Zero Trust Network Access (ZTNA) is a security framework that addresses the shortcomings of traditional network security approaches. Unlike conventional models that rely on perimeter defenses, ZTNA assumes that threats can originate from both internal and external sources. This model prioritizes the verification of user and device identities before granting access to applications and resources, thereby reducing the risk of unauthorized access and lateral movement within the network.
ZTNA implements the principle of least privilege, which restricts user access to only the specific resources necessary for their job functions. This approach minimizes the attack surface and limits the potential impact of security breaches. Furthermore, ZTNA utilizes micro-segmentation to create isolated network segments, providing an additional layer of containment for potential threats.
By adopting ZTNA, organizations can strengthen their overall security posture and more effectively protect their sensitive data and critical assets.
