Modern defensible architecture

Modern defensible architecture (MDA) is a framework for applying secure design and security architecture in a layered approach to improve an organisation’s cyber security resilience against evolving cyber threats. It brings together layered architecture, zero trust principles and secure- by- design practices to help organisations build stronger and more resilient environments. This collection of publications helps organisations understand MDA concepts, align technology decisions with business and security objectives, and develop practical implementation and investment roadmaps. The publications support senior leaders, architects and security practitioners who are planning, building or enhancing cyber security capabilities. Adopting MDA can help organisations improve resilience, maintain secure business operations and strengthen assurance that security requirements are met.
