Centralised DNS-based Malware Mitigation

Abstract

Malware presents a growing problem in a world that is increasingly connected to, and reliant on, the internet. The growing, devastating potential of cyber attacks such as DDoS attacks on society and economy is largely the result of a new class of devices, the Internet of Things (IoT), whose characteristic vulnerabilities make them easy targets to be compromised and controlled by malicious actors. This study employs a mixed-method research design to examine end-users' perceptions of the security of internet connected devices, their motivations for (non-)adoption of centralized DNS-based malware mitigation measures, and the efficacy of such services in mitigating malicious activity in a real-life environment. The results indicate that centralized DNS-based malware mitigation have significant potential in reducing end-user vulnerability to malware threats, but their adoption is hindered by lacking ability to assess threats and the value and efficacy of security measures.
