Introduction: -


In this Article we will discuss about the Service “Azure Sentinel for SAP Solutions” delivered by Microsoft and how we can take benefit from this service.

Microsoft Sentinel is a scalable, cloud-native solution that provides:

  • Security information and event management (SIEM)

  • Security orchestration, automation, and response (SOAR)


Microsoft Sentinel delivers intelligent security analytics and threat intelligence across the enterprise. With Microsoft Sentinel, you get a single solution for attack detection, threat visibility, proactive hunting, and threat response.

Microsoft Sentinel is your bird's-eye view across the enterprise alleviating the stress of increasingly sophisticated attacks, increasing volumes of alerts, and long resolution time frames.

  •  NPLK900271 - After importing this TR you will get role -/MSFTSEN/SENTINEL_CONNECTOR which needs to be assigned to Technical User in SU01 to allow the SAP data connector to connect to your SAP system.

  • NPLK900202After importing this TR you will get role - /MSFTSEN/SENTINEL_AGENT_BASIC which needs to be assigned to Technical User in SU01 to allow the SAP data connector to connect to your SAP system. (This role has the minimal required permissions for the data connector to operate)

  • Go to transaction STMS_IMPORT transaction and import the mentioned TR's.
