Network Traffic Analysis Training

Introduction:

Network Traffic Analysis Training - Public Courses and Onsite

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.

With Network Traffic Analysis Training, you will also 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 time line.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.

Audience/Target Group

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
