Minska sannolikheten för IoT enheter att bli hackade (Swedish)
Abstract [en]

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 GeoIP security feature can reduce attacks by roughly 93% and that fail2ban can reduce the attacks by 99%. Further work in this field is encouraged to create better GeoIP tools and to better understand the potential for these security techniques on a larger scale.

Abstract [sv]

IoT-säkerhet är ett fält med en allt mer ökad relevans i dagens samhälle i och med den exponentialla tillväxten av IoT-enheter. Det är viktigt att hitta metoder som kan göra IoT-enheter säkrare och är enkla att installera och använda. Den här rapporten undersöker hur effektiva geografiskt baserad IP-blockningar (GeoIP) och en begränsning i antalet tillåtna inloggningsförsök till en server (fail2ban) kan vara i att minska antalet lyckade attacker mot IoT-enheter. Genom att sätta upp honeypots med och utan de tidigare nämnda säkerhetsfunktionerna kunda vi samla data på hur de påverkade antalet attacker. Resultaten visade att GeoIP reducerade antalet med ungefär 93% och att fail2ban reducerade antalet med ungefär 99%. Framtida arbete inom detta fält kan vara att skapa en snabbare och mer simpel GeoIP modul och att försöka förstå hur dessa säkerhetstekniker kan påverka IoT-enheter i en större skala.
