The traditional security model — "trust everything inside the network perimeter" — doesn't work in cloud. There is no perimeter. Resources span multiple accounts, regions, and connectivity paths. Developers deploy from home networks. APIs are called from everywhere.
Zero Trust flips the model: never trust, always verify. Every request is authenticated, authorized, and encrypted — regardless of where it comes from. On AWS, this isn't a single product. It's an architecture pattern built from multiple services working together.
This post covers how to implement Zero Trust on AWS using the services available today, with practical patterns for user-to-application access, service-to-service communication, and data protection.
