1 Course: Network Traffic Analysis Duration: 5 Day Lab & Lecture Course Price: $ 3, Description: Network Traffic Analysis will enable students to differentiate between normal and abnormal network traffic. The course focuses on research, filtering and comparative analysis to identify the different types of activity on a network and attribute their source. A subject matter expert will teach you security-related tactics, techniques and procedures for performing network analysis in todays ever-changing threat landscape. Youll learn to follow conversations through redirection as well as how to develop custom filters for nondissected protocols. After attending this course, students will be able to hone in on the key events in a traffic capture and reconstruct the event time line. Objective: Upon completion of this course, you will be able to perform the following tasks: Internet Based Open Source Research Wireshark Protocol Analyzer Effective Capture and Display Filtering Tracing System, Service and User Transactions Recognizing Encoding Types Base-64 and URL Encoding Non-Dissected Protocol Analysis HTTP Header Analytics (User-Agents, Referrers, Accept Lines, etc) Cookie Tracking Prerequisites: You should possess knowledge of the following: A Broad Understanding of TCP/IP and Associated Protocols Knowledge of Network Hardware and Segment Types Previous Exposure to Wireshark or Other Protocol Analysis Software is also recommended NTA Page 1/6

2 Who Should Attend: Network Analysts seeking to develop security-related skills Incident Responders needing to quickly address system security breaches Penetration Testers looking to reduce their detectability Threat Operations Analysts seeking a better understanding of network intrusions All Network Administrators needing a better understanding of network security NTA Page 2/6

Students will work in small groups to identify traffic and reconstruct the topology of an unknown environment. The teams will have to decipher obfuscated transactions and map observed activities back to the respective user. More Tools and Tricks Capsa7, NetWitness Investigator, Network Miner Student Practical Demonstration: Using the tools, skills, and methodologies taught in Days 1-4 of the class, students will participate in a competative capture-the-flag exercise. Designed to challenge the participants, each correctly completed milestone will unlock a successively more difficult challenge. NTA Page 6/6
