Enterprise SIEM Monitoring & Incident Investigation
Enterprise SIEM Monitoring • Incident Investigation • Threat Hunting • KQL Query Development • Microsoft Defender XDR Integration
Microsoft Sentinel is Microsoft's cloud-native Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platform. It enables organizations to collect, analyze, detect, investigate, and respond to security threats across on-premises, cloud, and hybrid environments.
As a Security Analyst, I use Microsoft Sentinel to monitor enterprise security events, investigate incidents, perform threat hunting using Kusto Query Language (KQL), analyze logs from multiple data sources, and support incident response activities.
My hands-on experience includes creating analytics rules, investigating security alerts, correlating events, performing log analysis, integrating Microsoft Defender XDR and Azure services, and supporting incident response activities.
Enterprise SIEM Monitoring & Incident Investigation
This project demonstrates my practical experience working with Microsoft Sentinel in a Security Operations Center (SOC) environment. The objective was to monitor enterprise security events, investigate incidents, perform threat hunting, and improve the organization's security posture using Microsoft's cloud-native SIEM platform.
Throughout this project, I analyzed security alerts generated from multiple data sources, validated incidents, correlated events, executed Kusto Query Language (KQL) queries, and collaborated with security teams to investigate and respond to suspicious activities.
The project also involved integrating Microsoft Defender XDR, Azure Monitor, and Log Analytics to provide centralized security monitoring and faster incident investigation.
By combining SIEM monitoring, threat intelligence, incident response, and proactive threat hunting, this project helped strengthen enterprise visibility and improve security operations.

Microsoft Sentinel incident investigation process followed during security operations
Monitored Microsoft Sentinel analytics rules, incidents, and security alerts generated from multiple enterprise data sources.
Investigated alerts using Microsoft Sentinel, Microsoft Defender XDR, Log Analytics and Kusto Query Language (KQL).
Correlated security events, identified suspicious activities and performed proactive threat hunting across enterprise environments.
Validated incidents, documented findings, collaborated with security teams, and supported remediation activities.
End-to-end Microsoft Sentinel incident lifecycle followed during Security Operations Center (SOC) monitoring.
Microsoft Sentinel Analytics Rules
Continuously monitored enterprise security alerts, analytics rules, incidents, and log data collected from Microsoft Defender XDR, Azure Monitor, Windows Security Events, and other connected enterprise data sources.
Microsoft Defender XDR
Investigated security alerts by analyzing incident timelines, correlating security events, validating malicious activities, and identifying attack patterns using Microsoft Defender XDR.
Kusto Query Language (KQL)
Executed KQL queries to analyze security logs, identify Indicators of Compromise (IOCs), investigate suspicious behaviour, and proactively hunt for advanced threats across the environment.
Security Operations Center (SOC)
Validated confirmed incidents, documented findings, collaborated with security teams, supported containment and remediation activities, and completed the incident response lifecycle.
Enterprise Security Operations
Improved analytics rules, reduced false positives, enhanced detection logic, documented lessons learned, and strengthened the organization's overall security posture through continuous monitoring and optimization.
