What is Zero Trust Architecture (ZTA)?

Zero Trust Architecture (ZTA) is a cybersecurity approach that emphasizes strict identity verification and the principle of never trust, always verify when it comes to accessing resources, regardless of whether they are inside or outside of a network perimeter. In ZTA, no user or device is automatically trusted, even if they are inside the corporate network. Instead, access is continuously verified based on various factors such as user identity, device health, location, and other contextual information before granting access to applications or data.

ZTA operates on the assumption that threats can come from both inside and outside the network, so it focuses on securing individual assets, implementing strong access controls, using encryption, and continuously monitoring and authenticating users and devices to ensure security. This model aims to improve overall cybersecurity posture by reducing the potential attack surface and minimizing the impact of security breaches.
