Parameterization of the operating system, the databases and the SAP system to ensure high-performance and trouble-free operation
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.
Protect: CodeProfiler for ABAP protects the SAP system from internal and external attacks from the first day of deployment. The ABAP firewall can be set up within a very short time and immediately checks every new transport request when it is released. Optimize: The audit function of CodeProfiler for ABAP specifically determines which programs are most threatened and should therefore be cleaned up first. In the long term, CodeProfiler for ABAP supports the automated correction of all findings and thus enables the timely closure of security gaps in all programs.
SM02 System message
There was even a case where the SAP environment required a review of the data center power and cooling. At that time, the data center infrastructure had to be upgraded before we could even proceed.

QUEUE_STILL_IN_BUFFER: The queue is not fully processed because incomplete support packages of the queue are still in the transport buffer. CANNOT_RESET_FCS_FLAG: If there is an FCS Support Package (FFD) in the queue, the system will be marked as being at the generally available release level after this support package is inserted. In this case, this operation could not be performed successfully.
"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.
SAP Basis administrators still spend much of their time reviewing their systems or doing project work such as new installations.
To store all the information on the subject of SAP - and others - in a knowledge database, Scribble Papers is suitable.
The SAP Basis system is a kind of operating system of the R/3 system or SAP ERP.
