The typical tasks of system support and administration of an SAP landscape include, among others:
SU53 Display authorization data
Our SAP Basis experts take care of the operation of your systems every day. They ensure that your SAP systems run smoothly and keep performance at its maximum.
It is therefore not unusual for the authorisation allocations to be regularly reviewed in the course of a revision or by external auditors. This is a very laborious process with SAPS standard tools. In this scenario, an authorisation administrator would first have to manually assign each employee to a specific manager and determine their roles. After that, these roles should be exported from the system (for example, to an Excel file) and then submitted to the supervisor so that he can decide whether the role assignment is appropriate or not.
Use of the Security Audit Log
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 are the following reasons that may lead to the termination of this step: TP_INTERFACE_FAILURE: Unable to call tp interface. TP_FAILURE: The tp programme could not be run. For more information, see the SLOG or ALOG log file. CANNOT_IMPORT_DDIC: Unable to import ABAP Dictionary. See the Dictionary Import Log for the cause of the error. AUTO_MOD_SPDD This step checks whether modifications to ABAP Dictionary objects can be adjusted automatically. RUN_SPDD_? This step prompts you to customise your modifications to ABAP Dictionary objects by calling the transaction SPDD.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
