Course Overview
Hi everyone. My name is Joe Abraham, and welcome to my course, Getting Started with Packet Analysis. I am an IT security professional and consulting engineer with over eight years of experience in networking and security. You may have heard the term packet analysis at some point throughout your career or education so far. This is an important aspect to almost everything IT related. It is used for troubleshooting, analyzing threats, and for forensic purposes. Because of the lack of knowledge and the growing needs of this skill, everybody in IT should learn it. In this course, we are going to walk through the basics of packet analysis using several different tools in our toolbox. Some of the major topics that we will cover include the structure of datagrams in our environments, how to use our analysis tools, how to interpret the information within a datagram, and how to identify certain risks by looking at datagrams. By the end of this course, you will be able to use these tools to capture and interpret packets on your own. Before beginning the course, you should be familiar with general IT terminology and security concerns within enterprise environments. I really hope you'll join me on this journey to learn all about the datagrams with the Getting Started with Packet Analysis course at Pluralsight.
