Field Report
Investigators must ensure the integrity of all evidence collected, analyzed, processed and presented to a courtroom and jury. The reason that this is important is because the improper collection and analysis of evidence can lead to compromised data and potential damage to a prosecution. The seizure and analysis of digital evidence can be particularly challenging but is just as critical to a case as physical evidence. There are specific procedures that must be met to ensure the successful collection and analysis of digital media and guidelines or best practices for collection of all evidence, both physical and digital that must be followed. Conducting the proper steps in an investigation regarding the collection and processing of evidence and the proper chain of custody requirements can ensure a successful outcome in solving a case and a successful prosecution.
The first and most important step in the entire process for collecting evidence is to document the scene. It is extremely critical that an investigator capture as accurate a depiction of a crime scene as possible (Solomon, Rudolph, Tittel, Broom, & Barrett, 2011). This can be accomplished in a number of ways. These include taking a photograph of the scene to preserve the original image of the scene for a judge and jury. Investigators can also take images of a computer system. It is necessary to take hash images of volatile data first as volatile data relies on a constant flow of electricity to keep in system memory. Things that are considered volatile are registers, the system casche, routing tables, kernel statistics, memory, temporary file systems, disks and archived media (Soloman, Rudolph, Tittel, Broom, & Barrett, 2011). The first thing an investigator s...
