On digital forensic readiness in the cloud using a distributed agent-based solution: issues and challenges

摘要

The need to perform digital investigations has, over the years, led to the exponential growth of the field of Digital Forensics (DF). However, quite a number of challenges face the act of proving - for purposes of Digital Forensic Readiness (DFR) - that an electronic event has occurred in cyberspace. The problem that this research addresses involves the challenges faced when an Agent-Based Solution (ABS) is used in the cloud to extract Potential Digital Evidence (PDE) for DFR purposes. Throughout the paper the authors have modified the functionality of an initially malicious botnet to act as a distributed forensic agent to conduct this process. The paper focuses on the general, technical and operational challenges that are encountered when trying to achieve DFR in the cloud environment. The authors finally propose a contribution by assessing the possible solutions from a general, technical and operational point of view.
