Zero Trust Architecture (Overview)

Summary

A security model assuming no user or system should be trusted by default, even inside the network perimeter — every request is verified regardless of where it originates, replacing the older 'trusted internal network' assumption.

• 1Learn the core zero trust principle: 'never trust, always verify'.
• 2Compare zero trust to the traditional perimeter-based security model it's replacing.
• 3Understand why zero trust has become more relevant as remote work and cloud infrastructure blur network boundaries.
