Evaluating the security of a smart door lock system

Veijalainen, Sebastian, Noreng Karlsson, Tommy January 2021 (has links)
Smart home appliances and IoT devices in general are a fast growing market. Smart door locks are one type of device which is included in these categories. The smart door lock replaces a common deadbolt lock. In this study a smart door lock was penetration tested. The project started with a literature study, followed by a reconnaissance phase for gathering information about the smart door lock system. A threat model was created based on the findings during the reconnaissance phase and with the help of the STRIDE and DREAD frameworks. Penetration tests were chosen and conducted based on the threat model. The results of the penetration tests showed no major vulnerabilities, but a weakness in the communications between the mobile app and the server. / Smarta apparater och generellt enheter på sakernas internet är en snabbt växande marknad. Smarta dörrlås är en slags enhet som inkluderas i dessa kategorier. I den här studien penetrationstestades ett smart dörrlås. Projektet började med en litteraturstudie, följt av en spaningsfas för att samla in information om det smarta låssystemet. En hotmodell skapades baserad på fynden från spaningsfasen och med hjälp av ramverken STRIDE och DREAD. Penetrationstester valdes och genomfördes baserat på hotmodellen. Resultaten från penetrationstesterna visade inga större sårbarheter, men en svaghet i kommunikationen mellan mobilappen och värddatorn.

Penetration testing of Sesame Smart door lock / Penetrationstest av Sesame Smart dörrlås

Liu, Shuyuan January 2023 (has links)
The Internet of things (IoT) device has been widely used in various fields, and its market is expanding rapidly. However, the growing usage of IoT devices also brings more security concerns. The smart door lock is one of the smart home IoT devices that need to be designed securely. This thesis work aims to evaluate and investigate the security aspect of the newest smart door lock. This thesis first provides an introduction and background of penetration testing and creates the threat model. Based on the threat model, some testings are conducted, including state consistency, Man-In-The-Middle (MITM) attack, replay attack, reverse engineering, GPS spoofing, Denial of service (DoS) attack. The result indicates that penetration tests reveal some security problems on the tested device, especially in the access log, traffic between application and server, and the ability of resistance disruption on the WiFi access point. / IoT-enheten har använts i stor utsträckning inom olika områden och dess marknad expanderar snabbt. Den ökande användningen av IoT-enheter medför dock också fler säkerhetsproblem. Det smarta dörrlåset är en av de smarta hem IoT-enheterna som måste utformas säkert. Detta examensarbete syftar till att utvärdera och undersöka säkerhetsaspekten av det nyaste smarta dörrlåset. Denna avhandling ger först en introduktion och bakgrund av penetrationstestning och skapar hotmodellen. Baserat på hotmodellen genomförs vissa tester, inklusive tillståndskonsistens, MITM attack, replay attack, reverse engineering, GPS spoofing, DoS attack. Resultatet indikerar att penetrationstester avslöjar vissa sårbarheter på den testade enheten, särskilt i åtkomstloggen, trafik mellan applikation och server och förmågan till motståndsavbrott på WiFi-åtkomstpunkten.
