Wire Shark is a very powerful and popular network analyzer for Windows, Mac and
Linux. It’s a tool that is used to inspect data passing through a
network interface which could be your ethernet, LAN and WiFi. The series of data that Wireshark inspects are called ‘Frames’ which includes ‘Packets’. Wireshark has the ability to capture all of those packets
that are sent and received over your network and it can decode them for
analysis. When you do anything over the Internet, such as browse
websites, use VoIP, IRC etc., the data is always converted into packets
when it passes through your network interface or your LAN card.
Wireshark will hunt for those packets in your TCP/ IP layer during the
transmission and it will keep, and present this data, on its’ very own
GUI.It is important to note that whilst this is an excellent tool for a
network administrator that needs to check that their customers sensitive
data is being transmitted securely – it can also be used be used by
hackers on unsecured networks – such as airport WiFi. Moral of the story
at this point is to stay clear of clear text http protocols: that is the best advice we can give. To remedy this we would encourage you to use a Firefox addon called https everywhere or use an SSH or VPN tunnel.
