The three stages of computer forensics

Computer forensics is a discipline that requires experience, expertise and top-quality equipment. The amount of time and skill that goes into a job like this cannot be overestimated, but there are three key stages to the process: evidence collection, preservation and presentation.

Evidence collection

Information is the essence of any forensic pursuit. Computer forensics is no different, as its the data stored on these electronic devices that investigators diligently seek. Experts search through files, logs, firewalls, caches and more to get the information they need, and it’s their unique responsibility to find any hidden data.

Recovering information is often required when measures have been taken to wipe information or damage devices. Despite this, experts can still extract files and operate computers that have been burned, broken or water-logged.

Discovering and recovering information can sometimes be time-consuming, but in the right hands a computer forensic investigation can uncover a huge amount of evidence.


Unfortunately the justice system often takes more time than we’d like. During this time, it is essential that any evidence is preserved correctly before it can be presented in court.
This means that investigators must follow rigid requirements to ensure that information is gathered properly and stored appropriately. Evidence should remain in its original form, for example, and not be exposed to risk of tampering or theft. These issues may jeopardize the integrity of the information, and subsequently allow for a judge to prevent its appearance in court.
Naturally the end goal of computer forensics is to present the information as evidence.

Digital forensics can be difficult to present in the courtroom however. This is due to the technical skill involved and the advanced knowledge needed to understand how information was collected. It is very easy for experts to forget this fact and therefore many make the mistake of communicating their findings in a way that alienates the jury.
