Abstract: This paper aims to examine the challenges of preventing internal identity theft related crimes (IIDTRC) in the UK retail sector. Using an in-depth multiple case studies of a selected number of cross-functional management teams in the UK retail companies, management roles were analysed. We used semi-structured interview as a qualitative data collection technique and used Nvivo aided thematic analysis and interpretivism underpinned by Role-Based Framework (RBF) for analysis. Our findings revealed that vagueness of roles and lack of clarity in sharing data security responsibilities are the major challenges of preventing IIDTRC in UK retail companies. We suggest an application of RBF which provides a conceptual analysis for cross-functional management team to address the challenges of preventing IIDTRC. RBF enables clarity of shared roles where both information security and crimes prevention teams work in unison is required to prevent IIDTRC to maximise internal data security. Contributions for policymakers are offered in this paper. Collapse

Abstract: In this paper, we analyze the impact of various factors on meeting service level agreements (SLAs) for information technology (IT) incident resolution. Using a large IT services incident dataset, we develop and compare multiple models to predict the value of a target Boolean variable indicating whether an incident met its SLA. Logistic regression and neural network models are found to have the best performance in terms of misclassification rates and average squared error. From the best-performing models, we identify a set of key variables that influence the achievement of SLAs. Based on model insights, we provide a thorough discussion of IT process management implications. We suggest several strategies that can be adopted by incident management teams to improve the quality and effectiveness of incident management processes, and recommend avenues for future research.

Abstract: 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. Collapse

Abstract: Fueled by increasing data availability and the rise of technological advances for data processing and communication, business analytics is a key driver for smart manufacturing. However, due to the multitude of different local advances as well as its multidisciplinary complexity, both researchers and practitioners struggle to keep track of the progress and acquire new knowledge within the field, as there is a lack of a holistic conceptualization. To address this issue, we performed an extensive structured literature review, yielding 904 relevant hits, to develop a quadripartite taxonomy as well as to derive archetypes of business analytics in smart manufacturing. The taxonomy comprises the following meta-characteristics: application domain, orientation as the objective of the analysis, data origins, and analysis techniques. Collectively, they comprise eight dimensions with a total of 52 distinct characteristics. Using a cluster analysis, we found six archetypes that represent a synthesis of existing knowledge on planning, maintenance (reactive, offline, and online predictive), monitoring, and quality management. A temporal analysis highlights the push beyond predictive approaches and confirms that deep learning already dominates novel applications. Our results constitute an entry point to the field but can also serve as a reference work and a guide with which to assess the adequacy of one's own instruments. Collapse

Abstract: As blockchain development continues at an ever-increasing pace, an increasing number of individual actors and organizations throughout entire economies get into contact with the technology. Furthermore, the growing collaboration of companies, customers, suppliers, and other actors is evolving into a multilateral network between the parties engaged with the technology. Therefore, to understand blockchain-based business models and innovations, it is necessary to understand human interactions within blockchain ecosystems. Consequently, this paper offers new insights concerning the role of human actors within blockchain ecosystems. For this purpose, the structure within and around the Ethereumblockchain is analyzed using existing literature on the Ethereum ecosystem and Sociotechnical systems. The analysis results are then placed in their context and summarized in a framework for comparable ecosystems. Collapse

Abstract: Cyber Attacks have been on an increase in the past decade. Dominant academic research has considered a range of theoretical approaches to the study of cyberattacks on organizations and society at large. However, there is a paucity of research that systematically reviews the current literature to define current emphasis and propose future research directions. In this paper we use the Latent Dirichlet Allocation approach to review cyberattack research in the Chartered Association of Business Schools level 3 and above journals over the last two decades. In a final synthesis we propose a future research agenda. Collapse

Abstract: Effective cybersecurity education is a critical domain in addressing the shortage of the cybersecurity workforce. To prepare students for real-world workforce challenges, hands-on practice is an important component in cybersecurity education. We integrated gamification into hands-on cybersecurity practice and conducted an empirical study on how gamification impacts students' learning outcome and career interests. Questionnaire data have been collected and will be analyzed to test our hypotheses. The expected results will address the impact of gamification on learning outcomes and suggest how gamification can be most effectively applied to cybersecurity education. Collapse

Abstract: Principles required for secure electronic voting using the Internet are known and published. Although the Internet voting functionalities and technologies are well-defined, none of the existing state-sponsored Internet voting approaches in use incorporate a total Internet-based system approach that includes voter registration, the voting process, and vote counting. The distributed Internet voting architecture concept discussed in this article uses a novel thin client approach to Internet voting. The architecture uses existing technologies and knowledge to create a viable whole system approach to Internet voting. This article describes various aspects and processes necessary to support an integrated approach. The application programming interface software for many of the critical functions was developed in Python and functionality tested. A virtual network, including a cloud-based functionality, was created and used to evaluate the various conceptual aspects of the proposed architecture. This included the concepts associated with programming and accessing smart cards, capturing and saving fingerprint data, structuring virtual private networks using tunneling and Internet Protocol Security, encrypting ballots using asymmetric encryption, using symmetric encryption for secret cookies, thin client interaction, and creating hash functions to be used within a blockchain structure in a Merkle tree architecture. The systems’ primary user targets are individuals remotely located from their home voting precincts and senior citizens who have limited mobility and mostly reside in assisted living facilities. The research supports the contention that a cybersecure Internet voting system that significantly reduces the opportunity for mail-in voter fraud, helps to ensure privacy for the voter, including nonrepudiation, nonattribution, receipt freeness, and vote acknowledgment can be created using existing technology.

Abstract: Emerging paradigms of attack challenge enterprise cybersecurity with sophisticated custom-built tools, unpre­ dictable patterns of exploitation, and an increasing ability to adapt to cyber defenses. As a result, organizations continue to experience incidents and suffer losses. The responsibility to respond to cybersecurity incidents lies with the incident response (IR) function. We argue that (1) organizations must develop ‘agility’ in their IR process to respond swiftly and efficiently to sophisticated and potent cyber threats, and (2) Real-time analytics (RTA) gives organizations a unique opportunity to drive their IR process in an agile manner by detecting cybersecurity incidents quickly and responding to them proactively. To better understand how organizations can use RTA to enable IR agility, we analyzed in-depth data from twenty expert interviews using a contingent resource-based view. The results informed a framework explaining how organizations enable agile characteristics (swiftness, flexibility, and innovation) in the IR process using the key features of the RTA capability (complex event processing, decision automation, and on-demand and continuous data analysis) to detect and respond to cybersecurity incidents as-they-occur which, in turn, improves their overall enterprise cybersecurity performance.
