Computer Forensics is a relatively new field when compared to other related fields. By contrast, the men and women of the NTSB have been investigating air accidents for as long as there have been airplanes, and well before the advent of computers. Computer Intrusions and Air Disasters share a lot in common. While computer intrusions thankfully seldom involve loss of life or serious injury, just as with Air Disasters, they are cascade failures of people, process and technology. In this talk a look is taken at how Air Disasters are investigated, and how we can apply that to Computer Forensic investigations.
