Explain the concept of a Zero Trust security model.

Begin by defining what Zero Trust is and emphasize that it is a security model that assumes no implicit trust is granted to assets or user accounts based solely on their physical or network location (i.e., local area networks versus the internet) or based on asset ownership (enterprise or personally owned). Explain the principle of "never trust, always verify," and how Zero Trust applies strict identity verification for every person and device trying to access resources on a private network, regardless of whether they are within or outside of the network perimeter. Highlight the importance of continuous verification and how Zero Trust minimizes the attack surface by enforcing least-privilege access.
