GCIA — GIAC Certified Intrusion Analyst
GIAC's intrusion analysis certification covering deep packet inspection, protocol analysis, network forensics, and IDS/IPS tuning. DoD 8140 approved and consistently in demand for network security analyst and SOC roles. One of the more technically rigorous GIAC certs despite the MCQ format — network analysis genuinely requires pattern recognition and protocol knowledge that can't be fully memorized. Pairs naturally with GCIH for a comprehensive SOC analyst credential. Among the most respected GIAC credentials in the network security domain.
