  For smart homes to be safe homes, they must be designed with security in
mind. Yet, despite the widespread proliferation of connected digital
technologies in the home environment, there is a lack of research evaluating
the security vulnerabilities and potential risks present within these systems.
Our research presents a comprehensive methodology for conducting systematic IoT
security attacks, intercepting network traffic and evaluating the security
risks of smart home devices. We perform hundreds of automated experiments using
11 popular commercial IoT devices when deployed in a testbed, exposed to a
series of real deployed attacks (flooding, port scanning and OS scanning). Our
findings indicate that these devices are vulnerable to security attacks and our
results are relevant to the security research community, device engineers and
the users who rely on these technologies in their daily lives.
