MAC Security (MACsec) allows authorized systems in a network to transmit data confidentially and to protect against data transmitted or modified by unauthorized devices.
You can use MACsec on access switches to secure host-to-switch connectivity, and host-to-switch connectivity in an environment where both trusted and untrusted hosts coexist.
In addition to host level authentication, MACsec capable LANs provide data origin authentication, data confidentiality, and data integrity between authenticated hosts or systems. MACsec protects data from external hacking while the data passes through the public network to reach a receiver host.
MACsec enabled hosts encrypt and decrypt every frame exchanged between them using a MACsec key. The source MACsec host encrypts data frames, and the destination MACsec host decrypts the frames, ensuring delivery of the frame in its original condition to the recipient host. This ensures secure data communication.
