Deductive, inductive and abductive reasoning in the context of cyber forensics analysis.

Deductive Reasoning
Hurley mentioned (2000, p. 33), deductive reasoning is “an argument in which the premises are claimed to support the conclusion in such a way that it is impossible for the premises to be true and the conclusion false”. This equates to say that if all the premises are firm and accurate, the conclusion is most definitely firm and correct (Walton, 2005).
Conclusion drawn from deductive reasoning is derived from the given premises. The reasoning moves from general principles to a specific conclusion when utilized by the criminal justice profession (Turvey, 2001).
One of the most well-known deductive reasoning is the Locard exchange principle; Kirk (1953) defined this principle as
"Wherever he steps, whatever he touches, whatever he leaves, even unconsciously, will serve as a silent witness against him. Not only his fingerprints or his footprints, but his hair, the fibers from his clothes, the glass he breaks, the tool mark he leaves, the paint he scratches, the blood or semen he deposits or collects. All of these and more, bear mute witness against him. This is evidence that does not forget. It is not confused by the excitement of the moment. It is not absent because human witnesses are. It is factual
