The goal of the thesis is to provide investors and established businesses insights into the evolving concept of Internet of Things in the context of a business opportunity. First, the thesis provides comprehensive overview of the IoT concept, its historical development and relevant concepts similar to IoT including its definition and explanation. Second, the thesis discusses IoT as a disruptive technology with implications for general business strategy, current business models, value chains and competitive landscape. Third, it describes overwhelming opportunities for IoT application in various business fields and processes bringing added value to its stakeholders. Visionary concepts and applicable use cases are identified. Finally, the thesis analyses IoT market perception from both customer and business perspective based on quantitative and qualitative data researched. The research is focused mainly on customer awareness and value perception of IoT products as well as major drivers and challenges of the IoT market from business players' perspective. Such analytical insights identify major patterns and dynamism of the IoT market.

The presence of smart wearables has established itself as a norm of the 21 st century, but the state of their trustworthiness from the viewpoint of personal safety remains debatable. The information gathered by such devices has great potential for personal safety risks and must be handled safely. Previous work on the Garmin Venu watch gave room for relevant future work. This thesis aims to perform further evaluation of this smartwatch in unexplored areas. The work took inspiration from the relatively new “PatrIoT” penetration testing methodology, developed in-house at the Network and Systems Engineering lab, customized for penetration testing of Internet of Things devices. This project examined a broad surface on the watch including network traffic, data over USB connection, a few details in the watch’s update mechanism, probed for some memory attack mitigations, fuzz testing of some functions in the Software Development Kit’s Application Programming Interface, and some more. According to these investigations, the watch is perceived as safe. A deeper look into some investigations is left for future work. / Bärbara enheter har blivit en normal del av 21:a århundradet, men deras pålitlighet från ett personligt säkerhetssynvinkel är diskutabelt. Informationen som samlas in av dessa har stort potential för att orsaka personliga säkerhetsrisker och måste hanteras säkert. Tidigare utförda undersökningar av Garmin Venu-smartklockan lämnade utrymme för relevant framtida arbete. Det här examensarbetet siktar på att utföra ytterligare undersökningar av denna smartklocka. Arbetet tog inspiration av det relativt nya “PatrIoT” intrångstestmetodologin, internt utvecklad av personalen i avdelningen för nätverk och systemteknik, skräddarsydd för intrångstestning av Sakernas Internet-enheter. Det här projektet undersökte en bred attackyta på klockan, inkluderande datatrafik, data över USB-anslutning, några detaljer i klockans uppdateringsmekanism, undersökte närvaron av några mekanismer för minnesbaserade attacker, försök till störningsattacker i programvaruutvecklingssatsens applikationsprogrammeringsgränssnitt, med flera. Enligt dessa undersökningar uppfattas klockan vara säker. En djupare undersökning av dessa aspekter lämnas till framtida arbete.
