sicherheitsbydesign

SicherheitsbyDesign is a design philosophy that seeks to incorporate security considerations into the design and development of systems, products, and processes from the outset. The goal is to prevent security weaknesses rather than fix them after deployment.

Origin and scope: The concept is closely related to English-language security by design and is applied across software, hardware, embedded devices, networks, and organizational practices. It is often implemented as part of a secure development lifecycle and risk management framework.

Core principles include secure by default, least privilege, defense in depth, threat modeling, secure coding practices, and continual verification. It emphasizes requirements engineering with explicit security requirements, architecture and design reviews, and the use of verifiable and auditable controls.

Implementation practices include secure design patterns, secure coding standards, regular security testing (static and dynamic analysis, fuzzing), software bill of materials, supply chain protection, and a robust update and vulnerability management process. It also covers incident response planning and maintainability to ensure long-term security.

Impact and challenges: When adopted early, SicherheitsbyDesign can reduce the cost and impact of security incidents, improve user trust, and help meet regulatory or contractual security requirements. Challenges include higher upfront costs, need for cross-disciplinary collaboration, complexity of modern systems, and keeping up with evolving threats.
