Threat Detection, Investigation, and Response
Threat Detection • Endpoint Investigation • Alert Triage • Incident Response • Microsoft Security Operations
Microsoft Defender XDR is an extended detection and response platform that helps security teams detect, investigate, and respond to threats across endpoints, identities, email, cloud apps, and Microsoft 365.
As a Security Analyst, I use Defender XDR to review incidents, analyze alerts, inspect affected devices and users, investigate timelines, and support containment and remediation activities.
My hands-on experience includes alert triage, endpoint investigation, advanced hunting, incident correlation, evidence review, and response coordination with Microsoft Sentinel and Microsoft Entra ID.
Threat Detection, Investigation, and Response
This project demonstrates my practical experience working with Microsoft Defender XDR in a security operations workflow. The objective was to detect suspicious activity, investigate alerts, validate incidents, and support fast response.
I reviewed incident severity, affected assets, alert evidence, device timelines, identity signals, and related security events to understand the full scope of each case.
The project also included advanced hunting queries, endpoint evidence review, and correlation with Microsoft Sentinel to improve investigation quality and response decisions.
