Introduction

Network Traffic Analysis Training Course Hands-on - Grow Your Analytic Intelligence

In this Network Traffic Analysis Training course, you will learn how to differentiate between normal and abnormal network traffic and focus on research, filtering, and comparative analysis to identify the different types of activity on a network and attribute their source.

You will learn security-related tactics, techniques, and procedures for performing network analysis in today's ever-changing threat landscape. You will learn to follow conversations through redirection as well as how to develop custom filters for non-dissected protocols. After completion of this Network Traffic Analysis Training course, you will be able to hone in on the key events in a traffic capture and reconstruct the event timeline.

Duration: 5 days
