QuestionQ39

Data Collection and Sources of Threat Intelligence

Sarah, a forensic investigator, is handling a criminal case. She was provided with all of the suspect devices. Sarah uses imaging software to duplicate the original data from the suspect devices. However, the tool she used could not image the data because the suspect version of the drive was very old and incompatible with the imaging software. Therefore, Sarah used an alternative data-acquisition technique and successfully imaged the data.

Which of the following data-acquisition techniques did Sarah use in this scenario?

  • A Sparse acquisition
  • B Bit-stream disk-to-disk
  • C Bit-stream disk-to-image-file
  • D Logical acquisition
Explanation

A bit-stream disk-to-disk acquisition directly copies the contents of the source media to another disk and is the alternative when a bit-stream disk-to-image-file acquisition cannot be created because of hardware or software incompatibility. It preserves a complete bit-level duplicate rather than limiting collection to selected files or folders.
