Proactive Threat Hunting

• Execute hypothesis-driven hunts based on adversary TTPs and threat intelligence.
• Analyze telemetry from SIEM, EDR/XDR, NDR, and cloud-native platforms to identify anomalies.
• Develop and maintain hunting queries and scripts for automation and repeatability.
• Validate detection coverage through purple team exercises and adversary emulation.

Threat Intelligence Integration

• Incorporate emerging threat intelligence into hunting hypotheses and detection pipelines.
• Maintain awareness of global threat actor tactics, techniques, and procedures (MITRE ATT&CK).

Continuous Improvement

• Document hunt findings and feed insights into detection engineering and SOC workflows.
