Ensuring that IoT devices are placed in a segregated network will reduce the risk of them becoming a point of entry for network attacks, as they would not have direct access to the main corporate network where sensitive data might be stored. Regularly updating the firmware of these devices can also address security vulnerabilities that could be exploited by attackers. Using strong, unique passwords is important to prevent unauthorized access, but it does not address the potential of the devices being used as part of a network attack. Disabling unnecessary services is a general good security practice, but it is not specific to the integration and security of IoT devices like smart speakers.
