Introduction to Wireshark and a brief overview of the course, stating what one can learn from it along with giving some general info on the subject of network traffic.
Some basic concepts that will come in handy during the course, such as IP addresses, MAC addresses, ports, etc. This tutorial deals with essential terms and concepts needed in order for one to be able to understand the network traffic which will later be captured in Wireshark.
Here you can learn the layout of the OSI model and what sort of traffic can be found at each of the seven layers. Very useful to know not only as general knowledge, but rather instead to save one a great deal of time when going through information contained within the packets.
Here one may see how Wireshark program is installed via Linux terminal. It covers things such as, searching for Wireshark in the repositories, set of terminal commands needed for the installation process and it also deals with possible problems that might occur during the installation.
Introducing a user to Wireshark interface and explaining its various functionalities.
Dealing with a wide range of options such as: interface appearance and layout configuration, filter options, capture modes and so forth.
Dealing with the subject of Wireshark filters, to be more precise this tutorial explain how protocol filters can be applied in order to reduce the amount of redundant packets.
Introducing IP and port filtering options along with explaining the proper syntax to be used. And demonstrating how the capture process can be manipulated to only provide packets which fit specified ranges of filters.
In depth analysis of HTTP packets. Examining the values of various fields of the Wireshark output and looking at the content of an HTTP packet, understanding what sort of information does it contain and what useful things we can extract from it.
Demonstration of how unencrypted traffic can be potentially dangerous, and what sort of sensitive information can be extracted from it.
Demonstrating how Wireshark can be used to confirm and monitor firewall settings and pointing out the similarities between a firewall in Linux (iptables) and Wireshark in terms of traffic filtering.
Short exercise to demonstrate how to spot suspicious or unauthorized traffic and how to put an end to it. Deals with subjects such as: spotting suspicious packets, determining their cause and putting a stop to such traffic.
