What does Zero Trust imply about internal network behavior?

Zero Trust fundamentally asserts that trust should not be automatically granted based on network location or access level, which includes internal network behavior. Therefore, under the Zero Trust model, actions taken within an internal network must still undergo verification and scrutiny, much like those coming from external sources. This means that no user or device—regardless of whether they are inside or outside the organization—should be treated as inherently trustworthy. By validating internal actions, organizations can better defend against both external and internal threats, ensuring that security controls are consistently applied throughout the network.

The emphasis on verifying internal actions serves as a crucial component of an effective cybersecurity strategy, reinforcing the idea that security is a continuous process rather than a one-time assessment.
