Zero Trust Network Access (ZTNA) is a security framework designed to address limitations in traditional network security approaches. Unlike conventional models that rely on perimeter-based defenses, ZTNA assumes threats exist both inside and outside the network. This model focuses on verifying user and device identities, granting access based on specific policies regardless of the user’s location relative to the corporate network.
ZTNA operates on the principle of least privilege, granting users access only to resources necessary for their job functions. This approach minimizes the risk of lateral movement by potential attackers within the network. ZTNA incorporates continuous monitoring and adaptive access controls, dynamically adjusting access privileges based on the changing risk posture of users and devices.
By shifting the security focus from the network perimeter to individual users and devices, ZTNA offers a more effective approach in today’s complex and distributed IT environments. Implementation of ZTNA can significantly reduce an organization’s attack surface and enhance overall security posture.
