The Evolution of Cyber Investigations

Ted Theisen will provide an insightful journey into the evolution of cyber investigations over the past 20 years.  It begins in the early 2000s when he began investigating cyber crime while working as a Special Agent with the FBI, encountering tactics and techniques that seem primitive to today’s standards.  Ted will discuss how increased sophistication of threat actors has changed how cyber investigators approach incident response today.  Finally, this presentation will postulate how cyber investigations will continue to evolve in the future.
