Our SAP Basis trainings and courses originate from our practical work in companies. All SAP Basis trainings for system administration and administrators are conducted by SAP certified experts, who know what they are talking about, because they mainly realize SAP projects at our customers.
If all financial and sales activities as well as production, logistics and the personnel administrators run via one system, measures must be taken to ensure reliable functioning on the one hand and to protect the system internally and externally on the other. Due to the long history, the increased availability requirements often do not match the actual protection measures, so that security risks often arise at this point.
Preparation of the migration to the SAP HANA database
Projects: Your SAP Basis administrator plays a key role in planning and executing system upgrades and migrations. He is also responsible for transport management and tests software updates to ensure they are compatible with the landscape. In addition, he must ensure that they are installed in the correct order.
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.
"Shortcut for SAP Systems" simplifies tasks in the area of the SAP basis and complements missing functions of the standard.
FME = One of these special characters may occur at any position in the user name (this corresponds to the default setting, i.e. as if no entry was maintained in PRGN_CUST for the switch).
The abap/heap_area_total parameter defines how much private storage all workprocesses can use in total.
