Implementing Security Techniques to Lower the Probability of IoT-devices Getting Hacked
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 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.
