Monitoring the remote access from SAP on application-level (Part 3.8)
In a cloud environment (Software-as-a-Service), the software is usually not maintained by the customer, but by the software/cloud provider.
Remote access to the SAP S/4HANA Cloud system for e.g. incident management or software maintenance by the SAP vendor is restricted, approved by management, and removed in a timely manner. Access to the SAP Support IDs is appropriately controlled when IDs are not in use.
Application ‘Display Technical Users’ displays all technical users from SAP that are available in the customer system and the related SAP support request logs. Using the Incident ID, it is possible to display more information about when and why SAP Support Users requested a user for a customer system in the past twelve months:
Note 1: Column “Customer User” displays if SAP user used authorizations from a customer user.
Note 2: Access with the _SAPxxx users is only possible via special URLs, which are not reachable outside of SAP, therefore customers cannot access those technical user accounts.
Note 3: Technical users are only used on SAP side for defined activities. SAP Support User can only request a user if there is a valid and open customer ticket in place. It is not possible to bypass this process.
Using the Security Audit Log (SAL), the last log-on of the SAP technical users can be monitored. The SAL is per default activated in the SAP S/4HANA cloud system (for details please read blog post part 2 “SAP S/4HANA Cloud, public edition – Secure by Default”).
After the auditor has determined whether SAP employees had access to the productive customer system in the audited period, it should be evaluated, if the access to the SAP user accounts was reviewed by the customer timely after the fix / maintenance was completed.
Note: There is no explicit approval by the customer after SAP did a change in the productive system. This is done implicitly when opening a customer ticket to SAP. The review of the activities by the customer is solely a customer internal process to ensure, that only authorized and appropriate changes were conducted and that the impact on the Internal Control System is evaluated.
The access of SAP users to customer productive systems in case of e.g. incidents in also covered in the SOC1 type 2 report. For details please refer to our blog article Service Organization Controls Report Review (Part 4) | SAP Blogs.
Using the SAP Help portal, it is possible to get further information about the access levels and access categories for the SAP support to customer systems (https://help.sap.com/docs/SAP_S4HANA_CLOUD/55a7cb346519450cb9e6d21c1ecd6ec1/3cdb582583b342fd82b3caf3f3763af8.html):
