The Internet of Things (IoT) represents a significant technological advancement, with billions of devices expected to be interconnected by 2025. Despite its benefits, IoT faces numerous security challenges due to the complexity and diversity of devices. This paper, authored by Abhijeet Anil, Chinmay Kumar Mahto, Lalit Kumar, Lokesh Kumar Sahu, and Dr. Ajay Gupta, delves into the security vulnerabilities of IoT systems and offers strategies to protect Arduino-based devices from common cyber threats.
Key topics and findings include:
Security Requirements: IoT devices must meet specific security goals, including confidentiality, integrity, authentication, availability, and non-repudiation. The paper highlights the increased vulnerability of IoT devices due to their limited computational and transmission capabilities.
Common IoT Security Threats: The study categorizes IoT attacks based on their impact on different architectural layers, such as application, network, and sensor layers. Examples of threats include unauthorized access, man-in-the-middle attacks, denial of service (DoS) attacks, and more.
Hardware-Based Security Solution: The authors propose using a hardware TCP/IP Ethernet module, specifically the WIZ5500, to protect Arduino IoT devices from DoS/DDoS attacks. By offloading network tasks to the hardware module, the system remains resilient to network performance degradation caused by attacks.
- WIZ5500 Ethernet Module: The WIZ5500 is a hardwired TCP/IP Ethernet controller that provides reliable internet connectivity for embedded systems. It supports multiple protocols and offers features like wake-on-LAN and power-down modes to enhance security and energy efficiency.
Experimental Setup: The study includes an experimental setup where the Arduino device is subjected to network attacks. Results demonstrate that using the WIZ5500 module significantly mitigates the impact of such attacks, maintaining stable network performance.
Countermeasures and Recommendations: The paper discusses various countermeasures for IoT attacks, such as authentication protocols, encryption techniques, and intrusion detection systems. It emphasizes the need for a multi-layered security approach to protect IoT devices throughout their lifecycle.
