4. Why Top 10 for IOT ??
• The internet of things (IoT) is the network of physical devices,
vehicles, buildings and other items—embedded with electronics,
software, sensors, actuators, and network connectivity that enable
these objects to collect and exchange data(Wikipedia)
• 26 Billion devices connected to Internet by 2020
• Current Security State - still in nascent stage.
• Thus, scope for hackers  HIGH

5. Attack Vectors????
Lets have a look at the architecture and derive all the attack vectors

6. IOT Architecture

7. Attack Vectors List
• All elements need to be considered
• Communication Protocol
• The Cloud
• The Mobile Application
• The Network Interfaces
• Web Interface
• Encryption
• Authentication/Authorization
• Physical ports(JTAG,UART,SPI,I2C)
• Enter the OWASP Internet of Things Top Ten Project
