This course covers the XDR workflow, including configuring data sources through extended detection via Trellix Helix, Trellix Network Security, and Trellix Endpoint Security (HX). Learners triage Trellix-generated alerts, derive actionable information from those alerts, and inspect affected endpoints using live analysis and investigation fundamentals.

Hands-on activities include writing TQL searches, creating rules, analyzing and validating alerts from Helix, Network Security, and Endpoint Security (HX), deep analysis of endpoint data collections, and response actions through Endpoint Security (HX) such as collecting data from across the enterprise and containing endpoints.

• Identify the components needed to deploy Trellix Helix, Network Security, and Endpoint Security (HX)
• Determine which data sources are most useful for Helix detection and investigation
• Locate and use critical information in a Helix alert to assess a potential threat
• Comfortably pivot from the Helix web console to native Trellix tools for deep analysis
• Validate Network Security and Endpoint Security (HX) alerts
• Use specialized features of Network Security and Endpoint Security (HX) to investigate and respond to potential threats across enterprise systems and endpoints
