Security & Resilience

Security is not a feature you bolt on — it is an architectural property that must be designed into every layer of your system from the start. This path challenges you to design four security and resilience architectures that address the threats and failure modes real engineering teams face: zero-trust network design that eliminates implicit trust, cascading failure prevention that contains blast radius, secrets management that eliminates hardcoded credentials, and compliance automation that proves governance at audit time. Each challenge requires you to think like both an attacker and a defender, designing defense-in-depth architectures where multiple layers of protection ensure that no single vulnerability compromises the entire system.
