What is zero trust architecture, and how does it enhance cybersecurity?

Zero trust architecture is a security model that assumes threats could be both external and internal and does not trust any user or device by default, even if they are inside the network perimeter. It requires verification of every user and device attempting to access resources on the network, regardless of their location. This approach helps improve cybersecurity resilience by reducing the attack surface, enforcing strict access controls, continuously monitoring and analyzing network activity for anomalies, and adopting a least-privileged access approach. Zero trust architecture enhances security posture by providing better visibility and control over network traffic, mitigating the risk of lateral movement by attackers, and ensuring that resources are only accessed by authorized entities.
