Introduction to IoT Security
The Internet of Things (IoT) refers to the network of physical devices embedded with sensors, software, and connectivity that enables them to exchange data. However, with great connectivity comes great responsibility—ensuring the security of these devices is paramount. IoT security involves protecting IoT devices and networks from unauthorized access, data breaches, and other cyber threats.
Why IoT Security Matters
IoT devices are often used in critical applications such as healthcare, transportation, and smart homes. A breach in IoT security can lead to severe consequences, including data theft, privacy violations, and even physical harm. Therefore, implementing robust security measures is essential.
- Protect sensitive data transmitted between devices.
- Prevent unauthorized access to IoT devices.
- Ensure the integrity and reliability of IoT systems.
Understanding P2P Technology
Peer-to-peer (P2P) technology allows devices to communicate directly with each other without relying on a central server. This decentralized approach offers several advantages, including increased efficiency, reduced latency, and enhanced privacy.
Benefits of P2P Technology
- Decentralization: Eliminates the need for a central server, reducing single points of failure.
- Scalability: Can handle a large number of devices without performance degradation.
- Privacy: Data is transmitted directly between devices, minimizing exposure to third parties.
Raspberry Pi Overview
Raspberry Pi is a small, affordable computer that has become a popular choice for IoT projects. Its versatility, ease of use, and extensive community support make it an ideal platform for experimenting with IoT technologies.
Key Features of Raspberry Pi
- Compact size and low power consumption.
- Support for various operating systems, including Linux distributions.
- Wide range of GPIO pins for interfacing with sensors and actuators.
Securing Remote IoT Devices
