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.

The past ten years have primarily revolutionized the infrastructure and database layer. The fascinating thing is that there have been hardly any changes to the SAP installation program SAPinst during this time.
Following the recommendation of dividing the SAP basis into an application-orientated and infrastructure-related SAP basis [A4], Figure 3 shows a possible presentation form. The SAP-Basis interface function is structured into a SAP basis, which is close to the application and is responsible for coordination and communication with vertical and higher IT specialist and business areas, and a SAP basis close to the infrastructure. The infrastructure-related SAP basis in turn serves as the link between the application-orientated SAP basis and the infrastructure levels. Subject Matter Experts will perform the link task again. In the application-orientated SAP basis, in turn, technology architects are more likely to be placed. The innovation activity or innovation team aspect of the SAP basis is placed at the level of the SAP basis, which is close to the application, because the existing capabilities allow it to assume a leading, also coordinating role and acquire expertise both by adding the SAP basis near the infrastructure and the downstream IT departments.

Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.
Many errors are avoided: Far fewer errors occur, e.g. when enhancement packages are installed, if this is done by SAP experts.
In this case, the workprocess goes into PRIV mode.
