While the use of digital evidence is fairly common in contemporary criminal investigation, there are still relatively few degree programs in computer forensics. A new standard developed by ASTM International Committee E30 on Forensic Sciences provides a road map for post-secondary institutions to develop degree programs in computer forensics. The new standard, ASTM E2678 , Guide for Education and…
