802.1x Authentication stands as a pivotal protocol within the realm of network security, meticulously designed to bolster the protection of networks—big or small. Its framework empowers network administrators to enforce a robust access control, ensuring that only authenticated users and devices can connect to the network services. At its core, 802.1x employs a client-server model to authenticate users, leveraging the Extensible Authentication Protocol (EAP) to facilitate a versatile range of authentication methods.

EAP-Transport Layer Security (EAP-TLS) is a widely respected protocol that stands at the forefront of secure network access and authentication. Unlike other security mechanisms that may rely on less secure, password-based authentication methods, EAP-TLS leverages the robustness of digital certificates. This means each participant in the communication process must present a valid certificate, ensuring that all parties are precisely who they claim to be.
