A corporate network administrator is configuring access control on the switches to allow only authorized devices to connect to the LAN. The administrator wants to dynamically assign VLANs based on user identity and prevent unauthorized network access at the port level. Which of the following should be implemented?
Setting up Layer 7 firewall rules to assign VLANs
Implementing 802.1X on the network switches
Utilizing port security with MAC address filtering on the switches
Configuring a WAF (Web Application Firewall) for VLAN assignment
802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN. By using 802.1X, network access can be controlled at the port level and, with the proper backend support through RADIUS or a similar authentication server, VLANs can be assigned dynamically based on user identity, which is the requirement in this scenario.
