Microsoft 365 Fundamentals MS-900 Practice Question

Access requests are continually authenticated and authorized, with no implicit trust granted - The Zero Trust model operates on the principle of "never trust, always verify," requiring ongoing authentication and authorization for each access request, regardless of where the request originates. This approach prevents implicit trust, ensuring security even if a device is inside the corporate network.

Users and devices are authenticated and authorized once when they first access the network - In Zero Trust, authentication and authorization are not one-time events. Continuous verification of users and devices is central to this model to prevent unauthorized access throughout each session.

Network traffic inside the corporate firewall is assumed to be trustworthy - This describes a traditional security approach, not Zero Trust. In the Zero Trust model, no network traffic is automatically trusted, whether inside or outside the corporate firewall. Every access request is evaluated.

Security is enforced at the network perimeter through firewalls and VPNs - While traditional security models often focus on perimeter defenses, Zero Trust emphasizes security at every layer, focusing on identity, device health, and data protection instead of relying solely on perimeter-based security.
