Preparation of migration to SAP HANA
GUIDE TO THE DEVELOPMENT OF A MARKETING CONCEPT
User authentication is usually performed by entering a user name and password. This information is called user credentials and should only be known to the user, so that no third party can gain access to the system under a false identity. This post explains how a user's password protection can be circumvented and how to prevent it. SAP system legacy data The login data of a user, including password, are saved in the USR02 database table. However, the password is not in plain text, but encrypted as a hash value. For each user there are not only one but up to three generated password hashes. Different algorithms are used to calculate these values, but only the Salted SHA1 can be considered sufficiently safe. Table deduction USR02 The secure password hash is located in the fifth column of the pictured table deduction with the heading Password hash value. The corresponding data field in the column is called PWDSALTEDHASH. Weak Password Hash Risks You have a good and working permission concept that ensures that no processes or data can be manipulated or stolen. A potential attacker now has the ability to read out your database with the password hashes. The hash values are calculated using password crackers, which are available on the Internet at home, and the attacker now has a long list of user credentials. To damage your system, the user will now search for the appropriate permissions and perform the attack under a false identity. Identifying the actual attacker is virtually impossible. Check if your system is vulnerable too Your system generates the weak hash values if the login/password_downwards_compatibility profile parameter has an unequal value of 0.
Every SAP system evolves over many years. It grows and changes with the company. The more functions are mapped in it and the more data is stored, the greater the importance of and dependence on this central ERP system. There is no such thing as a standard SAP Basis solution. It is developed individually with reference to the company.

In addition, the applications prepare the data in such a way that the user can visually capture it via the presentation layer. Conversely, the application server transfers all data that a user enters via the presentation layer to the underlying database.
In the default scenario, the support packages in the queue are fully loaded. In the event of an error, you will not be able to resume and complete the playback successfully unless the error(s) are resolved. Prerequisites The queue is already defined. Procedure To set the scenario you want, select Additions Settings. Select the desired scenario. Select Insert Support Package Queue. You can also use this function to restore an aborted commit procedure. The status bar provides information on the progress of the commit and the latest steps of the SAP Patch Manager. During the recording, you may get into the modification comparison (SPDD, SPAU). If you are playing with the default scenario, you must immediately perform the comparison of Dictionary objects (transaction SPDD), whereas when you compare Repository objects (transaction SPAU), you have the choice to skip it first and perform it later (modification comparison [page 22]). The mode is blocked while a Support Package is being introduced. To avoid repeated login, open a second mode before inserting the queue.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
The unprotected system does not have any limitations on the external services that may register, and there are no rules for running programmes.
So much information... how can you keep it so that you can find it again when you need it? Scribble Papers is a "note box" that makes this very easy.
This is achieved by integrating live data such as configuration settings and defined rules directly from the connected system.
