Helix focuses on Incident Response & Forensics tools. It is meant to be used by individuals who have a sound understanding of Incident Response and Forensic techniques. Helix has been modified to specifically not touch the host computer and be forensically sound. Helix also has a special Windows autorun side for Incident Response. Helix is now used by SANS for training in Track 8: System Forensics, Investigation and Response.
