Security Engineering: Building Defensible Systems
Security Engineering: Building Defensible Systems Defensible systems are built with the assumption that threats exist and mistakes will happen. The goal is to limit damage, detect problems early, and recover quickly. Start with business needs, not only tech, and design for failure as a default. Foundations of Defensible Design Secure by default: services run with minimal privileges and sensible defaults. Defense in depth: multiple, independent layers protect data and behavior. Threat modeling: identify likely attackers and weak links early. Resilience: systems tolerate faults and recover fast. Observability: strong logging, metrics, and alerts help you detect trouble. In practice, these ideas become concrete. Architecture reviews, regular threat modeling, and automated checks in CI/CD help lock in secure design before deployment. ...
