Internet of Things (or IoT) devices have a notoriously bad reputation for security. As devices designed to have the smallest footprint possible (that is, to be tiny, low power, and cheap), manufacturers often resort (intentionally or not) to less-than-best security practices in order to lower their costs and maximize profits. This can be true of everything from smart home sensors, Wi-Fi-connected lightbulbs or smart home appliances. Especially if you’re buying from a region of the world where you might have broader security concerns, it’s best to take steps to keep these devices secure.
