Customising User and Permissions Management
Installing and executing ABAP source code via RFC
You can limit the recording to a specific user. You can also use the trace to search only for permission errors. The evaluation is similar to the evaluation of the system trace in the transaction ST01. In transaction STAUTHTRACE, however, you can also evaluate for specific authorization objects or for specific permission check return codes (i.e. after positive or negative permission checks). You can also filter multiple entries.

Define critical permission combinations that cannot be assigned in the monitored systems. A whitelist allows you to specify which users (such as emergency users) you want to exclude from the evaluation. Identify vulnerabilities in the configuration of your RFC interfaces, i.e. RFC connections, where users with extensive permissions (e.g., the SAP_ALL profile) are registered. These RFC connections can be used for the so-called RFC-Hopping, where access to an SAP system is made via such an extensively authorised RFC connection.
Maintain derived roles
If such information is available from the past, it should be checked whether all topics have been implemented in accordance with the comments. If one or the other recommendation has not been implemented, this circumstance should in any case be documented in a comprehensible manner, or it should be possible to provide a comprehensible justification. However, it is not sufficient to focus only on the improvement potentials that have been presented, because it must be ensured that all those points that have not been criticized in the past will continue to fit. Preparation is made much more difficult if there are no helpful comments or reports from the previous fiscal year, or if it is a first-time audit or a change of auditor. What all does the IT auditor look at during the annual audit? There are topics that every auditor looks at because there are standards for doing so, however it is common for the auditor to perform additional audit procedures in the IT audit depending on the strategy of the overall audit. In this newsletter we want to focus on the most important standard audit topics on the process level and the IT controls defined therein in the context of the SAP® system.

For table logging, it must be ensured that SAP® Note 112388 (tables requiring logging) is fully implemented and that all tables containing financially relevant data are also included in the logging. Of course, this also applies to all Z-tables! As last point of the important parameter settings are those for the definition of the password settings. Here, it should be ensured that the parameters are also set up in accordance with the company's specifications. However, the check should not only focus on the global settings that are valid for all users, but should also include all those users who have been assigned their own security policies. Especially for these, an appropriate justification must be available in writing.

However, if your Identity Management system is currently not available or the approval path is interrupted, you can still assign urgently needed authorizations with "Shortcut for SAP systems".
