What Does "Never Trust" Mean?
"Never Trust" is a fundamental principle of Zero Trust architecture that means no user, device, or application should be trusted by default, regardless of their location in the network.
In traditional perimeter-based security models, devices and users inside the network were considered trusted. The "Never Trust" principle rejects this assumption, requiring continuous verification of every access request, even if it originates from inside the network.
This approach is especially important in modern cloud environments where network boundaries are blurred, and threats can come from both outside and inside the organization. The "Never Trust" principle provides protection against account compromise, malware, and insider threats.
Key Aspects:

Principle Implementation
Multi-Factor Authentication
Requiring multiple authentication factors for every access request, including passwords, tokens, biometrics, and contextual data.
Device Verification
Verifying device state, security policy compliance, and absence of compromise before granting access.
Network Segmentation
Dividing the network into isolated segments with access control between them, even within the perimeter.
Continuous Monitoring
Continuous tracking of user and device activity to detect anomalies and potential threats.
