Forensics Tools

Forensic tools give cybersecurity analysts the ability to investigate cybersecurity incidents, obtain evidence, and document the chain of custody for that evidence. The use of proper forensic tools is critical to the integrity of cybersecurity investigations and the admissibility of digital forensic evidence in court.

Hashing

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. They may later repeat this hashing process to confirm that the evidence was not tampered with between the time of collection and the time of analysis or the time of introduction into evidence in court.

The two major hash functions used by forensic analysts are Message Digest 5 (MD5) and the Secure Hash Algorithm (SHA). Tools that implement each of these hash functions...
