Wireshark: A Beginners Introduction

Presented at SAINTCON 2019, Oct. 23, 2019, 1 p.m. (120 minutes)

Have you heard your friends or colleagues talk about "sniffing" network traffic? Do you want to know if that new "smart"-X device is actually just a way for companies to "steal" more of your private information. Find out what is really happening on your networks with this introduction to Wireshark, one of the most popular tools used in industry for network analysis. No prior knowledge is necessary. We will start with a brief introduction to Wireshark, its capabilities and uses. Next, we will discuss where and how to monitor your network with Wireshark and what factors affect those decisions. At this point we are now ready to start applying capture filters, display filters, and custom colorization rules to highlight the information we are interested in seeing. We will focus on understanding several popular network protocols including ARP, IP, ICMP, TCP, UDP, HTTP and others. We will also take a look at recently disclosed vulnerability such as the DNS rebinding attacks targeting Roku, Google Home and other devices. The entire workshop will be very hands on with many different sample captures to work from as we identify both normal and abnormal traffic. We will not be doing any live captures.
