Microsoft Certified: Microsoft Cybersecurity Architect Expert (SC-100) Practice Test

The principle of "never trust, always verify" is fundamental to zero-trust architecture because it emphasizes a security model that operates under the assumption that threats could be both external and internal. Unlike traditional models that trust users and devices within the internal network, zero-trust requires continuous verification of identities, devices, and the security context for every access request.

This approach minimizes the risk of security breaches caused by compromised accounts or insider threats, as it ensures that every request, regardless of origin, is authenticated and authorized before access is granted to resources. Essentially, it implements a “least privilege” access model, where users and devices are given the minimum levels of access necessary to perform their functions while continually verifying their legitimacy.

This core principle helps organizations mitigate potential vulnerabilities and improve their overall security posture by ensuring that no one, whether inside or outside the organization, is automatically trusted.
