DAI

Dynamic ARP Inspection (DAI) is a security feature that can intercept ARP packets in a network and filter out invalid ARP packets that bind an IP address with an invalid MAC address. This security feature can protect a network from certain Man-In-The-Middle attacks. But, how does this Dynamic ARP Inspection (DAI) work, and how does it protect a network from Man-In-The-Middle attacks? In this article, we would discuss that in detail.
