802.11-based wireless networking has invaded cities, offices, homes and coffee shops over the last five years, and has become a widely used and accepted technology. It has revolutionised computer networking and automation and added a social aspect to personal computing. Accompanying this widespread usage is the presence of crime; the more popular technology, the more opportunity exists for its misuse. / This dissertation studied 802.11-based wireless networking environment from a forensic computing perspective. It sought to understand the current state of wireless misuse: present misuses; potential forms of misuse involving 802.11-based wireless networks; and current tools and techniques used in its identification, containment and analysis. The research highlights the lack of current tools and procedures for forensic computing investigations that are able to effectively handle the presence of wireless devices and networks, and that there are forms of misuse that may escape detection by forensic investigation teams. This work was then developed into a taxonomy of wireless misuse. / Once the current state was known, this research sought to readdress the current state of forensic computing teams, through analysing the need for software tools and procedural changes to counter the misuses that this technology allows. Once software outcomes were developed, the legal and technical feasibility of their use was ascertained. Based on the outcomes of this work, a final set of software requirements was developed and the proposed methodology for their development was discussed. / A new series of procedures was also developed for forensic investigators to identify, contain and analyse sources of electronic evidence with 802.11-networking. Much of this work was based upon but extending current procedural guides for law enforcement. / The final outcome of this research was the development of a series of recommendations for forensic teams and research that incorporates short, medium and long term development for forensic teams as well as research and development. This work intended to provide mechanisms for future research that are jurisdictionally independent able to be adapted for each individual forensic team. The short term recommendations were primarily changes to procedure, whereas the medium and long terms changes sought to address the larger issues raised by wireless networking devices being the target of or involved in crime or misuse. / Much of this dissertation is exploratory in nature and much of its length is devoted to determining the current state of the misuse and current mechanisms employed to counter it. In such a rapidly developing field of study, this work will need constant revision as new technologies emerge and new forms of misuse take advantage of them. / Thesis (PhDInformationTechnology)--University of South Australia, 2007
