Computer forensics is to examine computers in a forensically sound manner with the aim of identifying, preserving, recovering, analyzing and presenting facts and opinions about the computer information with the intent of using it as evidence in a civil or legal case.
The analysis is executed via a methodical approach to verify factual information within civil or criminal matters.
Today’s computers are powerful machines, allowing us to literally hold the world at our fingertips. The computers that we use every day are capable of storing infinite amounts of data and information about organizations and individuals around the world.
Of course, with the many great advancements that technology has brought to our society, it has also created new opportunities for crime and fraud, and the invention of encrypted software has made it harder for investigators to mine computers and storage devices for valuable information and evidence.
Forensic experts play a critical role in revealing the truth behind the scene of a case, computer forensic specialists are essential to investigating computer-related cases that occur behind the screen.
The purpose of computer forensics techniques is to search, preserve and analyze information on computer systems to find potential evidence for a trial. Many of the techniques detectives use in crime scene investigations have digital counterparts, but there are also some unique aspects to computer investigations.
Computers are getting more powerful, so the field of computer forensics must constantly evolve. In the early days of computers, it was possible for a single detective to sort through files because storage capacity was so low. Today, with hard drives capable of holding gigabytes and even terabytes of data, that's a daunting task. Detectives must discover new ways to search for evidence without dedicating too many resources to the process.
