Network Forensics and Incident Response with Troy Wojewoda

Incident responders are continually faced with the challenge of collecting and analyzing relevant event data—network communications is no exception. This course uses an assortment of network data acquisition tools and techniques with a focus on open-source, vendor-neutral solutions. Students who take this course will learn how to perform network traffic and protocol analysis that ultimately supports cybersecurity incident response efforts.

From reconnaissance to data exfiltration, network traffic scales to provide a bird’s-eye view of attacker activity. Leveraging the vantage point of key network traffic chokepoints, this course explores nearly every phase of an attacker’s methodology. Students will learn network traffic analysis concepts and work through hands-on lab exercises that reinforce the course material using real-world attack scenarios.
