Security Evaluation of Cyber-Physical Systems in Society- Critical Internet of Things
In this paper, we present evaluation of security
awareness of developers and users of cyber-physical systems. Our
study includes interviews, workshops, surveys and one practical
evaluation. We conducted 15 interviews and conducted survey with
55 respondents coming primarily from industry. Furthermore, we
performed practical evaluation of current state of practice for a
society-critical application, a commercial vehicle, and reconfirmed
our findings discussing an attack vector for an off-line societycritical
facility. More work is necessary to increase usage of security
strategies, available methods, processes and standards. The security
information, currently often insufficient, should be provided in the
user manuals of products and services to protect system users. We
confirmed it lately when we conducted an additional survey of
users, with users feeling as left out in their quest for own security
and privacy. Finally, hardware-related security questions begin to
come up on the agenda, with a general increase of interest and
awareness of hardware contribution to the overall cyber-physical
security. At the end of this paper we discuss possible
countermeasures for dealing with threats in infrastructures,
highlighting the role of authorities in this quest
Fall Prediction and Prevention Systems: Recent Trends, Challenges, and Future Research Directions.
Fall prediction is a multifaceted problem that involves complex interactions between physiological, behavioral, and environmental factors. Existing fall detection and prediction systems mainly focus on physiological factors such as gait, vision, and cognition, and do not address the multifactorial nature of falls. In addition, these systems lack efficient user interfaces and feedback for preventing future falls. Recent advances in internet of things (IoT) and mobile technologies offer ample opportunities for integrating contextual information about patient behavior and environment along with physiological health data for predicting falls. This article reviews the state-of-the-art in fall detection and prediction systems. It also describes the challenges, limitations, and future directions in the design and implementation of effective fall prediction and prevention systems
