Digital evidence often comes from computers, mobile devices, and digital media that store information required by investigators. That's where forensic investigators use system and file forensics techniques to collect and preserve digital evidence. In this video, learn about system and file forensics, including building images of systems, hashing files, taking screenshots, and conducting media forensics.

Investigators do this by creating copies, or images,…of the physical evidence and then using those images…for forensic analysis.…When a forensic analyst creates an image of a hard drive…or other media, the analyst must connect a device…to the drive and use that device…to copy off the data stored on the media.…Whenever media is connected to a system,…there is always the risk that the analysis process…
