An incident in Microsoft Defender XDR is a collection of correlated alerts and associated data that make up the story of an attack. Microsoft 365 services and apps create alerts when they detect a suspicious or malicious event or activity. Individual alerts provide valuable clues about a completed or ongoing attack. Attacks typically employ various techniques against different types of entities, such as devices, users, and mailboxes. The result of this is multiple alerts for multiple entities in your tenant. Piecing the individual alerts together to gain insight into an attack can be challenging and time-consuming, Microsoft Defender XDR automatically aggregates the alerts and their associated information into an incident. A typical Incident Response workflow in Microsoft Defender XDR begins with a triage action, next is the investigate action, and finally is the response action. Microsoft 365 Defender Incident Response responds to unsecure credential attacks due to Incident Response monitoring for newly executed processes, suspicious file access activity, and application logs for activity that may highlight malicious attempts to access application data.
