Toward models for forensic analysis

The existing solutions in the field of computer forensics are largely ad hoc. This paper discusses the need for a rigorous model of forensics and outlines qualities that such a model should possess. It presents an overview of a forensic model and an example of how to apply the model to a real-world, multi-stage attack. We show how using the model can result in forensic analysis requiring a much smaller amount of carefully selected, highly Useful data than without the model.
