description: Network sniffing refers to using the network interface on a system to
|
|
monitor or capture information sent over a wired or wireless connection. An adversary
|
|
may place a network interface into promiscuous mode to passively access data in
|
|
transit over the network, or use span ports to capture a larger amount of data.
