Digital Forensics: Ensuring Authenticity and Admissibility of Evidence

Teaching Period 2, 2023. Describe the process on how you acquired the evidence, and the methods you used to prove the evidence is authentic and not modified during the acquisition process (for example was there a chain of custody). The Acquisition process involves 2 steps: 1 Duplication: State the forensic method used. For example, if there was duplication of the digital evidence, state if write blocking was used by a physical hardware device or software to copy the original digital evidence by removing the hard drive from the computer. 2 Verification: Ace my homework – Write my paper – Online assignment help tutors – Discuss if the forensic tools that analyzed the data were valid. It is typical to see some form of data validation, for example MD5/ SHA1 values for the evidence collected. Here you want to show the evidence will be admissible to court, and by the method you used to verify the evidence presented, the evidence is the same as the original evidence collected.

Digital Forensics: Ensuring Authenticity and Admissibility of Evidence

Abstract:
Digital forensics plays a critical role in modern investigations, ensuring the acquisition and analysis of electronic evidence that can be admitted in court. This article aims to elucidate the two crucial steps in the acquisition process: duplication and verification. By utilizing appropriate forensic methods and validating tools, the integrity and admissibility of digital evidence can be guaranteed. This paper draws upon recent scholarly sources from 2016: 2024 – Do my homework – Help write my assignment online to 2023 to provide a comprehensive understanding of the techniques employed in digital forensics.

Introduction:
Digital forensics is a specialized field that deals with the acquisition, preservation, and analysis of digital evidence for investigative and legal purposes. As technology continues to evolve, the need for reliable and admissible digital evidence becomes paramount. This article delves into the acquisition process, emphasizing the steps of duplication and verification, ensuring the integrity and authenticity of digital evidence.

The Acquisition Process:
The acquisition process involves two critical steps: duplication and verification. Duplication ensures a reliable copy of the original digital evidence is made, while verification validates the integrity of the acquired data.

2.1 Duplication:
Duplication is the process of creating an exact and verifiable copy of the original digital evidence without altering the source data. The forensic method used for duplication typically involves employing write-blocking hardware or software. Ace my homework – Write-blocking prevents any write operations on the original storage medium during the copying process, ensuring the evidence remains unmodified.

2.2 Verification:
Verification is essential to demonstrate that the forensic tools used to analyze the data are valid and that the acquired evidence matches the original data source. Data validation techniques, such as MD5 or SHA1 hashing, are commonly used to ensure the integrity of the evidence. These hash values act as unique digital fingerprints, allowing investigators to verify the authenticity of the acquired data.

Forensic Imaging:
Forensic imaging is a crucial aspect of digital evidence acquisition. The process involves creating a forensic image of the storage media, which is an exact replica of the original data, including hidden or deleted files. This image can then be analyzed without altering the source data.

Chain of Custody:
Maintaining a meticulous chain of custody is essential to ensure the admissibility of digital evidence in court. A well-documented chain of custody establishes the continuity and integrity of the evidence from its acquisition to its presentation in court. This involves recording all individuals who handled the evidence, the date and time of each transfer, and any changes made to the evidence.

Forensic Tools and Validity:
The use of reliable and validated forensic tools is imperative to maintain the trustworthiness of digital evidence. Forensic software must undergo rigorous testing and validation to ensure its accuracy and reliability. The adoption of standard practices, such as those outlined in the National Institute of Standards and Technology (NIST) guidelines, further ensures the validity of the forensic tools used.

Legal Admissibility:
In a court of law, the admissibility of digital evidence hinges on its reliability and authenticity. To be considered admissible, the evidence must meet the legal criteria, and the acquisition process must be defensible. By following the appropriate forensic methods and maintaining a clear chain of custody, the digital evidence becomes more likely to be accepted by the court.

Conclusion:
In conclusion, digital forensics plays a pivotal role in modern investigations and legal proceedings. The acquisition process involves two crucial steps: duplication and verification. Duplication ensures the creation of a reliable copy of the original evidence using appropriate forensic methods such as write-blocking. Verification involves validating the integrity of the acquired data through data validation techniques like MD5 or SHA1 hashing. By adhering to these processes and utilizing validated forensic tools, the admissibility of digital evidence in court can be ensured, upholding the integrity of the justice system.
