Secure by design

Common card · No. 472527

Secure by design (SbD) is a cyber security and systems engineering concept that mandates that security be incorporated into systems from the outset rather than as an afterthought. Instead of being retrofitted later through patching or external controls, it focuses on integrating security requirements into the architecture itself by incorporating protections at the very beginning of the design process for hardware, software, and services. Assuming that systems will be attacked, secure by design entails limiting their architecture to make compromises challenging, contained, and recoverable. It highlights strategies like defence in depth, minimising attack surfaces, the principle of least privilege principle, and integrating detection and response mechanisms. SbD treats security as a design constraint on par with performance, usability, and cost, in contrast to reactive approaches that mainly rely on vulnerability management after deployment. Since significant cyber events, such as supply...
