Zero Trust Architecture is a cybersecurity model that operates on the principle of "never trust, always verify." It assumes that threats can exist both inside and outside an organization's network. Therefore, every user and device must be authenticated and authorized before accessing any resources, regardless of their location. This approach emphasizes continuous monitoring and strict access controls. By segmenting networks and applying the least privilege principle, organizations can minimize potential damage from breaches. Zero Trust helps protect sensitive data and systems by ensuring that only verified users and devices can access critical resources.
