什么是 802.1X 身份验证？
802.1X is an Ethernet LAN authentication protocol used to provide secure access to a computer network. It’s a standard defined by the Institute of Electrical and Electronics Engineers (IEEE) for port-based network access control. As such, its main purpose is to verify that a device attempting to connect to the network is actually what it claims to be. 802.1X is commonly used in enterprise networks to protect against unauthorized access, enforce security policies, and make sure that data transmitted over the network is secure.
802.1X 是一种以太网 LAN 身份验证协议，用于提供对计算机网络的安全访问。  它是电气和电子工程师协会 (IEEE) 为基于端口的网络接入控制定义的标准。因此，它的主要目的是验证试图连接网络的设备的信息是否属实。802.1X 通常用于企业网络，以防止未经授权的访问，实施安全策略，并确保通过网络传输的数据是安全的。
