I started working in digital forensics and incident response (DF/IR) in 2004 when I founded a high-tech crimes unit for a municipal police department. Seven of my eleven years in law enforcement were spent investigating cyber crime and performing digital forensics for local, state, and federal agencies. The unit I started eventually grew from a one-person high-tech crimes unit into an ASCLD/LAB accredited ten-person federal cyber crime task force of which I was the commander and laboratory director. I was responsible for managing people, equipment, budgets, grants, investigations, forensics, and all other aspects of the operations. My career path has given me some unique opportunities and experiences, allowing me to have a perspective into many areas of DFIR, Information Security (InfoSec) and cybersecurity.

Here you will find a variety of resources related to digital forensics and I hope it is helpful.  If you have questions or comments, please post them.
