Vi lever i en snabbt utvecklande teknologisk värld och mängden internet-uppkopplade enheter ökar hastigt. År 2025 förväntas mängden IoT-enheter öka till 41.6 miljarder. En generell säkerhetsbrist bland dessa enheter har medfört att de blivit favoriserade mål och medel för nätverksattacker. Syftet med denna rapport är att undersöka kunskapen hos privatpersoner gällande säkerhet i IoT-enheter, vilka åtgärder de tagit för att säkra sina hemnätverk samt var de anser ansvaret ligga när det kommer till säkerhet i de enheter de köper. Rapporten undersöker även återförsäljares kunskap när det gäller säkerhet i IoT-enheter, tillverkares synpunkt samt vad lagen säger gällande ansvarsskyldighet. I vår undersökning fann vi att kunskapen om säkerhet och åtgärder för säkerhet är bristfällig. Samtidigt så finns ett stort förtroende till tillverkare att säkerheten i IoT-enheter på marknaden har en tillräckligt god implementerad säkerhet. Denna rapport visar att detta inte alltid är sant. Säkerhet kommer ofta i andra hand vid tillverkning och en stor efterfrågan har påskyndat utvecklingsarbetet av IoT-enheter vilket har skadat säkerhetstänket. Ett stort problem är användandet av fabriksinställda användarnamn och lösenord utan krav på konsumenten att åtgärda detta vid uppstart av en ny enhet. Dessa enheter blir lättåtkomliga offer för cyberattacker och möjligheterna för angripare växer hastigt. Krav måste ställas på tillverkare att hålla en minimum standard av säkerhetsimplementation och IoT som begrepp måste definieras med tydliga riktlinjer om vilka enheter som omfattas av begreppet. Svenska lagar som omfattar nätverksattacker är bristfälliga och reflekterar inte de möjligheter som finns idag för angripare. Fler funktioner i privatpersoners hem blir uppkopplade och kan manipuleras på nya sätt men det finns inga tydliga lagar som reflekterar detta problem.

Creating visualizations for Internet of Things (IoT) data can be a challenge due to the uncertain and voluminous nature of this type of data. Many different tools have been made to visualize voluminous data. One such tool is Amazon Web Service (AWS) Quicksight. Quicksight is marketed as a scalable system for big data. For IoT developers, the visualization task is only a smaller subtask, which is often not the focus for the developer. Therefore it is in the developer’s best interest to use an easy tool for visualizing their data. To study if Quicksight is a viable tool for developers of IoT systems a user study was executed. Both the perceived usability and measured understanding when using the system were studied. This was done by using the System Usability Scale (SUS) for the perceived usability. For measured understanding some questions regarding trends and errors were asked and a statistical classification was made. The study showed a tendency for the users to rely too much on the visual structure Autograph as well as their difficulty to extract information from aggregated visualizations. In addition it was cumbersome to connect data between different datasets. / Att skapa visualiseringar för IoT data kan vara utmanande på Internet of Things (IoTs) oförutsägbara och voluminösa natur. Det finns många olika verktyg för att visualisera data. Ett sådant verktyg är Amazon Web Service (AWS) Quicksight. Quicksight marknadsförs som ett skalbart system för big data. För IoT utvecklare är dock visualisering oftast en mindre deluppgift som inte ligger i fokus. Därför är det viktigt för utvecklare att använda ett lättanvänt verktyg för att visualisera data. För att undersöka ifall Quicksight är ett bra alternativ som verktyg för utvecklare av IoT system så utfördes en användarstudie. Både den uppfattade och uppmätt förståelsen av systemet studerades. System Usability Scale (SUS) användes för att mäta den uppfattade användbarheten. För att mäta den uppmätta förståelsen ställdes frågor om trender och fel i data som sedan delades in i statistisk klassificering. Studien visade att användare tenderar att förlita sig för mycket på den visuella strukturen Autograph samt att dem hade svårigheter att utvinna information från aggregerad visualisering. Därtill ansåg användarna att det var besvärligt att koppla samman flera dataset i en visualisering.

Cybersecurity is currently an important and relevant issue, as more and more industries are taking advantage of the accessibility of storing information online. To create a secure system one must know the potential risks and attacks on that system, making risk analysis a very potent tool. In this study, we performed such an analysis using the risk analysis method OCTAVE Allegro on a company providing a cloud-based service to find out what risks a cloud service provider might be exposed to, and the usefulness of said risk analysis method in this circumstance. We found that OCTAVE Allegro is suitable to use on smaller companies and applicable to cloud services, and the most severe risks identified were connected to leakage of client data with a consequence of damaging the company's reputation. Common areas of concern for these risks were third parties hacking the cloud server or other company systems to gain access to sensitive information. Such risks will likely be found at any company providing a cloud service that manages sensitive data, increasing the importance of risk analysis at these companies.

With the increase of devices on the internet that comes coupled with the growing IoT field, there is a high amount of research being conducted on the topic. Whilst much has been done to make these systems more scalable and resilient by replacing the current standard architecture with a decentralized one, the applied models mostly focus on the implementation details of such a system, and little thought is placed on the algorithms used to structure the architecture itself. Instead, one of the many, already defined protocols is used, and the system is built around this. These protocols, whilst elegant and outright ingenious in their own nature are initially intended for other applications, and hence do not take any advantage of the domain specifics of IoT, and hence the implemented solutions are sub-optimal in terms of performance and overhead. This thesis attempts to bridge that gap by first providing data on an existing IoT system, and then using the data to leverage the modifications of the prevailing protocol for decentralized peer-to-peer architectures. This is done by introducing groups in the ID scheme of the system, and thus greatly modifying the internal structure, forcing devices with interest in each other to be placed closely in the structure. The consequence of this is that there is a major reduction of overhead in searching for devices, bringing the total number of devices required to be contacted for normal use-cases down substantially.

Activities of daily living (ADLs) are everyday routine tasks which provide insight into the physical and cognitive wellbeing of older adults. ADLs are commonly self-reported to clinicians, which can lead to overestimation and underestimation of a patients’ functional abilities. Remote health monitoring is an emerging field aimed at utilizing technology for monitoring ADLs remotely, improving clinical accuracy and enabling older adults to age safely within their homes. In this dissertation, we report a Smart Home platform and two indoor positioning systems (IPSs) – (i) a hybrid Bluetooth Low Energy (BLE) and radar motion sensor system and (ii) a hybrid radio-frequency identification (RFID) and infrared (IR) range-finding system for tracking occupant mobility, the primary predictor of falls among older adults. For the Smart Home platform, the design methodology and technological features were explained. As for the IPSs’, position accuracy of multiple occupants within multiple rooms of a residential apartment was evaluated. The systems were also evaluated for cost, implementation ease, and scalability, which, upon reviewing literature, were identified as key metrics for developing an IPS for enabling aging in place. Both IPSs enforced a decentralized localization architecture and performed well, achieving high localization accuracy for multiple occupants. / Thesis / Master of Applied Science (MASc) / By 2031, the number of people aged 65 and over is expected to nearly double. This population shift is concerning for healthcare providers as limited resources become increasingly constrained. Resultantly, older adults, the largest consumers of healthcare, face longer wait times and reduced quality of care. Remote health monitoring is an emerging field aimed at utilizing technology for monitoring older adults within their homes. In this thesis, we report a Smart Home platform and two indoor positioning systems (IPSs) for tracking resident mobility, the primary predictor of falls among older adults. For the Smart Home platform, the design methodology and technological features were explained. As for the IPSs’, position accuracy of multiple occupants within multiple rooms of a residential apartment was evaluated. Upon reviewing literature system cost, implementation ease, and scalability, were identified as key metrics for developing an IPS for enabling aging in place. Both IPSs performed well, achieving high localization accuracy for multiple occupants.

Yes / Event monitoring is an essential application of Smart City platforms. Real-time monitoring of gully and drainage blockage is an important part of flood monitoring applications. Building viable IoT sensors for detecting blockage is a complex task due to the limitations of deploying such sensors in situ. Image classification with deep learning is a potential alternative solution. However, there are no image datasets of gullies and drainages. We were faced with such challenges as part of developing a flood monitoring application in a European Union-funded project. To address these issues, we propose a novel image classification approach based on deep learning with an IoT-enabled camera to monitor gullies and drainages. This approach utilises deep learning to develop an effective image classification model to classify blockage images into different class labels based on the severity. In order to handle the complexity of video-based images, and subsequent poor classification accuracy of the model, we have carried out experiments with the removal of image edges by applying image cropping. The process of cropping in our proposed experimentation is aimed to concentrate only on the regions of interest within images, hence leaving out some proportion of image edges. An image dataset from crowd-sourced publicly accessible images has been curated to train and test the proposed model. For validation, model accuracies were compared considering model with and without image cropping. The cropping-based image classification showed improvement in the classification accuracy. This paper outlines the lessons from our experimentation that have a wider impact on many similar use cases involving IoT-based cameras as part of smart city event monitoring platforms. / European Regional Development Fund Interreg project Smart Cities and Open Data REuse (SCORE).

Yes / The exponential growth of the Internet of Things (IoT) has paved the way for safety-critical cyber-physical systems to enter our everyday activities. While such systems have changed the way of our life, they brought new challenges that can adversely affect our life and the environment. Safety and security are two such challenges that can hamper the widespread adoption of new IoT applications. Due to a large number of connected devices and their ability to control critical physical assets, intended attacks on them and/or unintended failure events such as mechanical failure of devices, communication failure and unforeseen bad interactions between connected devices may cause an IoT-based system to enter into unsafe and dangerous physical states. By considering the importance of safety and security of IoT systems, in this article, we present a security-enabled safety monitoring framework for IoT-based systems. In the proposed framework, we utilise design-time system analysis to create an executable monitoring model that enables run-time safety assurance provision for a system via collecting and analysing operational data and evidence to determine the safety status of the system and then taking appropriate actions and securely communicating the safety status and recommended actions to the system users to minimise the risk of the system entering into an unsafe state.
