Keith Jones, my friend from Jones, Rose, Dykstra and Associates and Real Digital Forensics coauthor wrote The Real World of Computer Forensics for CMP. It's a good read.
Keith, Curtis (Rose) and I are discussing writing Real Digital Forensics 2, which will be fun to develop. We're considering writing a series of cases involving a single enterprise, but involving a wide variety of incident types and data sources. I don't see the book on shelves before 2008, though. It's a lot of work simply creating the evidence for analysis and inclusion on a DVD.
