What is the concept of Zero Trust Architecture (ZTA) and how does it differ from traditional perimeter-based security?

Accepted Answer

Zero Trust Architecture (ZTA) operates on the principle of 'never trust, always verify,' ensuring no user, device, or network segment is trusted by default. This differs from traditional perimeter-based security, which assumes everything inside the network boundary is trusted.
