Abstract-Digital forensic is the study of scientifically proven methods that results in the identification, preservation, collection, validation, analysis, interpretation, documentation and presentation of digital evidence [1]. Just like computer forensics, digital forensic is also a very wide branch. Different tools, techniques, frameworks and models have been presented to study the basics of digital forensics. The focus of this research is to study different models and the steps that have been proposed by the authors in order to implement these models, the steps that are involved in the investigation process and finally make a comparative study that which of the model is the best among them.Index Terms-Abstract model, DFRWS, EIPID, IPID, NOJ.

Abstract-Digital Forensics can be defined as a field of study involving the usage of technical and proved procedures for collecting, preserving, validating, analyzing, interpreting and presenting the Evidences extracted from the digital sources for presenting those in the court of law. Different process models have been proposed by the researchers for cyber crimes' investigation process, each having its own suitability to environments where they are applicable and other pros and cons. The paper includes the tailoring of existing process models to the particular domain of higher education institutes. With the growing access of computing resources and internet to the students, employees and overall citizens, it is the need of time that organizations should establish and maintain their cyber forensics analysis policy along with whole process to be followed in case of any cyber crime scene reporting.
