Course Outline

Introduction and Course Orientation

  • Course objectives, expected outcomes, and lab environment setup.
  • Overview of EDR architecture and OpenEDR components.
  • Review of the MITRE ATT&CK framework and core threat-hunting principles.

OpenEDR Deployment and Telemetry Collection

  • Installing and configuring OpenEDR agents on Windows endpoints.
  • Details on server components, data ingestion pipelines, and storage considerations.
  • Configuring telemetry sources, event normalization, and enrichment processes.

Understanding Endpoint Telemetry and Event Modeling

  • Key endpoint event types, fields, and their mapping to ATT&CK techniques.
  • Strategies for event filtering, correlation, and noise reduction.
  • Developing reliable detection signals from low-fidelity telemetry.

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 profiles and telemetry availability.

Threat Hunting Methodologies

  • Comparing hypothesis-driven hunting with indicator-led investigations.
  • Developing hunt playbooks and iterative discovery workflows.
  • Hands-on hunting labs focusing on identifying lateral movement, persistence, and privilege escalation patterns.

Detection Engineering and Tuning

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

Incident Response and Root Cause Analysis with OpenEDR

  • Leveraging OpenEDR to triage alerts, investigate incidents, and timeline attacks.
  • Collecting forensic artifacts, preserving evidence, and managing chain-of-custody.
  • Integrating findings into IR playbooks and remediation workflows.

Automation, Orchestration, and Integration

  • Automating routine hunts and alert enrichment using scripts and connectors.
  • Integrating OpenEDR with SIEM, SOAR, and threat intelligence platforms.
  • Scaling telemetry, retention, and operational aspects for enterprise deployments.

Advanced Use Cases and Red Team Collaboration

  • Simulating adversary behavior for validation through purple-team exercises and ATT&CK-based emulation.
  • Case studies covering real-world hunts and post-incident analyses.
  • Designing continuous improvement cycles for detection coverage.

Capstone Lab and Presentations

  • Guided capstone project: executing a full hunt from hypothesis through containment and root cause analysis using lab scenarios.
  • Participant presentations of findings and recommended mitigations.
  • Course wrap-up, materials distribution, and recommended next steps.

Requirements

  • A solid understanding of endpoint security fundamentals.
  • Practical experience with log analysis and basic Linux/Windows administration.
  • Familiarity with common attack techniques and incident response concepts.

Target Audience

  • Security Operations Center (SOC) analysts.
  • Threat hunters and incident responders.
  • Security engineers responsible for detection engineering and telemetry.
