The zero trust security model is significant because it operates under the principle of "never trust, always verify." This approach requires strict identity verification for every user and device attempting to access resources, regardless of whether they're inside or outside the network perimeter. By minimizing trust assumptions, zero trust reduces the risk of cyberattacks and data breaches. It also emphasizes continuous monitoring and validation, enhancing overall security posture in organizations. Adopting a zero trust model aligns with modern threat landscapes, as it provides a proactive approach to information security.
