What to do when the auditor comes - Part 2: Authorizations and parameters
Context-dependent authorizations
Single sign-on (SSO): This solution is useful if you have not yet used SSO for your SAPS systems or if not all SAP systems are integrated into the SSO solution. In such cases, you must implement the Web application in a system that supports SSO logins, such as Central User Management (ZBV), SAP Identity Management (ID Management), or Active Directory (AD).
Once you have edited the role menu, you can customise the actual permissions in the PFCG role. To do this, click the Permissions tab. Depending on the quantity of external services from the Role menu, the authorization objects will appear. The authorization objects are loaded into the PFCG role, depending on their suggestion values, which must be maintained for each external service in the USOBT_C and USOBX_C tables. You can edit these suggested values in the SU24 transaction. Make sure that external services in the Customer Name Room also have the names of external services and their suggestion values in the tables maintained (see Tip 41, "Add external services from SAP CRM to the proposal values"). Visibility and access to external services is guaranteed by the UIU_COMP authorization object. This authorization object consists of three permission fields: COMP_NAME (name of a component), COMP_WIN (component window name), COMP_PLUG (inbound plug).
Define a user group as mandatory field in the user root
We therefore recommend that you schedule a background job on the PFUD transaction, which performs a regular user comparison (see Trick 17, "Schedule PFUD transaction on a regular basis"). By the way, did you know that the auth/tcodes_not_checked profile parameter enables you to disable the transaction startup permissions for the SU53 and SU56 transactions? To do this, enter the value SU53, SU56, or SU53 SU56 for the profile parameter. This means that the end user no longer needs the permissions to run these transaction codes from the S_TCODE authorization object.
The report RSUSR008_009_NEW (List of users with critical permissions) is provided starting with SAP Web Application Server 6.20 with the following support packages: Release 6.20, starting with SAPKB62039 Release 6.40, starting with SAPKB64003 You can continue using the old reports RSUSR008 and RSUSR009 until release 6.40. The RSUSR008_009_NEW report is delivered with the old SAI proposals for critical credentials already used in the RSUSR009 report.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".

You can then run the report with your respective check scope and the corresponding critical authorization or combination variant and check in which roles or users such violations exist.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
