2.4 Internet of Things Flashcards
What is the Internet of Things (IoT)?
A network of devices embedded with sensors, software, and connectivity to gather and exchange data.
What types of devices are considered IoT devices?
Devices like smart thermostats, IP cameras, wearables, building automation systems, and industrial equipment.
What protocols are commonly used by IoT devices?
Z-Wave, Zigbee, Wi-Fi, and Bluetooth.
Why should IoT devices be segregated from business networks?
To prevent breaches, as IoT devices are often less secure and can act as entry points for attackers.
What was a key lesson from the 2014 Target breach?
Segregating IoT devices (like HVAC systems) from business networks can prevent breaches.
What are examples of IoT hub and control systems?
Centralized controllers like Amazon Echo that manage smart devices.
What are examples of IoT smart devices?
Smart thermostats, video doorbells, smart light bulbs.
What are IoT wearables?
Smart devices designed to be worn, such as fitness trackers and smart glasses.
What are examples of IoT sensors?
Sensors measuring temperature, motion, humidity, or heart rates.
How are IoT devices used in building automation?
Managing lighting, HVAC, and security systems for efficiency and comfort.
What are IP video systems used for?
Video conferencing and surveillance; require significant bandwidth and security measures.
What are access control systems in IoT?
Proximity readers, biometric scanners, and security cameras.
Why is it important to isolate industrial IoT equipment?
To ensure safety and security, as these systems often control critical factory or hospital operations.
How does IoT improve business and industry?
By enhancing efficiency, reducing costs, and enabling automation.
What is the primary security concern for IoT devices?
Their vulnerability to breaches if not properly isolated or secured.
