Understanding Zero Trust Architecture

By Kerrick Rosemond Jr.

 Zero trust architecture (ZTA) operates by continuously verifying the identity and integrity of devices, users, and applications. It employs strict access controls alongside real-time monitoring and dynamic policy enforcement.

With a ZTA approach, system administrators no longer automatically trust any user or device attempting to access our networks. Instead, every request is verified and authenticated, regardless of whether it originates from inside or outside the network perimeter. This concept emphasizes moving from an assumption of trust by default to a continuous verification process, ensuring that only authorized users and devices are granted access.

Texas RE encourages Responsible Entities to review the National Institute of Standards and Technology (NIST) SP 800-207 for more information and an in-depth understanding of deployment models and use cases within zero trust.
