Guest Editorial Special Issue on: Big Data Analytics in Intelligent Systems

The amount of information that is being created, every day, is quickly growing. As such, it is now more common than ever to deal with extremely large datasets. As systems develop and become more intelligent and adaptive, analysing their behaviour is a challenge. The heterogeneity, volume and speed of data generation are increasing rapidly. This is further exacerbated by the use of wireless networks, sensors, smartphones and the Internet. Such systems are capable of generating a phenomenal amount of information and the need to analyse their behaviour, to detect security anomalies or predict future demands for example, is becoming harder. Furthermore, securing such systems is a challenge. As threats evolve, so should security measures develop and adopt increasingly intelligent security techniques. Adaptive systems must be employed and existing methods built upon to provide well-structured defence in depth. Despite the clear need to develop effective protection methods, the task is a difficult one, as there are significant weaknesses in the existing security currently in place. Consequently, this special issue of the Journal of Computer Sciences and Applications discusses big data analytics in intelligent systems. The specific topics of discussion include the Internet of Things, Web Services, Cloud Computing, Security and Interconnected Systems

Guest editorial: technology mobility

This special issue of Journal of Information, Communication & Ethics in Society entitled Technology Mobility, comprises seven papers that provide cutting edge information and knowledge of ethics, ICT knowledge, e-government services, social media and security. The guest editors invited the first paper, selected papers 2–5 from the IADIS 9th International Conference on Internet Technologies & Society 2019 and 6th International Conference on Educational Technologies 2019 which was held in Hong Kong, and included the two last papers, originally submitted to the regular issue, owing to their adequacy to the topics of this special issue. The papers from the conferences have been extended significantly and peer-reviewed further to achieve a final high publication standard.info:eu-repo/semantics/publishedVersio

The Conundrum of Security in Modern Cloud Computing

In today’s economic climate organizations are seeking greater cost-saving measures, increased agility, and scalability that responds to the rapid changes in technology and business. Cloud computing, with its low cost pay-as-you-go business model, is helping organizations manage these changes while transforming information technology (IT) into an engine that drives business. Benefits from on-demand clouds provide users greater portability and the ability to access information from virtually anywhere: at home, a client location, when traveling, or at the office. The reduced costs and increased flexibility, however, associated with cloud computing also come with complex security issues and increased overall risk. When cloud services are moved beyond organizational boundaries, outside the border firewall, security is heightened for most organizations and navigating the complexity of these environments can be daunting. In this research paper we seek to help organizations make pragmatic decisions about where and when to use cloud solutions by outlining specific security issues that enterprises should address. We use external research sources and explore current security trends within cloud computing in order to provide background information, related research, and conclusions. We make use of colleagues, textbooks, peer reviewed journal articles, and Internet websites related to information technology and information security. Each section of our research is formatted similarly and presents pertinent security information, techniques, and tools that organizations would need in order to make relevant decisions when utilizing Software as a Service (SaaS), Platform as a Service (PaaS), or Infrastructure as a Service (IaaS)

Information integration platform for patient-centric healthcare services: design, prototype and dependability aspects

Published version of an article in the journal: Future Internet. Also available from the publisher at: http://dx.doi.org/10.3390/fi6010126 Open AccessTechnology innovations have pushed today’s healthcare sector to an unprecedented new level. Various portable and wearable medical and fitness devices are being sold in the consumer market to provide the self-empowerment of a healthier lifestyle to society. Many vendors provide additional cloud-based services for devices they manufacture, enabling the users to visualize, store and share the gathered information through the Internet. However, most of these services are integrated with the devices in a closed “silo” manner, where the devices can only be used with the provided services. To tackle this issue, an information integration platform (IIP) has been developed to support communications between devices and Internet-based services in an event-driven fashion by adopting service-oriented architecture (SOA) principles and a publish/subscribe messaging pattern. It follows the “Internet of Things” (IoT) idea of connecting everyday objects to various networks and to enable the dissemination of the gathered information to the global information space through the Internet. A patient-centric healthcare service environment is chosen as the target scenario for the deployment of the platform, as this is a domain where IoT can have a direct positive impact on quality of life enhancement. This paper describes the developed platform, with emphasis on dependability aspects, including availability, scalability and security
