Microsoft Sentinel's Microsoft 365 Defender incident integration allows you to stream all Microsoft 365 Defender incidents into Microsoft Sentinel and keep them synchronized between both portals. To ensure proper functioning and performance of your security orchestration, automation, and response operations in your Microsoft Sentinel service, keep track of the health of your automation rules and playbooks by monitoring their execution logs. The foundation of Microsoft Sentinel is the data store; it combines high-performance querying, dynamic schema, and scales to massive data volumes. A regularly updated list of vulnerable products can be viewed in the Microsoft 365 Defender portal with matching recommendations. If you don't enable the connector, you may receive AADIP incidents without any data in them. Due to the broad network exploitation nature of vectors through which this vulnerability can be exploited and the fact that applying mitigations holistically across large environments will take time, we encourage defenders to look for signs of post-exploitation rather than fully relying on prevention. Once you have enabled the Microsoft 365 Defender data connector to collect incidents and alerts, Microsoft 365 Defender incidents will appear in the Microsoft Sentinel incidents queue, with Microsoft 365 Defender in the Product name field, shortly after they are generated in Microsoft 365 Defender.
