The recommended security practice for protecting smart devices from IoT threats is the implementation of Intrusion Prevention Systems (IPS) and Intrusion Detection Systems (IDS) in the network. This approach is effective because both IPS and IDS play crucial roles in monitoring and managing network traffic.

An Intrusion Detection System monitors network traffic for suspicious activity and issues alerts when such activity is detected. By identifying potential threats in real-time, organizations can respond quickly to security breaches. On the other hand, an Intrusion Prevention System goes a step further by actively blocking or preventing identified threats from causing harm to the network.

This layered defense strategy is essential for IoT environments, where devices often have varying levels of security and can be more susceptible to attacks. By employing IPS and IDS, organizations can enhance their visibility into network activity surrounding these connected devices and take proactive measures to secure their infrastructure against IoT threats.

In contrast, relying solely on firewalls does not provide complete protection, as they might not detect or prevent sophisticated threats that IPS and IDS can address. Regular updates of mobile applications are also important, but they do not specifically target IoT devices as a broader defense mechanism does. Basic password security, while fundamentally necessary, is typically insufficient on its own to defend against more advanced
