What is IEEE 802.1X ? It is a robust network access control standard that enhances computer network security. It utilizes port-based authentication, allowing organizations to control network access by authenticating connecting devices. The protocol involves an authentication RADIUS server, a supplicant (client device) that utilizes digital certificates to authenticate themselves , and an authenticator (hardware platform or  hosted service), ensuring only authorized users and devices gain network access, thus preventing unauthorized entry and enhancing network security.

Digital certificates play a pivotal role in the authentication process of IEEE 802.1X. These electronic documents verify the legitimacy of devices and users attempting to connect to the network. Unlike traditional username/password methods, digital certificates offer a higher level of security. They utilize cryptographic keys to establish a secure and trusted communication channel between the client and the authentication server. To further enhance network security, the implementation of digital certificates in IEEE 802.1X allows for the automation of credential verification, significantly reducing the risk of human error and credential theft.

A RADIUS server is a network service that authenticates and authorizes users wishing to access network resources, including LAN network port connections, VPNs, and Wi-Fi. It utilizes a protocol to verify the user's credentials or certificate against a central database. The NetAttest EPS combines RADIUS and digital certificates to offer an off-the-shelf network access control system that provides enhanced security. This integration ensures a seamless and robust authentication process, significantly reducing vulnerabilities and streamlining access management across various network entry points.
