This eBook, titled Zero Trust Campus: Securing the Modern Campus in a Digital Era, serves as a strategic guide for higher education leaders to modernize their IT infrastructure using Zero Trust Architecture. It explores how traditional "castle-and-moat" security models are no longer sufficient for today’s distributed research and learning environments, which are increasingly targeted by sophisticated cyberattacks. The document provides a comprehensive roadmap for implementation, addressing technical deployment, cultural integration, and the specific use cases unique to academic institutions.
