While HIDs vary in terms of hardware and software, the OS detects them as genuine, providing access to the malicious HID to perform and execute privileged actions as if it came from a genuine user. Since the threat can bypass normal security controls, it poses a significant challenge to security managers. While the insider (both unintentional and malicious) threat level posed by the malicious HIDs is high, research in the domain of mapping HIDs to HID attack vectors and the exploited vulnerabilities is scarce, which is evident from the paucity of research outputs in a Google Scholar search. Accordingly, the objective of this research is to create a model that maps HIDs to vulnerability categories aligned to attacks. In this connection, the paper proposes an HID Threat Vulnerability model (HidTV) that identifies the malicious HID types and evaluates the nature of HID related threats and the corresponding vulnerabilities that are exploited. The resulting model can provide security managers with a visibility of critical vulnerabilities, map specific HIDs to threats and vulnerabilities and formulate security policies to defend and mitigate against these threats. From an academic perspective, the paper provides a foundation for researchers to evaluate and propose detective and mitigation strategies for specific attack paths. While there are genuine uses for HIDs, this paper focuses on the ways they can be intentionally exploited for malicious purposes.}, publisher={ISRES Publishing}
