During January 2025, Biyxu developed foundational DefenderIncidentInvestigation capabilities within the Azure/Security-Copilot repository, focusing on device-centric security investigations and automated incident response for Microsoft Defender XDR. Biyxu implemented two YAML configurations, Device-Info.yml and Playbook-Device.yml, to define KQL-based queries and structured playbooks for device information gathering and incident response. This work established a reusable automation framework that enables standardized, repeatable workflows for device-level investigations, improving access to security data and supporting faster mean time to resolution. Leveraging skills in data querying, security analytics, and incident response, Biyxu’s contributions provided depth in automation and structured security operations engineering.
