Describe Zero Trust model

Zero Trust is a security model that assumes the worst case scenario and protects resources with that expectation. Zero Trust assumes breach at the outset, and then verifies each request as though it originated from an uncontrolled network.

Today, organizations need a new security model that effectively adapts to the complexity of the modern environment; embraces the mobile workforce; and protects people, devices, applications, and data wherever they’re located.

To address this new world of computing, Microsoft highly recommends the Zero Trust security model, which is based on these guiding principles:

• Verify explicitly – Always authenticate and authorize based on all available data points.
• Use least privilege access – Limit user access with Just-In-Time and Just-Enough-Access (JIT/JEA), risk-based adaptive policies, and data protection.
• Assume breach – Minimize blast radius and segment access. Verify end-to-end encryption. Use analytics to get visibility, drive threat detection, and improve defenses.
