Software Foundations for Cyber security 2
2 Introduction:
The purpose of this paper is to discuss about Wireshark. Wireshark is a powerful tool
for capturing the network but it also helps to access the unauthorised websites like Facebook,
Instagram, and twitter by logging in (Sanders, 2017). It has the ability to capture each and
individual packets which is sent to the system or is received by the system. Live data of the
Traffic network media like Ethernet, Bluetooth USB, wireless LAN can be captured by using
it and it also captures the data from the wire.
