Zero Trust Network Access (ZTNA) is a security model designed to address the limitations of traditional network security approaches. Unlike conventional models that rely on perimeter-based defenses, ZTNA operates on the principle that threats can originate from both inside and outside the network. This model prioritizes the verification of user and device identities, granting access based on specific policies, regardless of the user’s location or network connection.
ZTNA incorporates various technologies to ensure that only authorized users and devices can access specific resources. These technologies include identity and access management (IAM), multi-factor authentication (MFA), encryption, and micro-segmentation. By implementing these measures, ZTNA minimizes the risk of unauthorized access and lateral movement within the network, making it an effective solution for securing modern IT environments.
The core principle of ZTNA is the assumption of zero trust, meaning that no user or device is inherently trusted, even within the corporate network. Instead, ZTNA emphasizes continuous verification of user and device identities and applies access controls based on specific policies. This approach ensures that only authorized entities can access sensitive resources, enhancing overall network security.
