Sniffer

From The IT Law Wiki

A sniffer is a “[s]oftware tool for auditing and identifying network traffic packets.”^[1] They monitor network traffic on wired or wireless networks and capture packets. Packet sniffers generally can be configured to capture all packets or only those with particular characteristics (e.g., certain TCP ports, certain source or destination IP addresses). Most packet sniffers are also protocol analyzers, which means that they can reassemble streams from individual packets and decode communications that use any of hundreds or thousands of different protocols.
