What is computer forensics?
Computer forensics, also referred to as computer forensic science, pertains to evidence that can be found on computers. It is used to investigate computer crime, as well as gather evidence in other types of crime.
The goal is to probe computers using forensically sound methods. Computer forensics is based on data recovery principles and techniques but also involves extra practices and guidelines such that any evidence collected will be legally viable and held up in court. Ultimately, computer forensics investigators seek to identify, preserve, recover, and analyze pertinent data, and present facts and opinions about the information.
When collected correctly, digital evidence is considered reliable in many court systems. Computer forensics has been used to help convict criminals for decades and has featured in a wide range of cases including prosecutions for murder and kidnapping.
The terms ‘digital forensics’ and ‘computer forensics’ are often used interchangeably. However, computer forensics is really a branch of digital forensics. Computer forensics covers computers such as desktop PCs and laptops, whereas digital forensics pertains to all digital media, including smartphones, hard drives, flash drives, digital cameras, and more.
