In digital forensics the  process requires two levels of personnel having specialized training and knowledge to deal with their type of work.

A digital forensic technician gathers or processes evidence at crime scenes. The technician needs to be trained on the correct handling of technology.

Then you have examiners who specialize in one area of digital evidence, either at a broad level for example computer or network forensic, or as a sub-specialist that is  image analysis.

The internet is a big thing today.  This is a very useful commodity, but with it’s usefulness it also brings in problems. A lot of people exploit technology for their own ends and almost 80% of crime today has a digital finger print.  This is where digital forensics comes in.
