Digital Forensics is the process of preservation, identification, extraction, and documentation of computer evidence that can be used by the court of law. It is the science of finding evidence from digital media like a computer, mobile phone, server, or network to provide the forensic team with the best techniques and tools to solve complicated digital-related cases.
Digital Forensics is an important part of the Incident Response process in businesses.
A Digital Forensics Investigator follows the evidence and solves a crime virtually:
For example: If a security breach happens at a company that results in data theft. In this situation, a digital forensic analyst would determine how attackers gained access to the network, where they traversed the network, and their action on the network, whether they took information or planted malware. S/he recovers data like documents, photos, and emails from computer hard drives and other data storage devices.
Digital Forensics is an exact science- not the procedures but the results!
