The Secure by Design approach aims to tackle the challenges of developing and scaling secure applications. This involves considering potential security risks earlier in the development cycle, adopting a defense-in-depth strategy, and implementing multiple layers of security throughout the development process. To achieve this, organizations can follow principles such as a decentralized model for workstreams, a scalable system for sharing knowledge, and a customer-centric design for software. By doing so, teams can significantly reduce both the costs of fixing vulnerabilities and the risk of introducing them to customers. The benefits of adopting Secure by Design principles include cultivating a DevSecOps culture, improving overall developer experience and productivity, and proactively discovering and mitigating critical vulnerabilities in applications and services.
