Spiral Model for Digital Forensics Investigation

Abstract

Digital forensics is the scientific analysis of digital crimes. It is analogous to physical crime scene investigation, which usually consists of collecting evidences, storing them at a proper place, documenting them, creating a hypothesis for the crime scene to analyze the situation, and presenting them before the court of law for jurisdiction. But, while dealing with things digitally, a proper framework is needed which should be applicable for all the crime scenes and for all the digital devices like mobile phones and computers, etc. This paper proposes a framework based on the spiral model of software development, which consist of risk analysis factor also for providing flexibility so that it can overcome all the drawbacks of previous methodologies. The biggest advantage of this method is its ability to plan next phase as per the outcome of previous phase because of its agile functioning and spiral behavior, to perform investigation as quickly as possible. It covers all the phases in the form of different iterations. Hence, this paper proposed a generic framework to perform digital forensics smoothly without any drawback at all.
