The core principle of forensic science is Locard's Exchange Principle. Dr. Edmond Locard (the Sherlock Holmes of France) created the concept to show how when any two objects come into contact, there's always a transfer of material between each object, like a suspect leaving behind shoe prints at a crime scene. In the digital realm, this exchange happens as well, like registry keys being modified, system logs, evidence of program execution, etc. We've got new forensics training on the way! Until
