DEFT 8.1 Is a Forensic Distro Used by Law Enforcement to Catch Bad Guys
DEFT stands for Digital Evidence & Forensic Toolkit and is based on Lubuntu. It's a set of tools used by law enforcement agencies during computer forensic investigations.
“Computer Forensics software must be able to ensure the integrity of file structures and metadata on the system being investigated in order to provide an accurate analysis. It also needs to reliably analyze the system being investigated without altering, deleting, overwriting or otherwise changing data,” reads the official website.
