STAUTHTRACE System trace for authorization checks
From a purely technical point of view, each generated authorization role contains a profile from which a user receives the actual authorization objects and authorization characteristics. If this profile is outdated or not assigned at all, the user will not have all the authorization objects contained in the authorization role. Incidentally, the problem arises particularly frequently after role transports: If an authorization role is changed in the development system and then transported to the production system, the current profile is not automatically assigned to the users with the respective role. A user comparison must therefore be performed here.
In order to cope with the digital transformation in general, but also to cope with the changing demands on the SAP basis and its scope of responsibility, it is necessary to revise existing roles and define and establish new roles. These include the roles of the technology architect, new features of the Subject Matter Expert (SME), and the role of the Expert Team Lead in leading a group of experts. Further information can be found in chapter 7.1 and 9.3 of the Master's thesis.
The administration of SAP Basis
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.
