Cybersecurity Challenges and Solutions in Internet of Things (IoT) Networks

The Internet of Things (IoT) has transformed connectivity by integrating smart devices into daily life and industry. However, IoT's pervasive nature introduces significant cybersecurity challenges due to constrained device resources, heterogeneous networks, and diverse attack surfaces. This paper surveys current IoT cybersecurity threats, including device-level vulnerabilities, network attacks, and privacy issues. It further explores emerging solutions such as lightweight encryption, blockchain integration, and AI-driven anomaly detection. The discussion highlights the trade-offs between security, performance, and scalability in IoT deployments.
