List of Questions and Answers for a Job Interview for Zero Trust Architect

Here are some zero trust architect job interview questions and answers to help you prepare:

Question 1

Explain the core principles of zero trust architecture.
Answer:
Zero trust is based on the principle of "never trust, always verify." It assumes that no user or device, whether inside or outside the network perimeter, is inherently trustworthy.

Authentication and authorization are required for every access request. Microsegmentation, least privilege access, and continuous monitoring are also key elements.

Question 2

How does zero trust differ from traditional network security models?
Answer:
Traditional models rely on perimeter-based security, assuming everything inside the network is safe. This approach is vulnerable to insider threats and lateral movement by attackers.

Zero trust eliminates the concept of an implicit trust zone. It verifies every user and device, regardless of their location, before granting access.
