Ethical Hacking for IoT Security: A First Look into Bug Bounty Programs and Responsible Disclosure
This addresses the pressing need for practical security solutions for IoT companies, consumers, and regulators, but it is an incremental study focusing on an unexplored application area.
The paper tackles the problem of IoT security vulnerabilities by exploring the potential of bug bounty programs and responsible disclosure for effective and cost-efficient vulnerability management, deriving tangible guidelines for stakeholders and proposing systematic integration with existing security practices.
The security of the Internet of Things (IoT) has attracted much attention due to the growing number of IoT-oriented security incidents. IoT hardware and software security vulnerabilities are exploited affecting many companies and persons. Since the causes of vulnerabilities go beyond pure technical measures, there is a pressing demand nowadays to demystify IoT "security complex" and develop practical guidelines for both companies, consumers, and regulators. In this paper, we present an initial study targeting an unexplored sphere in IoT by illuminating the potential of crowdsource ethical hacking approaches for enhancing IoT vulnerability management. We focus on Bug Bounty Programs (BBP) and Responsible Disclosure (RD), which stimulate hackers to report vulnerability in exchange for monetary rewards. We carried out a qualitative investigation supported by literature survey and expert interviews to explore how BBP and RD can facilitate the practice of identifying, classifying, prioritizing, remediating, and mitigating IoT vulnerabilities in an effective and cost-efficient manner. Besides deriving tangible guidelines for IoT stakeholders, our study also sheds light on a systematic integration path to combine BBP and RD with existing security practices (e.g., penetration test) to further boost overall IoT security.
