Home IoT Device Security


There are a lot of home IoT (Internet of Things) devices at your home these days. Smartphones, tablets and smartwatches are very common. Smart TVs, fridges and even door locks and multiplugs are now connected to the Internet nowadays. I will discuss how securely these devices are communicating through the web.


  1. Network basics
  2. Wireshark and traffic captures (hands-on training)
  3. How IoT devices works
  4. Raspberry Pi and WiFi AP
  5. How you can secure these devices


Name: Su-Hyun Park
Bio :
Senior software engineer on embedded arena, from small IoT device to large scale network security appliance, UTM.

Started programming since mid-80’s (since 8 years old) on XT-PC, pre MS-DOS generation.
Have experienced more than 20 programming languages over 30 years, but now I am a linux systems software engineer developing on kernel module and user space applications especially on embedded systems.

On the other hand, I am a full-stack engineer. Developing from Android app to the back-end server applications for hobby project.
