The use of proper forensic tools is critical to the integrity of cybersecurity investigations and the admissibility of digital forensic evidence in court.


Hash algorithms play an important role in forensic analysis. As discussed in Chapter 7, “Performing Forensic Analysis,” forensic analysts use hash algorithms to create digital fingerprints of files, drives, and other data sources when they are first collected as evidence.
