What does the term "Zero Trust" imply in the context of Azure security?

The term "Zero Trust" in the context of Azure security fundamentally revolves around the principle of "Assume breach." This means that no entity, whether inside or outside the organization’s network, is trusted by default. Every request for access to resources must be verified as if it originates from an untrusted network. This approach emphasizes rigorous identity verification, strong authentication methods, and the principle of least privilege, ensuring that users and devices are authenticated and only granted access to the resources necessary for their roles.

This concept contrasts significantly with traditional security models, which often assume that users within the network perimeter can be trusted. By enforcing verification for every access request, Zero Trust helps to mitigate the risks associated with compromised credentials, insider threats, and potential breaches. It encourages continuous monitoring and validation of user identities and access permissions, thus enhancing the overall security posture of an organization operating in Azure or any other cloud environment.

The other concepts, while related to security practices, do not encapsulate the full scope of what Zero Trust entails and are more aligned with traditional security models or specific access controls.
