Technical Issues Lots of info to be recovered in in deleted file space Partial data recovery: does this give us hints to missing data? Prosecutorial view vs. in-house investigation Data dependencies
Technical Issues, II Understanding the OS data structures is important for getting the data of interest Some of the science is actually art: not everything can be automated in a tractable manner
Legal Issues Preserving privacy for multi-user machines: only investigate the suspects: need tools to grab only the relevant data Scope of search: warrant amendment when new evidence surfaces
Policy Issues Acceptable use policies in corporate settings: make sure policies are in place BEFOREHAND so that there isnt a privacy problem collecting the data
Near Term Goals Development of toolkits to recover Collaboration among forensic examiners to suggest tool features LE needs tools to help do the job faster (huge hard drives; lots of cases): do image and hash in parallel; analyze while making image?
Longer Term Tools that implement expert systems Provide way to script rules for newly formed forensics techniques
