Digital Forensic Certification Practice Exam

Which of the following is NOT typically part of the computer forensics investigation methodology?

1. Evidence preservation

2. Data acquisition

3. File deletion

4. Expert testimony

The correct answer is: File deletion

The investigative methodology in computer forensics includes several critical steps aimed at ensuring a thorough examination and analysis of digital evidence. Evidence preservation is paramount to prevent any alterations or loss of data that may be pivotal to an investigation. Data acquisition involves the process of collecting data from digital devices, ensuring that it is done in a manner that maintains its integrity and prevents any tampering. Expert testimony serves as a crucial aspect as well; forensic experts often provide insights and explanations in court regarding the methodologies used and the findings based on their analysis. File deletion, however, is not a standard part of the computer forensics investigation methodology. Instead, forensic investigators focus on recovering deleted files and analyzing them to gather pertinent evidence. The emphasis on file deletion stands out as a process typically carried out by individuals attempting to erase their digital footprint, not by forensic professionals who seek to uncover and present all relevant data.
