What does the term "zero trust" refer to in cloud security?

The term "zero trust" in cloud security refers to a security model that requires verification for every request, regardless of the source of that request, whether it originates inside or outside the network perimeter. This approach is based on the principle of "never trust, always verify," meaning that organizations should not automatically trust any user or device, even if they appear to be within the trusted network. Zero trust requires continuous authentication, strict identity verification, and monitoring of user actions to ensure that access to systems, services, and data is granted only to those who are rigorously identified and authenticated.

By implementing a zero trust architecture, organizations can minimize security risks and better protect sensitive data against threats such as insider attacks and compromised accounts. This model is especially relevant in cloud environments, where traditional perimeter-based defenses may be less effective due to the dynamic nature of cloud resources and the proliferation of remote access.

The other choices do not accurately capture the essence of the zero trust model. Storing data securely, encryption technology, and strategies for cost management in cloud services, while important in their own contexts, do not directly relate to the core principles of zero trust security frameworks.
