A packet analyzer used for intercepting traffic on wireless networks is known as a wireless analyzer - those designed specifically for Wi-Fi networks are Wi-Fi analyzers. [ a ] While a packet analyzer can also be referred to as a network analyzer or protocol analyzer these terms can also have other meanings.
Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Originally named Ethereal, the project was renamed Wireshark in May 2006 due to trademark issues. [5]
Sniffing attack in context of network security, corresponds to theft or interception of data by capturing the network traffic using a packet sniffer (an application aimed at capturing network packets). When data is transmitted across networks, if the data packets are not encrypted, the data within the network packet can be read using a sniffer. [1]
Bro is a system that detects network attackers and abnormal traffic on the internet. [14] It emerged at the University of California, Berkeley that detects invading network systems. [3] The system does not apply to the detection of eavesdropping by default, but can be modified to an offline analyzing tool for eavesdropping attacks. [3]

A packet capture appliance is a standalone device that performs packet capture. [1] Packet capture appliances may be deployed anywhere on a network, however, most commonly are placed at the entrances to the network (i.e. the internet connections) and in front of critical equipment, such as servers containing sensitive information.

The Sniffer was implemented above Microsoft’s MS-DOS operating system, and used a 40 line 80-character text-only display. The first version, the PA-400 protocol analyzer for Token-Ring networks, [ 21 ] was released on a Compaq Portable II “luggable” computer that had an Intel 80286 processor, 640 KB of RAM, a 20 MB internal hard disk, a 5 ...
