Digital Forensics & Cyber Intelligence

Digital Forensics is a branch of forensic science pertaining to legal evidence found while analyzing  traditional document sources, computers, telephones and other data storage devices. The goal of Digital forensics is to explain the current state of 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 pre-emptive measure to stop crime or terror incidents. The information recovered and analyzed from these sources routinely produces key evidence in court, delivered by expert witness testimony. Digital and document forensics integrates seamlessly with the broad range of services offered by our forensic science teams. Hence, a two-way consolidated model needs to be put in place to track terrorist activities and curb criminals.​
