Security Mechanisms for Connectivity of Smart Devices in the Internet of Things

The Internet of Things, abbreviated as IoT, is one of the most hyped concepts in this post-personal computer (PC) era. Gartner’s information technology Hype Cycle also gives much importance to the Internet of Things because of its immense opportunities in emerging global markets now and in forthcoming years. In the IoT, the base is a smart device which may be a smartphone, a tablet, a laptop, a Sony smart wallet, or a sensory device. The Internet of Things pervades almost all kinds of physical “things,” whether processing devices, devices with embedded processing ability, or measuring sensory devices. This technology provides a platform in which the physical world can be coupled with the virtual world, with the ultimate aim of a better quality of life. Nevertheless, IoT communication and connectivity are facing several security issues. The objective of the research, presented in this chapter, is to explore the concept of smart devices from the viewpoint of scholars, academicians, practitioners, and developers. Furthermore, this chapter also discusses, in some detail, the security mechanisms of smart devices, with emphasis on both physical and logical remedy mechanisms.

Understanding cloud computing adoption: A model comparison approach

The purpose of this paper is to understand cloud computing adoption. Specifically, this paper aims to compare two theoretical models and an integrated model to identify which theoretical models best predicts cloud computing adoption. An empirical study was conducted through an survey from 280 companies in IT, manufacturing and finance sectors in India. The data was analysed using exploratory and confirmatory factor analyses. Further, structural equation modeling using AMOS 20.0 was used to test the proposed model. Results show that the integrated mediating TAM-TOE and Direct TAM- TOE model have greater explanatory power of cloud computing adoption intention than the technology acceptance model (TAM) and technological organisational environmental framework (TOE). Mediating TAM-TOE provides more complete understanding of adoption intention and Direct TAM-TOE provides the generic cognition of understanding adoption intention and determinants of managerial decision making. Thus, the Mediating TAM-TOE is a preferable model. Security concern and Third party control are salient factors influencing cloud computing adoption intention through perceived usefulness (PU) and perceived ease of use (PU).This study is one of the first studies to examine of influence change of variables and compare the relative ability of two competing theories, TAM and TOE, and an integrated model in explaining cloud computing adoption intention.

Developing a Cloud-Computing Adoption Framework

This article aims to propose an extended technology acceptance model–technical–organization– environment (TAM–TOE) framework and to develop its measures for cloud-computing adoption in organizations. Information technology adoption literature based on the TAM model and the TOE framework was reviewed to identify a set of variables relevant to cloud computing adoption. A conceptual framework was developed to integrate the TAM model and the TOE framework. Further, cloud-specific variables (security and third-party control) were also incorporated in the framework. This extended TAM–TOE framework was qualitatively analyzed using an interview method which resulted in 12 of the variables relevant to cloud-computing adoption. Further, a questionnaire was designed, pre-tested and surveyed to develop reliable measures of cloud-computing adoption. It resulted in conceptualizing an extended TAM–TOE framework for cloud-computing adoption and in developing its reliable measures. This study has a smaller sample size and is limited to cloud-computing adoption. On the other hand, it contributes towards the cloud-computing adoption literature. Managers can use measures identified to analyze their suitability for implementing cloud computing in their organizations. This article has a strong contribution in integrating the TAM model and the TOE framework, and developing measures for cloud-computing adoption.

Critical Factors of Cloud Computing Adoption in Organizations: An Empirical Study:

Using extended Technology Acceptance Model (TAM), this study attempts to assess empirically crucial factors affecting cloud computing adoption intentions. It explores security, availability and compliance-related challenges in cloud computing and makes the necessary recommendation which can help to mitigate the risk in cloud computing. A framework was developed to test the effect of security, availability of cloud service provider and compliance-related factors on cloud computing adoption intentions mediated by perceived ease of use (PEOU) and perceived usefulness (PU). A questionnaire for the factors was developed to collect the data from 280 companies in information technology, manufacturing and finance sectors in India. The data was analyzed using exploratory and confirmatory factor analyses. Further, structural equation modelling using AMOS 20.0 was used to test the proposed model. The empirical results show that cloud computing adoption intention is determined by PU and PEOU. Further, PU is found to be significantly influenced by PEOU. Risk as well as availability and support are found to be significant on PEOU. In addition, threat, risk, vulnerability and compliance are found to be significant on PU. The model can be used as a guideline to ensure a positive outcome of the cloud computing adoption in organizations. The findings offer cloud computing users with a better understanding of how security, availability of cloud service provider and compliance-related factors affect cloud computing adoption intentions. It also provides relevant recommendations to achieve conducive implementation environment for cloud computing adoption. This study is an attempt to explore and develop model for cloud computing adoption intentions that was theoretically grounded in the TAM.

Exploratory Study of Internet Banking Technology Adoption

Internet has brought significant impact on the way people conduct life in the present-day scenario. In this premise the Indian economy has experienced rapid growth over the last decade, developing Internet Banking Technology IBT for transforming the traditional lines of banking. This shift has brought profound challenges and opportunities to both bank and its customers. Customers have found in IBT a new ease to do the financial transaction. Review of these literatures indicates that there are not many studies on IBT Adoption in Indian scenario. The review shows that existing study on IBT adoption in Indian context has shown little evidence of an integrated model for IBT Adoption. This indicates that a comprehensive research in the area of IBT adoption under Indian context is very much limited. This research attempts to analyse existing technology adoption theories for formulating an integrated framework to investigate the factors of IBT adoption in India.

KM capability for software development: a case study of the Indian software firms

Organisational knowledge management (KM) capability is developed to allow companies to share, create and disseminate their organisational knowledge resources. The paradigm shift from traditional business to information communication technology (ICT) enabled business, brought fundamental changes in business environment. Rapidly changing technology is a key feature of software industry and it may be easier for organisations to manage these changes if they develop their KM capability. However, this is not easy since most organisations in the Indian software industry compete for the same customers with knowledge worker from the same pool. In this paper, a generic model of a KM capability is proposed. This framework is used to analyse the KM capability in Indian software firms. The case study illustrates and highlights the benefits and advantages of establishing a KM capability. The results from the case study showed that KM capability is an imperative for software development. The study also suggests few recommendations that may be used to guide the development of KM capability elsewhere. This studys limitations and suggestions for future research are also discussed.

Quality of Life @ Palava Smart City: A Case Study

Quality of Life (QoL) is the new buzzword in every corner of the world. Though the concept of QoL has been in existence since decades in association with human lifestyle, it has now crept into every urban citizen’s life. QoL is multidimensional and depends on the level of basic need fulfilment, security requirements, socialization and psychosocial factors. Moreover, QoL is both an individual and collective attribute. Besides, for ensuring QoL in cities, a large number of Internet of Things (IoT) technologies need to be deployed. This article articulates that in these days, QoL can be met in the upcoming Smart Cities, and substantiates it with reporting the QoL practices in Palava Smart City (Mumbai). Since ‘Smart Cities’ is a new notion, an exploratory study has been conducted. The primary data collection techniques are surveys, in-depth interviews and observation. In addition, data have been gathered from secondary sources including various published articles, corporate white papers, blogs and videos. The data analysis has been carried out by SPSS and Atlas-ti software. Palava City Management Association (PCMA) has been planning and implementing high-tech infrastructure, socialization amenities, healthcare benefits, citizen security and embedding IoT technologies for ensuring round-the-clock operational efficiency in the city premises. Authors report that Palava Smart City will soon become one of the top-most liveable cities in the world.
