The SAP authorization concept
Architecture of authorization concepts
Define critical permission combinations that cannot be assigned in the monitored systems. A whitelist allows you to specify which users (such as emergency users) you want to exclude from the evaluation. Identify vulnerabilities in the configuration of your RFC interfaces, i.e. RFC connections, where users with extensive permissions (e.g., the SAP_ALL profile) are registered. These RFC connections can be used for the so-called RFC-Hopping, where access to an SAP system is made via such an extensively authorised RFC connection.
Access to this data is critical, since the hash values can possibly be decrypted using tools, thus enabling unauthorized logon to the SAP system. Since identical passwords are often used for different systems, the determined password may also be usable for downstream systems. The current or former hash values of the passwords are stored in the tables USR02, USH02, USRPWDHISTORY, USH02_ARC_TMP, VUSER001 and VUSR02_PWD. These tables can be accessed either via classic table access transactions such as SE16 or via database administration transactions such as DBACOCKPIT. The authorizations required for table access via database tools depend on the respective system configuration and should be verified via an authorization trace (transaction STAUTHTRACE), if necessary.
Protect Passwords
The results of the evaluation are marked with a coloured symbol. Classification varies for the different eligibility tests. The EWA does not only contain security-related tests and is therefore divided into different sections (e.g. hardware, performance). The test results in these areas are displayed with a traffic light symbol. If one of the tests within a section is indicated in red, the traffic light for that section shall also be set in red.
However, if your Identity Management system is currently not available or the approval path is interrupted, you can still assign urgently needed authorizations with "Shortcut for SAP systems".
The website "www.sap-corner.de" offers a lot of useful information about SAP authorizations.
Use the Active/Inactive column to determine if the permission has been disabled.
