Zero Trust - Modern Security Architecture Principle
Zero Trust is a security paradigm based on the principle of "never trust, always verify": No user, device, or network segment is implicitly trusted—every access request is explicitly verified.
Summary: Zero Trust replaces the outdated perimeter model (“trusted inside, untrusted outside”) with continuous verification: identity (who?), device (health status?), context (location, time, behavior). Core principles: Verify Explicitly, Least Privilege Access, Assume Breach. NIST SP 800-207, Microsoft Zero Trust, Google BeyondCorp. Technical components: Identity Provider (Azure AD/Okta), MDM/EDR for Device Trust, Microsegmentation, CASB, SASE.
