1. Introduction to IoT
- Traditional Internet Model: Servers provide services, and users interact with them via devices like PCs, laptops, and smartphones.
- IoT Definition: Extending internet connectivity to everyday devices (speakers, TVs, thermostats, cars, etc.).
- Driving Forces:
- Decreasing costs and size of electronic components.
- Widespread Wi-Fi and cellular internet access.
- Consumer demand for "smarter" devices.
- Growth of cloud computing (as IoT devices often rely on web services).
- Applications:
- Consumers: "Smart homes" (monitoring and controlling appliances).
- Business: Manufacturing, healthcare, transportation, etc.
- Security:
- IoT devices often have weak security measures.
- Compromised devices can be used as entry points into secure networks.
- They can also be used to launch remote attacks.
- Consumers often overlook security when connecting devices.
- Privacy:
- IoT devices collect data, which is often sent to cloud services.
- Concerns about how organizations handle personal data.
- Risk of data breaches, even with well-intentioned organizations.
- Devices like smart speakers pose risks of accidentally recording private conversations.
- Trade-off between convenience and privacy.
- Reliance on Cloud Services:
- Functionality can be limited or lost if the internet connection is down.
- Manufacturer may eventually discontinue service, rendering the device useless.
