securebyitself
Securebyitself is a design philosophy in information security that emphasizes embedding security into the core of a system so that its security properties arise from its architecture and code, rather than depend primarily on external controls or after-the-fact patches. The goal is resilience against threats by default.
Core principles include building with least privilege, secure defaults, defense in depth, robust input validation, memory
Implementation examples encompass secure-by-design software, container sandboxing, memory-safe languages, rigorous threat modeling, automated testing and fuzzing,
Applications span consumer software, embedded and IoT devices, industrial control systems, and cloud services. The approach
Limitations include potential performance costs, increased development complexity, and the risk of overreliance on internal protections.
