Computer forensics is a branch of digital forensic science that deals with evidence found in computers and digital storage media. It involves using investigative techniques to identify and store evidence from a computer device, which can be used in a court of law. Computer forensics is used to investigate a wide variety of crimes, including child pornography, fraud, espionage, cyberstalking, murder, and rape. It is also used in civil proceedings as a form of information gathering.

Computer forensics involves similar techniques and principles to data recovery, but with additional guidelines and practices designed to create a legal audit trail. The goal of computer forensics is to perform a structured investigation and maintain a documented chain of evidence to find out exactly what happened on a computing device and who was responsible for it.

Some common types of computer forensics include network, mobile device, and digital forensics. Network forensics involves the analysis of network traffic to identify and investigate security incidents, such as hacking attempts or data breaches. Mobile forensics involves the retrieval and analysis of data like messages, photos, videos, audio files, and contacts from mobile devices. Digital forensics involves the retrieval and analysis of data from digital sources such as databases, emails, and computer memory.

Computer forensics is important in solving crimes and other legal issues, as computers and other data-collecting devices are used more frequently in every aspect of life. It is a rapidly growing field that offers ample career opportunities for students interested in integrating technology and law.
