The Zero Trust network security model is based on the security principle of "Least Privilege".

Here's a step-by-step explanation:

1. The Zero Trust model is a security concept centered on the belief that organizations should not automatically trust anything inside or outside its perimeters and instead must verify anything and everything trying to connect to its systems before granting access.

2. The principle of "Least Privilege" means giving a user account or process only those privileges which are essential to perform its intended function. For example, a user account for a person who only needs to read certain documents does not need to have write access to those documents, or to any other part of the system.

3. Therefore, in a Zero Trust model, every access request is strongly authenticated, strictly authorized under the principle of least privilege and is inspected and logged.

4. This means that the Zero Trust model operates on the assumption that threats can come from anywhere—inside or outside the network—and that every user, device, and network flow must be authenticated and authorized.

5. Hence, the Zero Trust model is based on the principle of "Least Privilege".
