"Secure by Design" (SbD), not to be confused with System Based Design (SBD) is a development method and approach as well as a proactive cybersecurity strategy that integrates security into the development lifecycle of software and hardware products from the outset. This approach ensures that security measures are embedded at the earliest stages of development, creating a robust foundation for secure operations. SbD can be considered both an approach and a method within systems engineering: As an Approach : SbD represents a strategic orientation towards designing systems. It involves a mindset or philosophy that prioritises security from the initial stages of system development. As an approach, it shapes the overall framework and philosophy guiding a project, influencing decision-making at each step to prioritise security. As a Method : SbD encompasses specific methods, including practical techniques and processes, that are impleme
