Abstract:

IoT networks’ intrinsic vulnerabilities can be protected through intru- sion detection and response systems (IDRS). Anomaly-based intrusion detection offers multiple advantages: it can detect unknown attacks and it can adapt to multiple types of protocols. However, intrusion response is harder to carry out in combination with an anomaly-based detection system in part due to the possibility of false positive alerts. Through two implementations of IDRS in two distinct IoT networks, this thesis will highlight ways to improve anomaly-based detection and allow for appropriate response when possible

Cet objet connecté avait accès au réseau du casino, et les pirates ont réussi à le compromettre. Ils ont ensuite utilisé ce point d'entrée initial pour accéder à d'autres parties du réseau et ont finalement exfiltré 20 Go de données sensibles, y compris des informations sur les clients ”gros joueurs”.Cet exploit audacieux met en évidence la vulnérabilité des a

Abstract:

IoT devices are increasingly used in the process of gathering scientific data. In environmental monitoring IoT devices can be used as remote sensing devices to collect information about e.g. temperature. To keep data reliable, various security aspects have to be considered. Constrained devices are limited by memory size and battery life, a security solution has to be developed with this in mind. In this study an IoT security solution was developed in collaboration with a research group in environmental science at Umeå University. We selected commonly used algorithms and compare

The Internet of Things (IoT) is seen as one of the next Internet revolutions. In a near future the majority of all connected devices to the Internet will be IoT devices.

Object Security is a concept where the actual packet or sensitive parts of the packet are encrypted instead of the radio channel. A compromised node in the network will with this mechanism still have the data encrypted ensuring full end-to-end security. This paper proposes an architecture for

Abstract:

IoT security is something that is becoming more important with the exponential growing number of IoT devices. It is important to find methods that can make IoT devices more secure and are feasible to install and use. This paper investigates how effective the security features geographical IP based blocking (GeoIP) and a limit on the number of allowed sign-in attempts to a server (fail2ban) are at reducing the number of successful hacker attacks. By launching honeypots with and without these security features data was collected about the number of hacking attempts. The results shows that the Ge

Abstract:

The Internet of things (IoT) is a technology that will enable machine-to-machine communication and eventually set the stage for self-driving cars, smart cities, and remote care for patients. However, some barriers that organizations face prevent them from the adoption of IoT. The purpose of this qualitative exploratory case study was to explore strategies that organization information technology (IT) leaders use for security, privacy, and reliability to enable the adoption of IoT devices. The study population included organization IT leaders who had knowledge or perceptions of security, privac

Les technologies de l'Internet des Objets (IoT) ont transformé notre manière d'interagir avec le monde et les machines, devenant une partie intégrante de notre quotidien. Cette thèse vise à relever certains des défis rencontrés dans les environnements IoT en utilisant le Domain Name System (DNS) ainsi que ses extensions et protocoles de sécurité. Bien que le DNS soit principalement un système de recherche distribué permettant de mapper les noms de domaine aux adresses IP, il a considérablement évolué grâce à diverses de ses extensions. Cette évolution lui a permis de jouer un rôle plus large,

Abstract:

The emerging Internet of Things (IoT) revolution has introduced many useful applications that are utilized in our daily lives. Users can program these devices in order to develop their own IoT applications; however, the platforms and languages that are used during development are abounding, complicated, and time-consuming. The software solution provided in this thesis, PROVIZ+, is a secure sensor application development software suite that helps users create sophisticated and secure IoT applications with little software and hardware experience. Moreover, a simple and efficient domain-specific

Abstract:

Users share a large amount of information with modern platforms such as web platforms and social platforms for various services. However, they face the risk of information leakage because modern platforms still lack proper security policies. Existing security policies, such as permission systems and isolation, can help regulate information sharing. However, these policies have problems, such as coarse granularity, bad usability, and incompleteness, especially when new features are introduced. I investigate the security impacts of new features in web and mobile platforms and find design problem

Abstract:

Internetuppkopplade apparater blir allt vanligare att se i våra hem. Samlingsordet för dessa enheter är Internet of Things (IOT). Med införande av IoT i våra hem skapas fler accesspunkter till internet, vilket även skapar en större attackyta. I kombinationmed den ständigt växande cyberkriminalliteten och införandet av IoT i våra hem ökar risken för att utsättas för en attack. Tidigare forskning inom området gällande konsumenters informationssäkerhetsmedvetenhet visar att konsumenterna har låg medvetenhet och bristande kunskaper för de hot som tillkommer vid integrationen av en IoT-enhet ihemme

Abstract:

IoT is a rapidly growing area with products in the consumer, commercial and industrial market. Collecting data with multiple small and often battery-powered devices sets new challenges for both security and communication. There has been a distinct lack of a IoT specific communication protocols. The industry has had to use bulky interfaces not suitable for resource-constrained devices. MQTT is a standardised communication protocol made for the IoT industry. MQTT does however not have built-in security and it is up to the developers to implement a suitable security countermeasure.

Abstract:

With the the emergence of the Internet-of-Things (IoT) and Cyber-Physical Systems (CPS), modern computing is now transforming from residing only in the cyber domain to the cyber-physical domain. I focus on one important aspect of this transformation, namely shortcomings of traditional security measures. Security research over the last couple of decades focused on protecting data in regard to identities or similar static attributes. However, in the physical world, data rely more on physical relationships, hence requires CPS to verify identities together with relative physical context to provide

Internet Of Things (IoT) och hemautomation innebär möjligheten att koppla upp diverse enheter i ett hem gentemot internet, som därefter har som mål att underlätta och göra konsumenters vardag mer bekvämt. Hemautomation kan exempelvis handla om att låsa dörrar och tända lampor från en enda enhet (kontrollern), vilket underlättar då konsumenten inte behöver gå till vardera enhet för att utföra önskade aktiviteter. Kontrollers är den del av ett IoT-system inom hemautomation som agerar gränssnittet mellan konsumenten och enheterna.Open-source erbjuder konsumenter ett mer fritt nyttjande av produkt
