- Design secure architectures: IAM, encryption, least privilege.
- Design resilient architectures: HA, DR, fault tolerance.
- Design high-performing architectures: caching, scaling, right service choice.
- Design cost-optimized architectures: storage classes, pricing tradeoffs.

Frequently Asked Questions
Is GCIH mostly theory?
No. It’s very practical: detection signals, investigation flow, and response decisions.
How do I avoid traps?
Start with the IR phase and objective (contain vs eradicate vs recover), then choose the action that fits.
Do I need deep reverse engineering?
No. You need practical understanding of attacker behavior and how to detect/respond.
