Analyzing the quality of the authorization concept - Part 1
The selection mask for selecting change documents in the transaction SCUH is divided into four sections: Standard selection (similar to other SUIM reports), output, selection criteria, and distribution parameters. In the default selection you have the option to specify for which model view, for which modifier (Modified by) and for which time period you want to view change documents.
Typically, users access a table's data through applications rather than directly. If so, you should take precautions and restrict access to sensitive data. End users typically do not access table-level data directly, but the data is displayed in business applications and their display is restricted in context by means of entitlement checks. However, there are cases where generic access to tables via the SE16, SE16N, SM30, SM31 or SM34 transaction is required for administrators, key users, verifiers, etc. For example, a verifier should have read access to all customising tables. However, you do not want to display security-related tables. Key users should be able to access certain reports regularly, but only read information relevant to their work. There are several ways to restrict access to tables by using table tools. This means that users can only access tables or table contents that they want to see. However, we would like to point out that the granting of permissions for these tools in the production environment is considered to be critical to security, since it is very easy to allow access to large amounts of sensitive data in the case of erroneous or excessive permissions. Therefore, only apply these permissions in a restricted way.
User master data
A mass rolling out of rolls is a very useful thing. It is also possible to use Excel-based data - as in the case of the outlined application case with eCATT - because it is a one-time action for the roles considered and SAP standard programmes are used in the background. However, ongoing maintenance of the permissions system, with continuous changes to roles and their detail permissions, requires the mapping of much more complex operations. An exclusive control over Office programmes should be well considered. This does not mean, of course, that there are not very good partner products for the care of roles. Simply verify that SAP standard procedures are used and that authorisation is managed in accordance with SAP best practices.
By clicking on the Registration Data button, you start the RSUSR200 report and you enter the selection mask. This report allows you to select users by login data. You can also determine if a user has changed his initial password. You can select a predefined variant from the catalogue using the button (Get variant) or the key combination (ª) + (F5).
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
In this case, all reverse-loaded change documents shall be taken into account.
We can point out discrepancies, including drill-down to user/client level, directly.
