Advanced framework for digital forensic technologies and procedures

Area of Science:

• Computer Science
• Information Security
• Law

Background:

• Global networks are evolving towards service-oriented architectures and sensor networks, including the Internet of Things.
• These trends introduce complexities and potential for abuse, necessitating advanced digital forensics capabilities.
• Existing digital forensics approaches require enhancement to provide admissible evidence for legal proceedings.

Purpose of the Study:

• To propose a holistic framework for digital forensics that fosters international consensus.
• To introduce a novel architectural solution addressing core forensic principles.
• To develop a conceptual framework for forensics readiness, supporting proactive evidence collection.

Main Methods:

• A top-down approach, starting from legal, then organizational, and finally technical considerations.
• Deployment of leveled message authentication codes and digital signatures for data integrity.
• Development of a conceptual framework with abstraction levels and procedural guides for investigators.

Main Results:

• A new architectural solution enhances data integrity, easing forensic investigations on attacked systems.
• A conceptual framework for forensics readiness provides structured guidance for proactive digital evidence collection and preservation.
• The proposed framework aims to stimulate international agreement on "template legislation" for digital forensics.

Conclusions:

• The proposed holistic framework addresses critical needs in digital forensics for evolving network architectures.
• Implementing this framework can lead to harmonized national legislation and improved investigative procedures.
• Enhanced data integrity and structured evidence collection are key to successful digital forensics in modern networks.
