Packet sniffing is typically done on-demand, using portable packet sniffer devices and usually only collects small volumes of traffic. Packet capture is typically seen as being the “big brother” of packet sniffing. The term packet sniffing is sometimes used as a synonym for “ packet capture” and both do the same thing - it’s simply a matter of scale. Is packet sniffing the same as packet capture? Packet sniffers may also be referred to as a network monitor, network recorder, packet capture system, or network analyzer. The network that the packet sniffer monitors may be a physical network such as an Ethernet LAN, or a virtual or cloud network. Packet sniffers are valuable tools for troubleshooting network outages or performance issues and investigating cybersecurity incidents. Packet sniffing can also be done using a laptop and packet sniffing software – such as Wireshark TM Historically, packet sniffers were small portable appliances that can be plugged into the network to sniff traffic on-demand if there is a suspected network issue. A Packet Sniffer is hardware or software that connects to a network to monitor, analyse, log, and capture all the network traffic.
