Cybercrime and Cyber-security Issues Associated with China: Some Economic and Institutional Considerations

China is linked to cybercrimes of diverse types, scales, motivations and objectives. The Chinese cyberspace thus provides an interesting setting for the study of cybercrimes. In this paper, we first develop typology, classification and characterization of cybercrimes associated with China, which would help us understand modus operandi, structures, profiles and personal characteristics of cybercrime organizations and potential perpetrators, the signature aspects and goals of cybercrimes, the nature and backgrounds of the criminal groups involved, characteristics of potential targets for criminal activities, the nature and extent of the damage inflicted on the victims and the implications to and responses elicited from various actors. We then examine this issue from developmental and international political economy angles. Specifically, we delineate salient features of China’s politics, culture, human capital and technological issues from the standpoint of cyber-security and analyze emerging international relations and international trade issues associated with this phenomenon. Our analysis indicates that China’s global ambition, the shift in the base of regime legitimacy from MarxLeninism to economic growth, the strong state and weak civil society explain the distinctive pattern of the country’s cyber-attack and cyber-security landscapes

Cyber-crime Science = Crime Science + Information Security

Cyber-crime Science is an emerging area of study aiming to prevent cyber-crime by combining security protection techniques from Information Security with empirical research methods used in Crime Science. Information security research has developed techniques for protecting the confidentiality, integrity, and availability of information assets but is less strong on the empirical study of the effectiveness of these techniques. Crime Science studies the effect of crime prevention techniques empirically in the real world, and proposes improvements to these techniques based on this. Combining both approaches, Cyber-crime Science transfers and further develops Information Security techniques to prevent cyber-crime, and empirically studies the effectiveness of these techniques in the real world. In this paper we review the main contributions of Crime Science as of today, illustrate its application to a typical Information Security problem, namely phishing, explore the interdisciplinary structure of Cyber-crime Science, and present an agenda for research in Cyber-crime Science in the form of a set of suggested research questions

The Professionalization of Hackers: A Content Analysis of 30 Years of Hacker Communication

Underground hacking has evolved from its early countercultural roots to become a complex and varied phenomenon. By combining a historical review of the literature with a content analysis of 30 years of underground hacker communication, we show that hacking has evolved in three waves to embrace learning and creativity, intrusion and crime, as well as politics and cyberwarfare. We uncover a paradoxical relationship between hackers and society at large where underground hacking is considered a digital crime while at the same time inspiring and driving corporate innovation, cybersecurity, and even cyberwarfare. The outcome of our research provides a nuanced picture of the hacker underground by highlighting differences between competing discursive themes across time. Moreover, by translating these themes into a set of six contrasting personas of IS professionals, we discuss how knowledge, technologies, and creative practices of underground hackers are being professionalized. We use this discussion to provide implications and a research agenda for IS studies in cybersecurity, innovation, and cyberwarfare

User Authentication and Supervision in Networked Systems

This thesis considers the problem of user authentication and supervision in networked systems. The issue of user authentication is one of on-going concern in modem IT systems with the increased use of computer systems to store and provide access to sensitive information resources. While the traditional username/password login combination can be used to protect access to resources (when used appropriately), users often compromise the security that these methods can provide. While alternative (and often more secure) systems are available, these alternatives usually require expensive hardware to be purchased and integrated into IT systems. Even if alternatives are available (and financially viable), they frequently require users to authenticate in an intrusive manner (e.g. forcing a user to use a biometric technique relying on fingerprint recognition). Assuming an acceptable form of authentication is available, this still does not address the problem of on-going confidence in the users’ identity - i.e. once the user has logged in at the beginning of a session, there is usually no further confirmation of the users' identity until they logout or lock the session in which they are operating. Hence there is a significant requirement to not only improve login authentication but to also introduce the concept of continuous user supervision. Before attempting to implement a solution to the problems outlined above, a range of currently available user authentication methods are identified and evaluated. This is followed by a survey conducted to evaluate user attitudes and opinions relating to login and continuous authentication. The results reinforce perceptions regarding the weaknesses of the traditional username/password combination, and suggest that alternative techniques can be acceptable. This provides justification for the work described in the latter part o f the thesis. A number of small-scale trials are conducted to investigate alternative authentication techniques, using ImagePIN's and associative/cognitive questions. While these techniques are of an intrusive nature, they offer potential improvements as either initial login authentication methods or, as a challenge during a session to confirm the identity of the logged-in user. A potential solution to the problem of continuous user authentication is presented through the design and implementation o f a system to monitor user activity throughout a logged-in session. The effectiveness of this system is evaluated through a series of trials investigating the use of keystroke analysis using digraph, trigraph and keyword-based metrics (with the latter two methods representing novel approaches to the analysis of keystroke data). The initial trials demonstrate the viability of these techniques, whereas later trials are used to demonstrate the potential for a composite approach. The final trial described in this thesis was conducted over a three-month period with 35 trial participants and resulted in over five million samples. Due to the scope, duration, and the volume of data collected, this trial provides a significant contribution to the domain, with the use of a composite analysis method representing entirely new work. The results of these trials show that the technique of keystroke analysis is one that can be effective for the majority of users. Finally, a prototype composite authentication and response system is presented, which demonstrates how transparent, non-intrusive, continuous user authentication can be achieved
