Common IOT attacks

1. Common IoT Attacks Understanding Security Threats in the Internet of Things M.Sc. Electronics (NEP 2.0) Semester IV - 2025 By: [Your Name]

2. 1. Introduction to IoT Security • Internet of Things (IoT) connects billions of devices globally. • IoT security ensures protection of devices, networks, and data. • Limited device resources make IoT systems more vulnerable. • Understanding common attack types helps in designing secure systems.

3. 2. Malware and Botnet Attacks • IoT devices can be infected with malware forming botnets. • Botnets launch Distributed Denial of Service (DDoS) attacks. • Example: Mirai botnet (2016) disrupted major web services. • Prevention: Secure firmware, update policies, strong authentication.

4. 3. Man-in-the-Middle (MitM) Attacks • Attackers intercept communication between IoT devices and servers. • Can lead to data theft or manipulation. • Often occurs on unsecured Wi-Fi connections. • Prevention: Use SSL/TLS encryption, VPNs, and secure key exchange.

5. 4. Firmware and Software Exploits • Many IoT devices run outdated firmware. • Attackers exploit vulnerabilities for unauthorized access. • Malicious code can modify or disable device functionality. • Prevention: OTA (Over-The-Air) updates and code signing verification.

6. 5. Physical Attacks • Attackers physically access devices to extract data or modify hardware. • Techniques include port probing, chip removal, or reverse engineering. • Prevention: Secure enclosures, disable unused ports, and tamper-proof design.

7. 6. Data Privacy and Eavesdropping • IoT devices transmit sensitive data which can be intercepted. • Leads to privacy violations and data misuse. • Prevention: Encrypt communication, anonymize user data, and restrict cloud access.

8. 7. Denial of Service (DoS) Attacks • Attackers flood IoT networks with requests causing service disruption. • Example: IoT-based DDoS attacks on Dyn DNS servers. • Prevention: Firewalls, rate limiting, and anomaly detection systems.

9. 8. Best Practices for IoT Security • Change default credentials and enforce strong passwords. • Implement device authentication and encryption. • Regular firmware updates and vulnerability scans. • Use network segmentation and intrusion detection systems.

10. Conclusion • IoT expands connectivity but also introduces security risks. • Awareness of common attacks is essential for building secure systems. • Implementing layered security can protect IoT infrastructure effectively.
