An Investigation of Digital Forensic Models Applicable in the Public Sector (A case of Kenya National Audit Office)
Digital forensics is a relatively new field in technology which deals with investigation of computer related crimes. The rapid technological growth poses a serious challenge to traditional paper-based forensic investigations. The use of computer systems and the emergence of youthful and technology savvy employees in the public sector are two challenges faced by forensic investigators. This research project reviewed the current state of computer-related crimes and the need for digital forensics in the public sector. Similarly, several digital forensic models used in computer and mobile phone forensics were reviewed. This study took a descriptive approach. The research covered Kenya National Audit Office which has branches spread across the country. Two types of data were collected. Level 1 data collection involved administering questionnaires to a random sample of KENAO staff. This data was then analyzed using both SPSS and Microsoft Excel. Level 2 data collection involved extracting computer images using Linux Mint. This data was analyzed using Microsoft Excel in level one, and using Pro Discover Basic and the Sleuth Kit, in level two. The results from both Level 1 and Level 2 data analysis were presented in a comparative format using tables, pie charts, and bar graphs and interpreted in form of notes. Finally, limitations and conclusions of the study were drawn and recommendations made based on the results obtained.
