A Security Model for Distributed Critical Systems

This white paper presents a security architecture model for critical, distributed systems.

This model is a valuable tool to:

Simplify analysis of complex systems.
Assess existing systems by pinpointing potential security issues.
Design new systems by integrating lessons learned from past experience.

The model draws upon Zero Trust and ISO62443 security principles and is designed to assist functional and security architects in designing and analysing complex distributed systems.
