Because they allow administrators to view all the traffic on a network, they can be used to diagnose issues and assess performance. When first created, sniffers were (and can still be) very helpful tools for engineers to manage their networks. But in most cases, people opt for sniffing software over hardware. Some sniffers are available as hardware appliances, often built directly into network devices such as routers for convenient management. On the internet, each car is a packet, and the people inside are the data it carries. Imagine internet traffic like real-world traffic: It’s like a series of cars driving on a road, and it ebbs and flows depending on a variety of factors. Sniffers get the job done by capturing and inspecting the data “packets” traveling along a network. These devious little programs go by a variety of names - network probes, wireless sniffers, Ethernet sniffers, packet sniffers, packet analyzers - but no matter what you call them, they all get up to the same mischief: eavesdropping on you.
