Exam SC-200 topic 6 question 4 discussion

D for me

Rule Settings: If the rules (Rule1, Rule2, Rule3, Rule4) are independent of each other (i.e., they don't have the same incident grouping criteria), each rule will create its own incident. However, if the incident grouping feature is enabled and the rules have matching criteria (e.g., same user or same event), they could be grouped into a single incident. Incident Grouping: Incident grouping is a feature that groups alerts from different detection rules into a single incident based on specific matching criteria like the same entity (e.g., user, IP address, or device). If the rules match the same underlying entity (for example, User1), the system might group those alerts into one incident. Without grouping, each rule will generate a separate incident. There is nothing about grouping mentioned, so D

The answer is A. 1. Here's why: Incident Grouping: Microsoft Sentinel has a built-in mechanism to group related alerts into a single incident. This helps reduce alert fatigue and provides a more comprehensive view of security events.

1 analytics rule generates alerts based on the KQL query you use, these alerts are grouped together or not , according to you configuration choice and these alerts can be turned into incidents if you so choose. You can group the incidents into one single incidents too based on multiple factors like, say: all common entities, or one common entity or again, group them all together no matter what the entities are. This is all configurable on a per Analytics Rule basis. So One Analytics Rule generates one incident or alert or multiple incidents or alerts . Here You have four Analytics rules that detect different things where all the conditions for each rules match a particular event. So 1 incident at least per rule would be created following that logic, therefore 4 incidents.

I go with A, Microsoft Defender groups alerts in Incident when the same user generated this alerts.

https://learn.microsoft.com/en-us/defender-xdr/alerts-incidents-correlation\ - A for me Incident correlation and merging Microsoft Defender XDR's correlation activities don't stop when incidents are created. Defender XDR continues to detect commonalities and relationships between incidents, and between alerts across incidents. When two or more incidents are determined to be sufficiently alike, Defender XDR merges the incidents into a single incident. How does Defender XDR make that determination? Defender XDR's correlation engine merges incidents when it recognizes common elements between alerts in separate incidents, based on its deep knowledge of the data and the attack behavior. Some of these elements include: Entities—assets like users, devices, mailboxes, and others Artifacts—files, processes, email senders, and others Time frames Sequences of events that point to multistage attacks—for example, a malicious email click event that follows closely on a phishing email detection.

Even though all 4 rules were triggered, they were triggered by a single user. Defender will then group all alerts and incidents under the single user
