  Research in the field of network forensics is gradually expanding with the
propensity to fully accommodate the tenacity to help in adjudicating, curbing
and apprehending the exponential growth of cyber crimes. However, investigating
cyber crime differs, depending on the perspective of investigation. There is
therefore the need for a comprehensive model, containing relevant critical
features required for a thorough investigation for each perspective, which can
be adopted by investigators. This paper therefore presents the findings on the
critical features for each perspective, as well as their characteristics. The
paper also presents a review of existing frameworks on network forensics.
Furthermore, the paper discussed an illustrative methodological process for
each perspective encompassing the relevant critical features. These
illustrations present a procedure for the thorough investigation in network
forensics.
