What is Zero Trust Architecture in Network Security?
Zero Trust Architecture in Network Security is a security model that requires strict identity verification for every person and device attempting to access resources on a network, regardless of whether they are inside or outside the network perimeter. This approach is based on the principle of “never trust, always verify,” which means that no user or device is trusted by default, and access is granted only after verifying the user’s identity and the security posture of the device. The effectiveness of Zero Trust Architecture is supported by the increasing frequency of data breaches and cyberattacks, which have shown that traditional perimeter-based security measures are insufficient. According to a 2021 report by Cybersecurity Insiders, 76% of organizations are actively considering or implementing Zero Trust strategies to enhance their security posture.
How does Zero Trust Architecture differ from traditional security models?
Zero Trust Architecture (ZTA) fundamentally differs from traditional security models by adopting a “never trust, always verify” approach, which assumes that threats can exist both inside and outside the network perimeter.
