Understanding Endpoint Telemetry & Event Modeling

  • Key endpoint event types, fields, and their correlation with ATT&CK techniques
  • Event filtering, correlation strategies, and methods for noise reduction
  • Generating reliable detection signals from low-fidelity telemetry data

Mapping Detections to MITRE ATT&CK

  • Translating telemetry into ATT&CK technique coverage and identifying detection gaps
  • Utilizing ATT&CK Navigator and documenting mapping decisions
  • Prioritizing techniques for hunting based on risk levels and telemetry availability

Threat Hunting Methodologies

  • Hypothesis-driven hunting versus indicator-led investigations
  • Developing hunt playbooks and iterative discovery workflows
  • Hands-on labs: Identifying patterns of lateral movement, persistence, and privilege escalation

Detection Engineering & Tuning

  • Designing detection rules using event correlation and behavioral baselines
  • Testing rules, tuning to minimize false positives, and evaluating effectiveness
  • Creating reusable signatures and analytic content across the environment

Incident Response & Root Cause Analysis with OpenEDR

  • Leveraging OpenEDR for alert triage, incident investigation, and attack timeline reconstruction
  • Forensic artifact collection, evidence preservation, and chain-of-custody protocols
  • Integrating investigation findings into IR playbooks and remediation processes

Automation, Orchestration & Integration
