The protect surface is the Zero Trust focus on the critical data, applications, assets, and services an organization must defend, not the attack surface.
Protect Surface Definition: The protect surface is the Zero Trust focus on the critical data, applications, assets, and services an organization must defend, not the attack surface.
In Zero Trust architecture, the protect surface is the concept introduced by John Kindervag that shifts focus away from the constantly expanding attack surface toward the specific data, applications, assets, and services that an organization must defend. Often summarized by the acronym DAAS, the protect surface is far smaller and more clearly defined than the attack surface, making it possible to place granular controls and microperimeters close to what truly matters. Identifying the protect surface is the first step in designing a Zero Trust network.
