Final answer:
IEEE 802.1X is a network access control framework widely used on networks that adhere to the IEEE 802.11 standard. It is utilized to authenticate users before granting network access, providing a high level of security by restricting unauthorized users' access to network resources.
Step-by-step explanation:
IEEE 802.1X is a standard for network access control, primarily used on networks that use the IEEE 802.11 standard, such as wireless networks (Wi-Fi). It provides an authentication framework for wired and wireless LANs, allowing network administrators to restrict users' access to network resources at the port level. Essentially, before a user or device is given a legitimate IP address and full network access, they must first authenticate themselves.
IEEE 802.1X operates by packaging and sending a user's credentials from their device to an authentication server. This conversation between the device and the server relies on the Extensible Authentication Protocol (EAP). Once the user's identity is verified and accepted, the network opens a port for access.
This protocol provides a high level of network security, mitigating the risks associated with unauthorized users gaining access to sensitive information within the network.
