Analyzing the quality of the authorization concept - Part 1
Testing Permission
Add SAP Note 1695113 to your system. With this note, the RSUSR200 and RSUSR002 reports are extended by the selection of different user locks or validity. In the selection, you can now distinguish whether you want to include or exclude users with administrator or password locks in the selection. In addition, you can select in the report RSUSR200 whether the users should be valid on the day of selection or not. To do this, select whether you want to select the user locks as set (01 set) or not set (02 not set) in the selection screen of the RSUSR200 report in the Locking after Lock section of the User Locks (Administrator) field. This includes local and global administrator locks. In the same section, you can also select the password locks (false logins) as set (01 set) or not set (02 not set). This will filter for users that are locked because of incorrect password messages and for which a password login is no longer possible. You can select these selection criteria together or separately. Alternatively, you can also use the Use only users without locks option and additionally, in the Selecting after the user is valid between user today and user today, select not valid.
If the proliferation has occurred because the authorization concept was not adhered to, a cleanup is sufficient. If the proliferation has arisen because there are errors and gaps in the authorization concept, these errors must be identified, eliminated and the authorizations optimized. If the concept can no longer be implemented in a meaningful way, or if it has already been set up incorrectly, it will be necessary to create a new one.
Unclear objectives and lack of definition of own security standards
Your SAP system landscape keeps you safe and up-to-date by inserting different types of SAP hints and patches. For a first overview of the security information for SAP systems, see the SAP Service Marketplace at https://service.sap.com/securitynotes. For a complete list of all security advisories for all SAP solutions (SAP NetWeaver Application Server ABAP and Java, TREX, SAP HANA, Sybase, SAP GUI, etc.), see Security Notes Search on this page. The My Security Notes page allows you to find the SAP notes that are relevant for systems registered in SAP Service Marketplace. This does not take into account information already recorded.
Suitable for this responsible task are, for example, department heads or SAP key users who are familiar with all data access options (cross-module, via report, directly to the raw table, etc.) as well as with the organizational and technical protection measures. By signing the data ownership concept, the responsibility should be acknowledged and taken as seriously and bindingly as, for example, the signature under the purchase contract of a house.
Assigning a role for a limited period of time is done in seconds with "Shortcut for SAP systems" and allows you to quickly continue your go-live.
Runtime versions of rolls are not transportable in SAP HANA.
At www.sap-corner.de you will also find a lot of useful information on the subject of SAP authorizations.
Key users should be able to access certain reports regularly, but only read information relevant to their work.
