Zero Trust: Application and Data Security

This course applies Zero Trust principles specifically to the application layer and to the data an organization is trying to protect. Where a broader Zero Trust architecture course covers identity, network segmentation, and overall policy, this material drills into how applications are secured from the inside out, how data is protected at rest, in transit, and in use, and how an organization operationalizes Zero Trust as a strategic program rather than a single product.

Containerization is particularly valuable in a Zero Trust environment because it encapsulates application components into isolated units. If an attacker compromises one container, the isolation boundary makes it significantly harder for them to pivot into other parts of the system, reducing the blast radius of any single breach.

Within a Zero Trust model, no default trust is granted based on network location or prior access — every access attempt to an application must be verified.
