Recent developments in sensor technology, wearable computing, Internet of Things (IoT), and wireless communication have given rise to research in ubiquitous healthcare and remote monitoring of human’s health and activities. Health monitoring systems involve processing and analysis of data retrieved from smartphones, smart watches, smart bracelets, as well as various sensors and wearable devices. Such systems enable continuous monitoring of patients psychological and health conditions by sensing and transmitting measurements such as heart rate, electrocardiogram, body temperature, respiratory rate, chest sounds, or blood pressure. Pervasive healthcare, as a relevant application domain in this context, aims at revolutionizing the delivery of medical services through a medical assistive environment and facilitates the independent living of patients. In this chapter, we discuss (1) data collection, fusion, ownership and privacy issues; (2) models, technologies and solutions for medical data processing and analysis; (3) big medical data analytics for remote health monitoring; (4) research challenges and opportunities in medical data analytics; (5) examples of case studies and practical solutions.

With the emergence of the Internet, the volume of cyberattacks has been progressively growing and, therefore, adequate security of information has a crucial role in IT systems. Organisations face complex decisions regarding the selection of security controls that allow protecting their information assets. The implementation of these controls should ensure an adequate level of protection. However, their selection requires knowledge about the vulnerabilities and threats existing in the organisation, and the investment in security must comply with economic constraints. This work proposes a framework to support an organisation to identify security vulnerabilities and optimise a portfolio of security controls to mitigate them. Those security controls may be of a mixed nature, such as hardware controls, software controls, policies, procedures and training actions. The framework is established using the standards ISO/IEC 27001:2013 and ISO/IEC 27002:2013 to support the identification of vulnerabilities/threats and the choice of controls that can mitigate them. Once the existing vulnerabilities/threats are identified, one has to select the subset of controls to implement, assuring an adequate mitigation at the lowest cost. An integer programming model is used to address this optimisation problem within the framework, which has been implemented as a prototype decision support tool.
