Data Access Control
Controlling who can access and modify data on your IoT devices is crucial. Role-based access control (RBAC) allows you to define user permissions and restrict unauthorized actions, enhancing security.

Security Testing
Regularly test your IoT devices for vulnerabilities. Vulnerability assessments and penetration testing can help identify weaknesses in your security measures before malicious actors exploit them.

User Education
Educating end-users is often an overlooked aspect of IoT security. It's essential to raise awareness among users about the risks and best practices, such as changing default passwords and recognizing suspicious activity.

Privacy by Design
Consider privacy as a fundamental design principle. Implement privacy protection measures, including data anonymization and minimizing data collection, to reduce the exposure of sensitive information.
