Security By Design
Security By Design is a software development methodology that integrates security considerations and practices into every phase of the software development lifecycle (SDLC), from initial design and architecture to deployment and maintenance. It emphasizes proactive threat modeling, secure coding standards, and continuous security testing to prevent vulnerabilities rather than fixing them after deployment. This approach aims to build inherently secure systems by making security a core requirement, not an afterthought.
Developers should adopt Security By Design when building applications that handle sensitive data (e.g., financial, healthcare, or personal information), operate in regulated industries (e.g., finance, government), or face high risks of cyberattacks (e.g., web services, IoT devices). It reduces long-term costs by minimizing security breaches, ensures compliance with standards like GDPR or HIPAA, and enhances user trust by preventing data leaks and exploits from the outset.
