What best practice enhances security in a hybrid cloud setup?

Establishing a zero-trust security model significantly enhances security in a hybrid cloud environment by fundamentally changing the approach to network security. The zero-trust model operates on the principle of "never trust, always verify." This means that no user, device, or application is trusted by default, whether they are inside or outside the network perimeter.

In a hybrid cloud setup, where resources span both on-premises and cloud environments, implementing a zero-trust framework helps ensure that access controls are strict and continuously evaluated. This model emphasizes the need for strict identity verification and restricts access based on the least privilege principle, meaning users and services can only access the resources necessary for their role.

This approach also supports stronger authentication mechanisms, micro-segmentation, and continuous monitoring and logging of activities, all of which are crucial in mitigating risks associated with multiple environments and varying security postures. By reducing the attack surface and ensuring that any access request is meticulously scrutinized, a zero-trust model greatly enhances the overall security of a hybrid cloud infrastructure.
