FAQs

Frequently Asked Questions

What is the GIAC Experienced Incident Handler (GX-IH) certification?

GX-IH validates advanced incident handling and investigation expertise. It tests hands-on knowledge across command-line forensic analysis, attack analysis, full incident investigations, infrastructure assessment, password attacks, network pivoting, protocol security, and web security analysis.

What are the GX-IH exam requirements?

The GX-IH exam consists of 82 questions, is web-based and proctored, has a 4-hour time limit, and requires a minimum passing score of 74%. Proctoring is available via ProctorU (remote) or PearsonVUE (onsite).

What topics does GX-IH cover?

GX-IH covers CLI-based forensic investigation, attack analysis and kill chain mapping, full incident lifecycle management, infrastructure security assessment, password attack investigation, network pivoting detection, protocol security, and web-based attack analysis from a responder perspective.

Who should take GX-IH?

GX-IH is designed for experienced incident responders, IR team leads, CIRT members, threat hunters, forensics leads, and senior security engineers who manage complex, multi-stage incident investigations across enterprise environments.

How does GX-IH differ from GCIH?

GCIH (GIAC Certified Incident Handler) is the practitioner-level IR certification. GX-IH is the advanced practitioner credential — testing deeper, multi-domain skills including command-line investigation, advanced attack analysis, and complex incident reconstruction across larger, more sophisticated attack scenarios.

Does GX-IH cover both offensive and defensive perspectives?

Yes — GX-IH approaches topics from both the attacker and defender perspective. Understanding how password attacks work, how pivoting is performed, and how web attacks are executed helps incident handlers more effectively recognise and investigate these techniques in the evidence they encounter.
