Recent Developments in IoT Security and Privacy: A Review of Best Practices with Challenges and Emerging Solutions

The Internet of Things has changed many fields by making it easy for smart devices to talk to each other. On the other hand, this change has led to major security and privacy problems, such as malware attacks, unauthorized access, data leaks, and weak authentication systems. IoT gadgets are easy targets for hackers because they often don't have a lot of processing power. Additionally, the massive data generated raises privacy concerns regarding unauthorized surveillance and data misuse. Traditional security measures are insufficient for IoT ecosystems, necessitating innovative solutions. Emerging approaches include blockchain for decentralized security, AI-driven anomaly detection, lightweight encryption techniques, and zero-trust architectures. Regulatory frameworks and technologies that protect privacy, such as federated learning and differential privacy, are also becoming more common. Even with these changes, it's still hard to find a good balance between privacy, security, and usability. It talks about the newest threats to privacy and security in the IoT as well as fresh methods to protect and strengthen the environment.
