The proliferation of IoT devices introduces cybersecurity challenges, including data breaches, unauthorized access, and device vulnerabilities. Security best practices such as network segmentation, encryption protocols, and regular firmware updates mitigate IoT-related risks. Identity and access management (IAM) frameworks ensure authorized device interactions and data privacy. Blockchain technology enhances IoT security by providing tamper-resistant data integrity and decentralized device authentication. Collaborative efforts between industry stakeholders, cybersecurity experts, and regulatory bodies are crucial for addressing evolving IoT security threats.
