Analyzing the security of Wearable Internet-of-Things (WIoT) devices is considered a complex task due to
their heterogeneous nature. In addition, there is currently no mechanism that performs security testing
for WIoT devices in different contexts. In this article, we propose an innovative security testbed framework
targeted at wearable devices, where a set of security tests are conducted, and a dynamic analysis is performed
by realistically simulating environmental conditions in which WIoT devices operate. The architectural design
of the proposed testbed and a proof-of-concept, demonstrating a preliminary analysis and the detection of
context-based attacks executed by smartwatch devices, are presented.
