CertNexus Certified Cyber Secure Coder (CSC) — Question 44

To minimize vulnerability, which steps should an organization take before deploying a new Internet of Things (IoT) device? (Choose two.)

Answer options

• A. Changing the default password
• B. Updating the device firmware
• C. Setting up new users
• D. Disabling IPv6
• E. Enabling the firewall

Correct answer: B, E

Explanation

Updating the device firmware (B) ensures that any security vulnerabilities from previous versions are patched, while enabling the firewall (E) helps protect the device from unauthorized access. Changing the default password (A) and setting up new users (C) are good practices, but they do not provide the same level of security improvement as the firmware update and firewall activation. Disabling IPv6 (D) may limit functionality without significantly enhancing security.
