Exam CFR-310 topic 1 question 93 discussion

A. Changing the default password Explanation: Many IoT devices come with default passwords, which are often publicly known. Changing the default password to a strong, unique one is essential to protect the device from unauthorized access. B. Updating the device firmware Explanation: Before deployment, ensuring that the device has the latest firmware helps address any security vulnerabilities that may have been patched by the manufacturer. Incorrect Responses: C. Setting up new users: This can be useful in managing access but is not as critical for minimizing vulnerability as changing default passwords or updating firmware. D. Disabling IPv6: This is not a general security measure unless specific network-related vulnerabilities are known. E. Enabling the firewall: While enabling a firewall is useful, many IoT devices may not have built-in firewalls, and the primary concern is securing the device itself.
