The Internet of Things (IoT) has become an integral part of modern life, connecting billions of devices across various domains such as healthcare, home automation, and smart mobility. However, the rapid proliferation of IoT devices has introduced significant cybersecurity threats, making it crucial to understand and mitigate these risks.
Lack of Strong Security Mechanisms: Many low-end IoT devices do not support robust security measures, making them vulnerable to various attacks such as data leakage, denial of service (DoS), and unauthorized access .
Privacy and Data Confidentiality Risks: IoT devices often collect and exchange sensitive data, posing significant privacy risks if compromised. Unauthorized access to these devices can lead to data theft and misuse .
Vulnerabilities in Communication Protocols: The communication protocols used by IoT devices often have security weaknesses, making them susceptible to attacks that can compromise data integrity and confidentiality .
DDoS Attacks: IoT devices can be exploited to launch Distributed Denial of Service (DDoS) attacks, overwhelming networks and causing service disruptions .
Challenges in Implementing Lightweight Security: Due to limited resources and computing power, it is challenging to implement effective security models for IoT devices, leaving them exposed to cyber threats.
The rapid expansion of IoT devices has introduced significant cybersecurity challenges, primarily due to weak security mechanisms, privacy risks, and vulnerabilities in communication protocols. Addressing these issues requires the development of lightweight yet robust security solutions to protect IoT devices from various cyber threats.
