What is "digital forensics"?

Digital forensics is the process for the preservation, extraction, analysis, and presentation of digital information for its use as evidence in a legal proceeding. Protecting the integrity of the information so that it can be admitted as evidence in a court proceeding is always paramount during the process.

“Digital forensics” started out as “computer forensics.” Today, digital forensics has grown to encompass computer forensics, media forensics, and network forensics. Forensic examination of computers has expanded to include many other processor-based devices; e.g., PDAs, cell phones, and digital cameras. However, the goal of digital forensics has remained the same — find useful information and collect it in a manner that insures its admissibility as evidence.
