Due to the increased number of computer related and cyber crimes reported in third world countries, within the past few years, digital forensics has become a key area in law enforcement. A digital forensic framework compatible with a country’s legislation is a must when digital forensics is used in investigating crimes.
This paper is a review of several digital forensic frameworks / models that currently exist in order to develop an abstract digital forensic process model that would be suitable to be used with the current legislation of Sri Lanka. It identifies core areas of different forensic models and explains why some activities addressed in them become impractical in the context of Sri Lanka. The paper uses several computer related crime and cyber crime cases reported since the year 2003 to justify the authors’ views.
