The Zero Trust model is a security strategy that assumes that any user, device, or network inside or outside of an organization’s perimeter can be compromised. Instead of relying on the traditional security model of a “perimeter” or “castle and moat,” where security is focused on keeping unauthorized users out, the Zero Trust model assumes that there are no “inside” or “outside” users, and that all access to resources must be verified and authenticated.
The Zero Trust model involves implementing a number of security controls and technologies, such as multi-factor authentication, network segmentation, and continuous monitoring, to verify the identity and trustworthiness of users and devices before granting access to resources.
It also involves implementing security controls at all layers of the infrastructure, such as endpoint security, network security, and cloud security, to protect against malicious actors who have already breached the perimeter.
The goal of Zero Trust is to move away from a perimeter-based security model, where trust is based on an IP address, and towards a model where trust is based on user identity and device security. This allows organizations to better protect their resources and data from malicious actors, regardless of their location.
