Evaluation of the authorization check SU53
Criticality
With the introduction of security policy, it is now possible to define your own security policy for System or Service users. This way you can ensure that backward-compatible passwords are still used for these users. This eliminates the reason that password rules were not valid for System/Service type users; Therefore, the rules for the content of passwords now apply to users of these types. Password change rules are still not valid for System or Service type users. If you are using security policy in your system, you can use the RSUSR_SECPOL_USAGE report to get an overview of how security policy is assigned to users. This report can be found in the User Information System (transaction SUIM). In addition, the user information system reports have added selected security policies to the user selection. This change was provided through a support package; For details, see SAP Note 1611173.
It is very important that critical authorizations are generally subject to a monitoring process in order to be able to ensure that they are assigned in a productive system in a very restricted manner or not at all. Law-critical authorizations in particular, such as deleting all change documents, debugging ABAP programs with Replace, and deleting version histories, must never be assigned in a production system, as these authorizations can be used to violate the erasure ban, among other things. It must therefore be ensured that these authorizations have not been assigned to any user, not even to SAP® base administrators.
Authorization check
Configuration validation gives you an overview of the homogeneity of your system landscape. Typical criteria are operating system versions, kernel patch levels, and the status of specific transport jobs or security settings. The following security settings can be monitored using configuration validation: Gateway settings, profile parameters, security notes, permissions. As part of the comparison, you can define rules that determine whether the configuration is rule-compliant or not. If the configuration meets the defined values in the rule, it will be assigned Conform status. You can then evaluate this status through reporting.
However, the preferred and more comprehensive variant of a programmatic permission check is the use of the AUTHORITY_CHECK_TCODE function block. This function block not only responds to a missing permission when the programme starts, but can also specify that only the NO-CHECK check marks maintained in the transaction SE97 allow external calling from another transaction context. This is determined by the function block and not by the developer.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.

Once you have identified the organisational features to consider, verify that you can redesign the existing roles so that the organisational features can be clearly maintained by use.
