How can I ensure secure device authentication in IoT networks?

Access control for IoT devices is crucial for ensuring security and protecting sensitive data. Role-based permissions enable administrators to assign specific roles or access levels to different users or devices. This helps restrict unauthorized access and control over the IoT devices and their data. Multi-factor authentication adds an extra layer of security by requiring users to provide multiple forms of verification before gaining access, such as something they know (password), something they have (smartphone for receiving a code), or something they are (biometric data). Together, these measures help in enhancing the security of IoT systems and preventing unauthorized use.
