1. Wireshark
a. A study on Wireshark tool and brief about the functions and features of the
tool
Wireshark is a network packet analyzer. A network packet analyzer will try to
capture network packets and tries to display that packet data as detailed as
possible.
You could think of a network packet analyzer as a measuring device used to
examine what's going on inside a network cable, just like a voltmeter is used by an
electrician to examine what's going on inside an electric cable (but at a higher
level, of course).
In the past, such tools were either very expensive, proprietary, or both. However,
with the advent of Wireshark, all that has changed.
Wireshark is perhaps one of the best open-source packet analyzers available
today.
Here are some examples people use Wireshark for:
• Network administrators use it to troubleshoot network problems
• Network security engineers use it to examine security problems
• QA engineers use it to verify network applications
• Developers use it to debug protocol implementations
• People use it to learn network protocol interna
