How do you start in digital forensics?
Unlike ethical hacking, which has a wealth of resources (blogs, books, conferences, etc.), I believe that digital forensics is sometimes overlooked.
SANS produces excellent materials (from cheatsheets to full-fledged courses), however, their content can become out of date at times (how to use log2timeline for instance).
I would begin by reading Practical Malware Reverse Engineering (an AWESOME book), followed by the Art of Memory Forensics.
