X-Ways Forensics Training, 4 days

This main training course is focused on the systematic and efficient examination of computer media using our integrated computer forensics software “X-Ways Forensics”. After attending this course, you may start the X-PERT certification process (though taking the advanced course as well, see below, is recommended).
 

Complete and systematic coverage of most 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 (slack space, partially initialized space, how hash databases are internally structured, how deleted partitions are found automatically, with what methods X-Ways Forensics finds deleted files, etc. etc.). Other topics are forensically sound disk imaging and cloning, data recovery, search functions, dynamic filtering, report creation, ... 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, etc. There will be a practical exam at the end of the course, which you can regard as just another exercise for yourself or that you can take more seriously and get scored by the instructor if you like. The exam recapitulates the most important functions of the software and helps you to gauge your proficiency. The results will not be recorded by us in any way. Note that the instructor will present the answers to the test during the final 20 minutes.

• Filtering keywords based on the files they are contained in
• Decoding Base64, Uuencode, etc.

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, 2012?"
"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 word 'invoice'?"
"Which USB sticks were attached to the computer at what time?"
