DIVE (Device Identity Verification & Enforcement) is a critical component of the Zero Trust Network Access (ZTNA) security model, specifically reinforcing the principle of 'Never Trust, Always Verify.' It extends security beyond user credentials by locking the user's connection profile to their device's unique identifier (UUID). This means that even if both the valid profile AND credentials are stolen, a hacker will not be able to connect from an unauthorized endpoint because the profile has been locked to a specific, authorized device. By requiring both a valid user identity and an authorized, device-locked profile, DIVE enforces the Principle of Least Privilege, drastically reducing the overall network attack surface.
