  Our research sets out to look at how this system of interconnected smart devices affects our privacy.. and how can we show this with a practical analysis and vulnerability analysis of our own smart devices.

  Even though the attack surface of SPA is conspicuously broad and there has been a significant amount of recent research efforts in this area, research has so far focused on a small part of the attack surface.. this is the first..  characterization of the security and privacy issues and countermeasures of SPA.

  We conclude that though numerous privacy concerns and security vulnerabilities associated with the device are mitigated, many vulnerabilities still need to be addressed.
