  • A Usability Analysis of the Autopsy Forensic Browser
    Proceedings of the Second International Symposium on Human Aspects of Information Security & Assurance (HAISA 2008) A Usability Analysis of the Autopsy Forensic Browser D.J. Bennett and P. Stephens Department of Computing (Academic), Canterbury Christ Church University, Canterbury, United Kingdom e-mail: {david.bennett, paul.stephens}@canterbury.ac.uk Abstract This paper reviews the usability of the Autopsy Forensic Browser. Two expert-based usability review techniques are used: Cognitive Walkthrough and Heuristic Evaluation. The results of the evaluation indicate that there are many areas where usability could be improved and these are classified into areas of eight overlapping areas. Examples from each area are presented, with suggestions as to methods to alleviate them. The paper concludes with a future work proposal to effect the changes suggested and retest the current and the replacement system with a user-based evaluation. Keywords Usability, Human-Computer Interaction, Interface Design, Autopsy Forensic Browser, The Sleuth Kit, Cognitive Walkthrough, Heuristic Evaluation 1. Introduction This paper reviews the usability of the Autopsy Forensic Browser tool. The reasoning for this is to improve future versions of the tool. In many ways forensic analysis tools are no different to any other mission critical software in terms of the need for usability. However, failure in usability in such tools could lead to outcomes which deny liberty to innocent persons, or enable criminals to continue with criminal activity should an investigation fail in some way. 1.1. Forensics and the Autopsy Forensic Browser Gottschalk et al. (2005) define computer forensics as the identification, preservation, investigation, and documentation of computer systems data used in criminal activity.

I would like to thank the AAFS staff, the many volunteers, and everyone else who have worked together to create an excellent program for this meeting with the theme Crossing Borders. You will have many opportunities to meet your colleagues and discuss new challenges in the field. There are many workshops and special sessions that will be presented. The Interdisciplinary and Plenary Sessions will provide different views in forensic science—past, present, and future. The Young Forensic Scientists Forum will celebrate its 25th Anniversary and is conducting a workshop related to the meeting theme. More than 1,000 presentations are scheduled that will provide you with more insight into the developments in forensic science. The exhibit hall, always interesting to explore, is where you will see the latest forensic science equipment, technology, and literature. The theme Crossing Borders was chosen by me and my colleagues at the Netherlands Forensic Institute (NFI). We see many definitions of crossing borders in forensic science today. For the 2020 meeting, six words starting with the letters “IN” are included in the theme.

Ogazi-Onyemaechi, Ali Dehghantanha, Kim-Kwang Raymond Choo, “Performance of Android Forensics Data Recovery Tools”, Pages 91-110, Chapter 7, (Elsevier) Contemporary Digital Forensic Investigations Of Cloud And Mobile Applications Performance of Android Forensics Data Recovery Tools Bernard Chukwuemeka Ogazi-Onyemaechi1, Ali Dehghantanha1; Kim-Kwang Raymond Choo2 1School of Computing, Science and Engineering, University of Salford, Manchester, United Kingdom 2 Information Assurance Research Group, University of South Australia, Australia [email protected]; [email protected]; [email protected] Abstract- Recovering deleted or hidden data is among most important duties of forensics investigators. Extensive utilisation of smartphones as subject, objects or tools of crime made them an important part of residual forensics. This chapter investigates the effectiveness of mobile forensic data recovery tools in recovering evidences from a Samsung Galaxy S2 i9100 Android phone. We seek to determine the amount of data that could be recovered using Phone image carver, Access data FTK, Foremost, Diskdigger, and Recover My File forensic tools. The findings reflected the difference between recovery capacities of studied tools showing their suitability in their specialised contexts only. Keywords: Data recovery, digital forensics, deleted file recovery, mobile forensics, Android forensics. 1 1.0 INTRODUCTION Smart mobile devices, particularly smartphones, are increasingly popular in today’s Internet-connected society (1–4). For example, few years ago in 2010, shipments of smartphone grew by 74 percent to 295 million units (3,4). Unsurprisingly, sales of smartphones have been increasing since then (5,6), and it has been estimated that 1.5 billion smartphones will be sold by 2017 and 1 billion mobile subscribers by 2022 (7–15).
