Zero Trust Overview & Tenets
Traditional network security often assumes that users and devices inside the corporate network are trusted. Zero trust changes that assumption.
Under zero trust, both users and devices are evaluated continuously based on identity, context, and policy. The network itself is not treated as a trusted boundary.
Core Concept
- Inside network is not automatically trusted
- Outside network is not automatically untrusted
- Trust must be explicitly verified for every access request
- Access is granted based on least privilege and contextual signals
Comparison
| Model | Trust Assumption |
|---|---|
| Traditional Network Security | Corporate network = trusted |
| Zero Trust | Corporate network = untrusted |
Key Outcome
Zero trust moves security from a network-centric model to an identity-centric, policy-driven model.
