Zero Trust
A security model built on "never trust, always verify" — no request is trusted by default just because it came from inside the network perimeter; every access decision is checked on its own merits.
aka: ZTNA
Zero Trust replaces the old model of a hardened perimeter with a soft, trusted interior — the assumption that already broke down once attackers learned to get one foothold and move laterally. Identity becomes the real control plane: every request carries its own continuously re-evaluated trust, not a network location’s borrowed trust, and ABAC’s attribute-driven policies are the engine most Zero Trust decisions actually run on.
