As a digital investigator for your local sheriff’s department, you have been asked to go with a detective to a local school that got a bomb threat in an anonymous e-mail. The detective already has information from a subpoena sent to the last known ISP where the anonymous e-mail originated, and the message was sent from a residence in the school’s neighborhood. The detective tells you the school principal also stated that the school’s Web server had been defaced by an unknown attacker. The detective has just obtained a warrant for the search and seizure of a computer at the residence the ISP identified. Prepare a list of what items should be included in an initial-response field kit to ensure the preservation of digital evidence when the warrant is carried out. Please write at least one page.

Title: Case Project 4-4: Initial-Response Field Kit for Preservation of Digital Evidence

As a digital investigator working alongside a detective to investigate a bomb threat at a local school, it is imperative to ensure the preservation of digital evidence during the execution of a search and seizure warrant. This document outlines the items that should be included in an initial-response field kit to facilitate the preservation and collection of digital evidence by the investigating team.

1. Digital Forensics Toolkits:
1.1 Write-Blockers: Write-blocking hardware devices that prevent the alteration of data on storage media devices while allowing read-only access. Including write-blockers ensures the integrity of any collected evidence without inadvertently damaging or modifying data on the suspect’s computer system.
1.2 Forensic Imaging Software: Software such as FTK Imager or EnCase that enables the creation of forensic images (bit-by-bit copies) of storage devices. These tools are crucial for preserving evidence in a forensically secure and unalterable format.

2. Collection and Packaging Tools:
2.1 Antistatic Bags: Essential for safely storing storage media, such as hard drives or removable media, to mitigate the risk of physical damage or static charges causing data corruption.
2.2 Evidence Bags: Large, tamper-evident bags designed to securely store computers, computer peripherals, and other digital evidence items. These bags should be properly sealed and labeled to maintain the chain of custody.
2.3 Protective Gloves: Non-contaminating gloves that prevent contamination of evidence and ensure the integrity of digital media being handled.

3. Documentation Equipment:
3.1 Digital Camera: A camera capable of capturing high-resolution images for the purpose of documenting the physical setup, condition, and connections of computer systems and any relevant physical evidence at the suspect’s residence.
3.2 Notebook and Pens: An essential tool for documenting the search process, including details such as the location of evidence, timestamps, and any notable observations that may aid in the investigation. Ensure the ink used is archival and cannot be erased or altered.
3.3 Evidence Tags: Pre-numbered tags used for labeling and tagging each piece of evidence to maintain the chain of custody. These tags should include details such as the case number, date and time of collection, and the investigator’s initials.

4. Miscellaneous Tools:
4.1 USB Drives: Portable storage devices to securely transfer digital evidence from the suspect’s computer system to a forensic lab for further analysis.
4.2 Laptop/Desktop Computers: In case an on-site investigation is required, having a secure and forensically preserved separate computer system can be beneficial for live analysis or remote evidence acquisition.
4.3 Network Cable and Adapters: Essential for establishing network connectivity during the investigation, enabling the retrieval or downloading of digital evidence from networked devices.

A comprehensive initial-response field kit is crucial to ensure the effective preservation of digital evidence during a search and seizure operation. The items listed above provide necessary tools for digital investigators and law enforcement personnel to collect, document, and package digital evidence in a manner that preserves its integrity and chain of custody. By utilizing these tools, investigators can ensure the successful and secure collection of pertinent evidence for further examination and analysis in solving the case.
