SAP System Monitoring
He has already gathered a lot of helpful information from the day-to-day business in his department: Johannes knows the RFC interfaces and the corresponding technical RFC users from his work with the applications. He also quickly got the password for various RFC users via the radio ("As long as passwords are only communicated by phone and never exchanged in writing, we are clean!"). And that the RFC users are generously entitled even in productive systems is no longer a secret ("Better to have more permissions than too little; the RFC connections have to run, otherwise there is trouble from the specialist areas!"). Since Johannes has access to the SE37 as a developer, it is not a problem to get the necessary access using the function block BAPI_USER_CHANGE - disguised as RFC User. In short, it changes the user type of a technical RFC user in a production system from to by calling the function block.

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.

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.

"Shortcut for SAP Systems" is a PC application that simplifies or even facilitates many activities in the SAP basis.
