The Internet of Things (IoT) has become one of the fastest-growing technologies in the modern digital world. Smart devices are now used in homes, hospitals, transportation systems, industries, and many other areas of everyday life. These devices make human life more convenient by allowing automation, remote monitoring, and real-time communication. However, together with these advantages, IoT technologies also introduce serious cybersecurity risks. Many IoT devices are developed with limited memory, low processing power, and weak security configurations, which makes them vulnerable to cyberattacks. As the number of connected devices continues to increase, protecting IoT systems becomes more difficult and more important.
This paper discusses the major security challenges in IoT environments and analyzes modern approaches proposed to solve these problems. In particular, the paper focuses on authentication mechanisms, blockchain-based security solutions, lightweight cryptography, digital forensics, and trust management systems. The study also examines the limitations of existing IoT security architectures and explains why blockchain technology is considered one of the most promising solutions for future IoT ecosystems. The analysis shows that combining blockchain technology with lightweight security mechanisms can significantly improve data integrity, authentication, confidentiality, and trust in IoT networks.
