Digital Forensics

Digital Forensics (also known as Cyber Forensics) is a branch of forensic science pertaining to legal evidence found in computers and digital storage media.The goal of Digital forensics is to explain the current state of a digital artifact. The term digital artifact can include any system, device or document which can store or transmit digital information. Digital forensics is seen more as a tool used to investigate the chain of events once the crime has taken place. But it needs to be seen as a preemptive measure to stop crime or terror incidents. Hence, a two-way consolidated model needs to be put in place to track terrorist activities and curb criminals.
