Threat Modelling

The emergence of ecommerce almost three decades ago has completely transformed the approach to purchasing goods and services across various countries in the world. Almost every country in the globe, now have some form of ecommerce operations, this has further been enhanced by the stay at home COVID-19 induced lockdowns. The value and volume of transactions has also increased in transactions. However, there has been security concerns impacting ecommerce operations, which has in part, led to increasing adoption of hosting ecommerce systems in the public cloud. Threat modelling offer mechanisms to enhance the security of information technology (IT) systems. In this paper, we apply different threat modelling techniques to decompose the migration of an on-premise hosted ecommerce system to the public cloud and also evaluate these threat modelling techniques.

Business Requirements

Technological infrastructure must satisfy business requirements, and more importantly, it must be able to evolve to meet the new requirements. This requires not only a good understanding of business strategies, visions and functions, but also the evolvability built into the architecture. This chapter first presents a semiotic approach to the business and information technology (hereafter IT) systems. This approach treats the IT system as an integral part of the business organisation. The chapter then discusses the applicability of a semiotic framework in the e-government in the UK, particularly in an evolvable architecture for e-policing. The semiotic framework is applied in the assessment of the e-government strategies and systems requirements, and in the analysis of these requirements to the e-architecture. A case study demonstrating the applicability of the framework is conducted to evaluate the implementation of the national Information Systems Strategy for the Police Service (ISS4PS) and the Crime Justice Information Technology community (CJIT) in the UK.

Access Services

This chapter explains how austerity has led to an increasingly fragmented and disparate economy and geography of welfare. These changes have affected people's ability to access services, leaving some of them isolated and excluded from activities that they previously enjoyed. The chapter then questions the use of new information technology (IT) systems and the related expansion of cybernetic relations to register, administer, manage, and target some of the most vulnerable members of society. It argues that these virtual systems emerge as a way of dealing with cases that need physical and in-depth contact in the context of austerity budgets rather than a tested way of pooling information to save lives. This argument suggests that they can also be a way to exclude service users from decision-making about their entitlement and ultimately their lives, reconfiguring the power relations between the public and the state.

Cloud services and technologies are currently receiving increased attention from the industry mostly due to business-driven promises and expectations. Significant innovations in virtualization and distributed computing, as well as improved access to high-speed Internet and a weak economy, have accelerated interest in cloud computing. However, is the migration to the Cloud the most profitable option for every business? Enterprise adoption of cloud computing often requires a significant transformation of existing Information Technology (IT) systems and processes. To justify such a change, a viable business case must be made based on the economics of transformation. This chapter presents a study of the basic parameters for estimating the potential infrastructure and software costs deriving from building and deploying applications on cloud and on-premise assets. Estimated user demand and desired quality attributes related to an application are also addressed in this chapter as they are aspects of the decision problem that also influence the choice between cloud and in-house solutions.

Boolean Expressions

Boolean algebra, minimization of Boolean expressions, and logic gates are often included as subjects in electronics, computer science, information technology, and engineering courses as computer hardware and digital systems are a fundamental component of IT systems today. We believe that students learn minimization of Boolean expressions better if they are given interactive practical learning activities that illustrate theoretical concepts. This chapter describes the development and use of a software tool (named LOGIC-Minimiser) as an aid to enhance teaching and learning minimization of Boolean expressions.

Global Information Systems

Managers, IT practitioners, and IS researchers are easily seduced by the latest information technology wave. Consequently, we tend not to question conventional assumptions about the implementation of IT systems in organizations. Instead of providing managers with directions, IS researchers can sometimes turn into prognosticators of the latest information technology fad. We call on researchers to delve below the surface of new IT trends to expose inconsistencies between technological promises and the reality of deploying information systems in global organizations. Many IS researchers are turning their attention to the area of global information management (Gallupe and Tan, 1999). This journal is a vehicle for publishing such research work. Interest in integrated global information systems is fueled both by the developments in information and communications technologies and the trends in business towards globalization of products and markets. Conventional wisdom suggests that businesses operating in global markets would benefit from implementing global information systems and achieve economies of scale and scope. This may be true in some cases, but does it hold for all cases? I suggest it may not. In certain cases deploying global IT systems could lead to diseconomies of scale.

The main aim of the article was to estimate select aspects of knowledge management quality evaluations in contemporary enterprises from theoretical and practical perspectives. Measuring knowledge management is the biggest challenge for both theoreticians and practitioners. The survey was addressed to organizations conducting business activity in Poland. The research was carried out in 2019 in the form of an online survey. For international organizations, the survey was intended for representatives of these companies’ local branches. It has been shown that the factors that most strongly affect the quality of knowledge are directly related to infrastructure and information technology systems (IT systems). The article contributes to managerial practice by pointing out the importance of evaluating knowledge management quality from the process perspective. The article’s originality lies in the contribution to the literature of evaluating knowledge management quality by empirically analyzing it in contemporary enterprises. The results of research in the field involving assessing the quality of knowledge management have shown the need to focus not only on information technology tools (IT tools) related to infrastructure, but also on the processes approach, taking into account the priority role of the employees.

Management Issues

The growing power of computer-telephony integration (CTI) systems is encouraging many companies to create call centres. These deal with a growing range of business processes and, in doing so, can be used to challenge established organizational arrangements. The range of human and management issues that need to be dealt with has yet to become clear. Some insights into these are offered from a study of one call centre over 2 years, from shortly before its physical introduction to the present day. These empirical observations are set within the wider literature on organizational change and information technology (IT), particularly the processual and integrationist perspectives. The paper uses the evidence of the case to elaborate the integrationist model so that it reflects the areas of human action more fully. It concludes by outlining the implications of this perspective for managers seeking to build effective call centres or other forms of interorganizational IT system.

Organizational Requirements

Traditional methods of systems design have tended to concentrate on capturing functional requirements and from them develop a system that will provide users with a technical solution to a problem they may have. However, there is a growing understanding, with historical origins in sociotechnical systems theory, that technical solutions alone, regardless of how well designed, may not succeed fully unless there is a concomitant understanding of the organization into which the technical solution is to be introduced. Organizational requirements, therefore, should become considerations of equal importance to systems designers. The ESPRIT Project ORDIT (organizational requirements definition for information technology) has developed a methodology which identifies and operationalizes organizational requirements for IT systems. This paper presents a case study in which the ORDIT concepts are applied to the process of introducing an IT system into a courtroom.
