Understanding VPC and Its Role in IoT Security
A Virtual Private Cloud (VPC) is a dedicated network environment that isolates your IoT devices from the public internet, enhancing security. VPC allows you to define subnets, access control lists, and security groups to manage traffic and permissions effectively.
Why is VPC crucial for IoT?
- Protects devices from unauthorized access.
- Enables secure communication between IoT devices.
- Reduces the risk of data breaches.
By leveraging VPC, you can ensure that your IoT devices are operating in a secure and controlled environment, reducing the risk of cyberattacks.
VPC Components
A VPC typically consists of the following components:
- Subnets: Divides the VPC into smaller networks for better management.
- Route Tables: Defines the routing rules for network traffic.
- Security Groups: Acts as a virtual firewall for your instances.
Understanding these components is essential for setting up a secure IoT VPC.
Setting Up Raspberry Pi for IoT
The Raspberry Pi is a versatile and cost-effective device for managing IoT networks. It can act as a central hub for connecting multiple IoT devices and managing their interactions.
Steps to Set Up Raspberry Pi:
- Install Raspberry Pi OS on your device.
