Which principle is NOT part of the Zero Trust framework?

• A. Define the perimeter by physical locations
• B. Use identity as the primary security boundary
• C. Always verify the permissions of a user explicitly
• D. Always assume that the user system can be breached

Answer: (A)

The principle of defining the perimeter by physical locations does not align with the Zero Trust framework. Zero Trust is built on the premise that traditional network security, which relies on a defined perimeter (such as a corporate firewall), is inadequate for protecting modern digital environments. Instead, Zero Trust emphasizes that security should not depend on any physical boundaries, as the most significant threats often come from inside the network or from trusted users. In contrast, the Zero Trust framework focuses on continuously verifying the identity and security posture of users and devices, regardless of their physical location within or outside the network. This approach recognizes that threats can exist at any layer and advocates for a "never trust, always verify" mentality. By using identity as the primary security boundary, continuously verifying permissions, and assuming that users’ systems can be compromised, Zero Trust ensures that every access request is thoroughly validated.
