Zero trust architecture focuses on enhancing cybersecurity by operating under the principle that no user or device, whether inside or outside the network, should be trusted by default. This approach requires strict verification for every person and device trying to access resources, regardless of their location. By implementing zero trust principles, organizations can reduce the risk of data breaches and unauthorized access. This model involves continuous monitoring and validation of users and devices, enforcing least privilege access, and incorporating advanced security measures such as multi-factor authentication.
