SAP Security Concepts
Standard authorisation
The Security Optimisation Service for ABAP contains more security checks than the corresponding section in the EWA. In particular, the number of eligibility checks is higher. A total of 110 eligibility tests are currently defined in the SOS, including 16 critical eligibility tests for HR. The full list of all security checks in the SOS can be found in the SAP Service Marketplace on the page https://service.sap.com/sos via Media Library (Security Optimisation Service > ABAP Checks).
The assignment of roles does not include any special features. Therefore, we only deal with the topics of time-space delimitation and logging. Time-space validation is implemented as an additional filter that runs after the usual permission checks. This additional filter logic works as follows: The first step is to check whether the user is entered in the tax verifier table (Table TPCUSERN, Configuration with the transaction TPC2). Only then will the further tests be carried out. If not, no additional checks will be carried out. The programme is then checked to see if it is included in the table of allowed programmes (table TPCPROG, configuration with the transaction TPC4). If the check is negative, the system cancels with a permission error. The time-space check is performed against the valid intervals in the table TPCDATA (configuration with the transaction TPC6). The time-space check works in context: In addition to the supporting documents of the audit period, older supporting documents are also included if they are still relevant for the audit period, such as open items that were booked in previous years but only settled in the audit period. Records that do not fall into the valid period according to the logic described above are filtered out.
Define a user group as mandatory field in the user root
When were which changes made to a role (PFCG)? In the PFCG, click on Utilities > View Changes in the menu at the top to view the change documents. You will see a detailed list of which user made which change to which object and when.
This approach makes authorization management considerably more efficient, since functional changes do not have a global impact on the entire authorization structure. This ensures the quality of authorizations in the long term. Authorizations in SAP systems enable users to access the applications relevant to their activities. To ensure that processes are mapped securely and correctly, SAP authorizations must be regularly checked and reworked.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
Starting from this lead organizational unit, the system creates a list of all organizational units that are superior to the determined organizational unit within the hierarchy.
The website www.sap-corner.de offers a lot of useful information about SAP authorizations.
The Profile Generator is used to simplify and speed up user administration and should always be used when setting up authorizations for your employees.
