Building security from the ground up means integrating security measures into the core architecture from the start, rather than adding it later. It involves understanding and applying existing modular security mechanisms rather than relying solely on bespoke solutions. Effective security design is essential due to the inherent risks of technology, and education around these risks motivates innovation. However, the practical application often relies on established best practices and frameworks, highlighting that while security is a unique consideration, it should be part of a broader engineering strategy.
