Forensics (3 day course)
3-Day instructor led course focused on systematic and efficient examination of computer media using X-Ways Forensics.
Complete and systematic coverage of all computer forensics features in WinHex and X-Ways Forensics. Hands-on exercises, simulating most aspects of the complete computer forensics process. Attendees are encouraged to immediately try newly gained insights as provided by the instructor, with sample image files. Many topics are explained along with their theoretical background (e.g. how .e01 files work internally, how hash databases are internally structured, how deleted partitions are found automatically, with what methods X-Ways Forensics finds deleted files). Other topics are forensically sound disk imaging and cloning, data recovery, search functions, dynamic filtering, report creation, ... Emphasis can be put on any aspect suggested by the participants. You will receive complete printed training material for later repetition. Prerequisite: basic knowledge of computer forensics.
The students will learn e.g. how to get the most thorough overview conceivable of existing and deleted files on computer media, how to scan for child pornography in the most efficient way, or how to manually recover deleted files compressed by NTFS which would not even be found by conventional file carving techniques.

It is the goal to be able to draw sustainable conclusions from the data and metadata stored on or seemingly deleted from media to answer to specific problems while documenting the proceedings in a manner acceptable in court.
Examples:"What documents were altered on the evening of January 12, 2005?"
"What pictures were hidden with what method, where and by whom?"
"Who viewed which web pages on what day?"
"Which MS Excel documents saved by Alan Smith contain the keyword 'invoice'?"
