Project 2: Investigative Collection Of Evidence

Project 2 Investigative Collection of Evidence

Consider this project a continuation of the work you performed in Project #1. In this portion of the investigation, you are responsible for collecting the physical evidence, documenting, and reporting. You will NOT be handling the digital data during this stage of the investigation. The focus is on the physical handling of digital items/containers. You are to write a report to your supervisor, thoroughly providing a response to both Part I and Part II of the project with properly cited outside research where appropriate. Your report should include a case summary, identification and collection of digital and non-digital evidence, procedures for securing and storing the evidence, and an evaluation of a coworker's evidence documentation. The paper must be formatted as a memo with an APA-style cover page, in-text citations, and a reference list. Each question should be answered with at least one to two paragraphs, demonstrating your knowledge with detailed, research-backed explanations. Use third-person grammar. The document should be 12-point font, double-spaced, with one-inch margins. The final submission should be in a single Word document with answers numbered or clearly separated according to questions. Appropriate references must be included. You should also analyze the adequacy of coworker documentation based on the evidence photos provided. This report is part of an investigative process that involves physical evidence collection, documentation, and securing procedures, in line with digital forensic best practices.

Paper For Above instruction

The investigative process of collecting physical evidence in a digital forensic context requires meticulous attention to detail, adherence to legal and procedural standards, and a systematic approach to evidence handling. This report summarizes a case involving a cyber-related incident within Allied Technology Systems, focusing on investigative procedures performed at the scene of Mr. Jackson’s former workplace. The procedure outlined involves understanding the scope of authority, identification of potential evidence, collection procedures, securing and storing evidence, and evaluating peer documentation accuracy.

Part I: Overview and Case Summary

The incident under investigation pertains to suspected misconduct or cybersecurity breach associated with Mr. Jackson, a former employee of Allied Technology Systems. As the Data Security Analyst, prior to initiating a search within Mr. Jackson’s former work environment, I possess the necessary authority granted through the organization’s incident response protocol, which includes the digital forensics policy and legal considerations. These permissions authorize me to access the relevant work area, seize potential evidence, and document the scene in accordance with existing legal standards for evidence collection (Casey, 2011). The primary objective is to preserve the integrity of evidence while maintaining chain of custody to ensure admissibility in legal proceedings.

Part II: Physical Evidence Acquisition

Identification of Digital Evidence

Upon examining the scene depicted in the Work_Area.jpg, three potential items of digital evidence identified are: (1) a desktop computer, (2) an external hard drive, and (3) a USB flash drive. The desktop computer likely contains user activity logs, files, or configurations pertinent to the investigation. The external hard drive may hold copies of backups or transferred data, and the USB flash drive could contain additional or portable data relevant to Mr. Jackson’s activities.

Collection Procedures for Digital Evidence

1. Desktop Computer: The collection process would begin with documenting its physical condition through detailed photographs and note-taking, emphasizing serial numbers and identifiable marks. To prevent tampering, the computer would be powered down using a forensically sound process, such as cold shutdown, to avoid altering data. The case and peripheral devices would be sealed in an evidence bag, ensuring minimal handling. A write-blocker would be used later during forensic imaging to create a bit-by-bit copy, preserving data integrity (Rogers et al., 2010). The original device remains secured, while the copy serves for analysis.
2. External Hard Drive: Similar initial documentation and photographing would be performed. The drive would be disconnected using antistatic measures, such as wearing an anti-static wrist strap and handling by the edges to prevent electrostatic discharge damage. The drive would then be sealed in an anti-static evidence bag and labeled. A forensic image would be performed with a write-blocker system to ensure the original hardware remains unaltered.
3. USB Flash Drive: The device would be carefully removed using gloves, and its serial number and physical condition documented. It would also be sealed in an evidence bag and labeled with chain-of-custody forms. Forensic imaging would be performed using a write-blocker to preserve the data content.

These steps ensure careful handling, avoid contamination or data alteration, and preserve the forensic integrity of evidence, which is essential for admissibility in court. The potential use of these digital items involves recovering user activity logs, files, and transferred data, which could serve as key evidence linking Mr. Jackson to misconduct or cyber activities, thereby supporting the prosecution’s case (Casey, 2011).

Identification of Non-Digital Evidence

Within the same scene, three non-digital potential items of evidence include: (1) a handwritten notebook, (2) a stack of printed documents, and (3) a set of security access keys. Collection procedures for these items involve wearing gloves, photographing each item in situ, and carefully placing the evidence in separate, labeled paper bags or envelopes to prevent cross-contamination. The handwritten notebook would be seized with its pages intact, ensuring any notes relevant to the investigation are preserved. Printed documents would be collected with care to avoid tearing, and the keys would be bagged securely to prevent loss.

Their potential utility includes revealing handwritten notes that may contain passwords or instructions, documents that corroborate or refute digital evidence, and security keys that could validate access logs or physical access attempts, all strengthening case integrity (Lennert, 2012).

Security and Storage of Evidence

Post-collection, all seized evidence from digital and non-digital sources is labeled with unique identifiers, signed, and stored in a secure evidence room with restricted access. Digital evidence is maintained on encrypted external drives stored within a secure, climate-controlled environment with environmental controls like temperature and humidity regulation to prevent degradation. Physical evidence is stored in locked cabinets, with access only granted to authorized personnel. Chain of custody documentation is strictly maintained, and logs are updated for each transfer or handling event to preserve evidentiary integrity (Rogers et al., 2010).

Analysis of Coworker Evidence Documentation

Based on the Evidence Custody Document and accompanying photographs, the coworker attempted to document the seizure of three items. While the descriptions include basic identifiers such as item type and serial numbers, they lack detailed descriptions such as physical condition, specific location within the scene, and any unique markings. To improve, descriptions should include detailed physical descriptions, measurements, and condition notes. For example, instead of simply stating “external hard drive,” an improved description would specify “Seagate 2TB external hard drive, black casing, serial number XYZ123456, with minor scratches on the surface.” This level of detail helps ensure accuracy, completeness, and clarity in evidentiary documentation, which is crucial in court proceedings (Hutt, 2015).

Conclusion

Effective evidence collection in digital forensics relies on meticulous procedures that safeguard the integrity of evidence while enabling successful prosecution. Proper identification, careful collection, secure storage, and thorough documentation are fundamental to building a credible case. Additionally, peer reviews of evidence documentation enhance the overall reliability of forensic investigations. Adhering to best practices in evidence handling and chain of custody ensures that digital and physical evidence remain admissible and compelling in any legal proceedings.
