[MUSIC] So what about IOT in our homes? Is that possible? Not only is it possible, it's happening everyday and in ways you may or may not even be aware of. In this module, we will look at some of the more common IOT devices in use in a modern, connected home and how they are used. We will also look at some of the big security and privacy related issues found in these devices and their use in our homes. Safety and security are at the forefront of most people's minds nowadays, especially when it relates to their home and personal property. The IOT allows everyday people like you and me to outfit our homes and property with devices like security cameras. Some cameras are designed to be placed inside the house, so that you can monitor the indoor activity whenever you want to. Other cameras are camouflaged for outdoor use, so that you can monitor the outside of your home as well. Finally some cameras are disguised as things like doorbells so that you can see who's knocking at your front door, even if you're far away at the time. These doorbell cameras can also have microphones and speakers built into them, so that you can interact with a visitor, even when you're away. Another big area of IOT growth in the connected home revolves around kitchen appliances. We can now purchase devices that keep track of how cold our eggs are. Brew coffee straight from our smart phone. Decant wine. Track caloric intake. Help us eat our food at optimal speed. Monitor the temperature at which our food is cooking, and the list goes on. Smart thermostats are becoming more and more common in homes today. Some of these devices can be used to monitor activity in the home, for purposes of determining routines that help determine the most efficient times to heat or cool the home. These thermostats can help homeowners use energy more efficiently, thus lowering their monthly cost, as well as the overall strain on the energy grid. All of this sounds wonderful, right? We can manage our homes with just a touch of a few buttons or mouse clicks. However, what about the security and privacy implications of these devices? Almost all of these devices communicate data to a third party via the Internet. What type of data is being shared? Is that data encrypted before it's sent? What can third parties learn about us simply by analyzing the data sent to them? Recently, a very popular brand of smart thermostat was discovered to be sending data in plain text that anyone could intercept and read. Also, a very popular brand of smart doorbell devices encountered an error, with the end result being that any user could view any other user's doorbell camera feed. [SOUND]
