Tools / Zero Trust Architecture (ZTA) Interview questions

What is the difference between implicit trust zones and explicit trust zones?

An implicit trust zone is a traditional network segment, such as an internal LAN, where anything inside is trusted without per-request verification simply because of where it sits on the network. Once a device is in that zone, it typically enjoys broad reach with little additional scrutiny.

An explicit trust zone requires every request, regardless of whether it originates internally or externally, to undergo policy evaluation before access is granted. Nothing is trusted purely by virtue of location.

Zero Trust's practical goal is to shrink implicit trust zones as close as feasible to a single resource, ideally eliminating them entirely, so that "being on the network" no longer confers any privilege on its own.

An implicit trust zone grants access primarily based on:
Zero Trust's goal regarding implicit trust zones is to:
