Cyber Security Zero Trust
by Mark Hayward — UK Cyber Security Expert, Armed Forces Veteran, 144+ Books
The traditional 'castle and moat' approach to security is dead. Zero Trust Architecture rejects the assumption that anything inside the network perimeter can be trusted — instead requiring continuous verification for every user, device, and application, regardless of location. This book provides a practical, implementable guide to Zero Trust — covering identity-centric security, micro-segmentation, least-privilege access, continuous authentication, and how to transition from legacy perimeter models to Zero Trust in real-world enterprise environments.
What You'll Learn
- Zero Trust principles
- Identity-centric security
- Micro-segmentation
- Least-privilege access
- Continuous authentication
- Zero Trust for cloud environments
- Migration from perimeter security
