Assign SAP_NEW to Test
The passwords of the users are stored in the SAP system as hash values. The quality of the hash values and thus their safety, however, depends on the hash algorithms used. The hash algorithms previously used in SAP systems are no longer considered safe; They can be cracked in a short time using simple technical means. You should therefore protect the passwords in your system in various ways. First, you should severely limit access to the tables where the hash values of the passwords are stored. This applies to the USR02 and USH02 tables and in more recent releases the USRPWDHISTORY table. The best way to assign a separate table permission group to these tables is to do so, as described in Tip 55, "Maintain table permission groups". In addition, you should also control the accesses using the S_TABU_NAM authorization object.
Alternatively, the maintenance of the authorization objects can also be called up via transaction SU21 (report RSU21_NEW). On the left side the individual classes and objects can be selected around then to the authorization object the existing authorization fields and short descriptions as well as over the button "documentation to the object indicate" also the documentation to the object to be called can.
User master data
You can also monitor security alerts from the Security Audit Log via the Alert Monitoring of your Computing Centre Management System (CCMS). The security warnings generated correspond to the audit classes of the events defined in the Security Audit Log. Many companies also have the requirement to present the events of the Security Audit Log in other applications. This requires evaluation by external programmes, which can be done via the XML Metadata Interchange (XMI) BAPIs. You must follow the XMI interface documentation to configure it. You can also use the RSAU_READ_AUDITLOG_ EXTERNAL sample programme as a template. A description of this programme can be found in SAP Note 539404.
You can use the Security Audit Log to control security-related events. Learn how to configure it to monitor the operations that are relevant to you. You want to use the Security Audit Log to monitor certain security-related operations or particularly well-authorised users in the SAP system. For example, you can log failed RFC calls system-wide, delete users, or log all activities of the default user, DDIC. For these loggers you need different recording filters and, if necessary, the possibility to select generic clients or users. Therefore, we will show you the settings you can make when configuring the Security Audit Log.
With "Shortcut for SAP systems" you can automate the assignment of roles after a go-live.
What rules should you follow? Introductory projects usually produce a large number of customised programmes without being subjected to a permission check when they are executed.
If user data is present in multiple systems, then the first choice is to automatically create a user through an identity management system, which is resolved by an HR trigger in SAP Identity Management (ID Management).
