I was going over my notes as I've been studying for SANS 504 and found this little nugget for those who are looking for resources other than the 504 course for GCIH cert.
I found a note that mentioned a booked title "Incident Handling Step by Step" which is an outline of the course, but more material is covered.
My guess is that would be "Computer Security Incident Handling Step by Step" by Steven Northcutt who founded GIAC and Presides over SANS.
