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.

Daily checks are still commonplace for many SAP customers today; with Avantra, they are a thing of the past. These are manual checks that a bot can perform hundreds of times each day. Similarly, a bot can create incidents or notifications when something goes wrong.
For existing solutions, it is necessary to assess to what extent the solution is customised. A modification is the more serious the more time-consuming the maintenance is, including testing, e.g. in the case of upgrades. The fewer customer specifications are available, the more suitable a system or application is for external operation by a service form to be chosen.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
You can make these settings in the SM19 transaction.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
It ensures that the necessary services and foundations are provided for the SAP system and all applications.
