Domain overview
This domain covers responding to security incidents using Microsoft Sentinel, Defender XDR, and related tools. It tests your ability to triage, investigate, contain, and remediate threats. You must know how to use incident management, automation rules, playbooks, and advanced hunting to resolve attacks like phishing, ransomware, and data exfiltration.
Exam objectives
Manage incidents in Microsoft 365 Defender and Microsoft Sentinel, including assignment, status, and classification.
Use advanced hunting with KQL to investigate incidents and identify affected entities.
Configure automation rules and playbooks to automate response actions like isolating devices or blocking users.
Perform remediation actions such as soft-deleting malicious emails, isolating endpoints, or revoking user sessions.
Confusing automation rules with playbooks: automation rules trigger playbooks but do not perform actions directly; playbooks contain the logic.
Forgetting that Microsoft Sentinel incidents can include entities from multiple sources, requiring cross-workspace investigation.
Assuming Defender for Office 365 automatically blocks all phishing emails; manual remediation may be needed for missed threats.

The incident includes an alert from Microsoft Defender for Identity indicating a possible brute-force attack. The user's account is a privileged administrator. Your organization has strict compliance requirements: any privileged account compromise must be contained within 15 minutes of detection. You have the following tools available: Microsoft Entra ID with Privileged Identity Management (PIM), Microsoft Defender for Cloud Apps, and Microsoft 365 Defender automation rules. The incident is now 5 minutes old. What should you do to meet the compliance requirement?
