NAC technology intercepts network traffic coming from devices that connect to a wired or wireless network and verifies that the system and user are authorized to connect to the network before allowing them to communicate with other systems. In this video, learn how 802.1x and network access control restrict the use of a network.
- [Instructor] Network administrators normally need…to restrict network access to authorized users…and ensure that users only have access…to resources that are appropriate for their roles.…That's where a technology called Network Access Control,…or NAC, plays an important role.…NAC technology intercepts network traffic…coming from devices that connect…to a wired or wireless network…and verifies that the system and user are authorized…to connect to the network before allowing them…to communicate with other systems.…
NAC uses an authentication protocol called 802.1x…to perform these access control tasks.…Here's a look at how it works.…There are three systems involved in any 802.1x transaction.…The first is the device that wishes to connect…to the NAC-protected network.…This device must be running a special piece…of software called a supplicant.…This supplicant is responsible for performing…all of the NAC-related tasks…on behalf of the user and system.…The second device involved in the authentication…is the switch that the device connects to…
