Hardware Protocol Analyzers
Before we go into further details of sniffers, it is important that we discuss about hardware protocol analyzers. These devices plug into the network at the hardware level and can monitor traffic without manipulating it.
● Hardware protocol analyzers are used to monitor and identify malicious network traffic generated by hacking software installed in the system.
● They capture a data packet, decode it, and analyze its content according to certain rules.
● Hardware protocol analyzers allow attackers to see individual data bytes of each packet passing through the cable.
These hardware devices are not readily available to most ethical hackers due to their enormous cost in many cases.
