Two-factor authentication, requiring both a password and a security key or biometric, should be used whenever possible for IoT devices. This provides an extra layer of protection for your network.

For device access control, use the principle of least privilege, which means only granting the minimum access needed to authorized users and devices. Don’t give full network access to any IoT device unless absolutely necessary. Segment your network into zones by access level, and place IoT devices in zones with limited access based on their specific needs. Monitor device access continuously to detect any unauthorized access attempts.

Consider using device certificates to authenticate IoT devices, which provide a higher level of security than just a username and password. The certificate establishes the device’s credentials and is installed on the device during manufacturing or deployment. The network then only allows connections from devices with a trusted certificate. This helps prevent man-in-the-middle attacks.

Use role-based access control to assign permissions to IoT devices based on their intended functions. For example, a smart thermostat may only need access to the local network zone, while a security camera may need access to certain servers to upload footage. Determine the proper level of access for each device type and grant only the necessary permissions.

Continuously monitor your IoT devices and network for any signs of compromised credentials or unauthorized access. Watch for unknown or unexpected devices connecting to the network, as well as logins from unknown or overseas IP addresses. Any detected intrusions should be addressed immediately to avoid data breaches or network disruptions.

With strong authentication, least privilege, network segmentation, device certificates, role-based access control, and continuous monitoring, you can securely manage access for all your connected IoT devices and help prevent unwanted intrusions into your network. The risks are real, so a robust IoT security strategy is essential.
