The security design paradigm that requires all requests to be authenticated before they can continue is known as Zero Trust Security.
In a Zero Trust model, no entity—whether inside or outside the organization—is inherently trusted. Every request for access must be authenticated and authorized, regardless of its origin. This approach emphasizes the principle of "never trust, always verify," ensuring that all network traffic is continuously validated, and access to resources is granted based only on strict identity verification processes.
As organizations transition to public cloud platforms, implementing a Zero Trust Architecture helps to minimize security risks by requiring robust authentication for every access request, thereby protecting sensitive data and systems from unauthorized access.
