ISO 17747-1:2019

ISO 17747-1:2019 is an internationally recognized standard that provides guidelines and requirements for the creation, verification, and authentication of digital evidence. This technical article aims to provide an in-depth understanding of this standard and its significance in the field of digital forensics.

Background and Scope

The need for a standardized approach to handling digital evidence became evident with the exponential growth of technology and the increasing reliance on digital devices in our daily lives. ISO 17747-1:2019, titled "Information Technology - Digital Capability - Part 1: Process of collection and preservation of electronic evidence," was developed to address these challenges.

This standard encompasses various aspects of the digital forensic process, including the identification, collection, preservation, analysis, and reporting of digital evidence. It provides a framework that ensures the integrity, authenticity, and admissibility of digital evidence in legal proceedings.

Key Principles and Requirements

ISO 17747-1:2019 emphasizes several key principles and requirements that digital forensic practitioners must adhere to:

1. Legal and Ethical Considerations: Digital forensic practitioners must operate within legal and ethical boundaries. They should respect individual privacy rights, obtain proper authorization, and ensure their actions do not compromise the integrity of evidence.

2. Chain of Custody: Maintaining a chain of custody is crucial to establish the integrity and reliability of digital evidence. ISO 17747-1:2019 provides guidelines on how to document and preserve the custody information at each stage of the digital forensic process.

3. Acquisition and Preservation: The standard outlines procedures for the acquisition and preservation of digital evidence. It emphasizes the importance of using verified and validated tools and techniques to ensure accurate and complete data capture.

4. Analysis and Reporting: ISO 17747-1:2019 defines requirements for the analysis and reporting of digital evidence, including methodologies for data extraction, interpretation, and presentation. It emphasizes the need for transparency, objectivity, and the inclusion of necessary contextual information in the reports.

Benefits and Future Implications

ISO 17747-1:2019 plays a critical role in enhancing the reliability and trustworthiness of digital evidence in legal proceedings. It provides a common framework that ensures consistent and standardized practices across different jurisdictions and organizations.

Compliance with this standard not only improves the overall quality of digital forensic investigations but also enhances cross-border collaboration and the exchange of digital evidence between countries. It promotes interoperability and facilitates the acceptance of digital evidence in international courts.

As technology continues to evolve, ISO 17747-1:2019 will require periodic updates to address emerging challenges. It is crucial for digital forensic professionals to stay updated with the latest revisions and advancements in this field to maintain the highest standards of digital evidence integrity.
