Guide to Security Needs and Requirements

This guide provides systems engineers with practical approaches for developing security needs and requirements throughout a system's lifecycle. It aligns security concepts with INCOSE's existing needs and requirements frameworks, offering guidance on:

• Conducting loss-driven security analysis
• Defining well-formed security needs and requirements
• Transforming security needs into design requirements
• Verifying and validating security aspects
• Ensuring sustainable security post-deployment

The guide maps security terminology to standard systems engineering processes, enabling better integration of security considerations from concept to operation. It is an essential resource for systems engineers seeking to build security into complex systems from the ground up.
