led to the development of the SAP Code Vulnerability Analyzer tool.
Performance Optimization
In order to escape the checks carried out by the iris scanners and ultimately his own arrest, a doctor illegally reuses his eyes and acts under a new identity. With the help of the new eyes he finally succeeds in entering the secured area of the "Precogs" and he can begin his investigation. Through this "biohacking" he not only deceives the biometric security systems - he compromises the highest police control system. All stories!? "Great stories!" think now. But: No one will ever fall for a simple trim. And anyway: Biometric security systems and eye transplantation? It's not for nothing a science fiction movie! What does this have to do with RFC security? All right, I can understand your doubts. But how do you like the following story, for example? RFC Security and the Art of Identity Change Germany, everywhere, 2017: Johannes Voigt has been a medium-sized company employee for several years. He is considered a reliable and conscientious developer from the IT department. In fact, he is increasingly unfairly treated. He decides that he no longer wants to carry his frustration with him.
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 "Shortcut for SAP Systems" tool is ideal for doing many tasks in the SAP basis more easily and quickly.
It also sets measurable targets for the next three years.
The presentation layer is responsible for "presenting" - as the name suggests - the applications and data for the user's work, i.e. presenting them visually.
