Whether for forensic investigations, incident response, or simply data recovery, this workshop will add one more tool to your arsenal. To make sure you come out with a new skill in hand, the course includes a practical workshop simulating a forensics investigation, in which you will be asked to perform data recovery and provide a report on your findings. 

Course duration: 4 hours (4 CPE points)

Pre-recorded, Self-paced

Note: since this class was published in 2017, some technologies have advanced and tools had new versions released. These materials have not been updated, however the concepts and techniques presented remain largely relevant.
