Which of the following is NOT a recommended best practice for securing IoT devices?

  1. Use strong passwords and change them regularly.

  2. Keep IoT devices up to date with the latest firmware and security patches.

  3. Disable unused services and ports on IoT devices.

  4. Connect IoT devices to a public Wi-Fi network.


Correct Option: D
Explanation:

Connecting IoT devices to a public Wi-Fi network is not recommended as it can expose them to unauthorized access and attacks.

What is the primary purpose of using a firewall in an IoT network?

  1. To block unauthorized access to the network.

  2. To monitor network traffic for suspicious activity.

  3. To prevent the spread of malware and viruses.

  4. To optimize network performance.


Correct Option: A
Explanation:

The primary purpose of a firewall in an IoT network is to block unauthorized access to the network and protect it from external threats.

Which of the following is a common type of attack that targets IoT devices?

  1. Phishing

  2. Man-in-the-middle attack

  3. Distributed denial-of-service (DDoS) attack

  4. Malware infection


Correct Option: D
Explanation:

Malware infection is a common type of attack that targets IoT devices, allowing attackers to gain control of the devices and use them for malicious purposes.

What is the recommended approach for securing IoT devices that lack built-in security features?

  1. Use a virtual private network (VPN) to encrypt network traffic.

  2. Install a third-party security solution on the device.

  3. Disable remote access to the device.

  4. Change the default username and password of the device.


Correct Option: B
Explanation:

Installing a third-party security solution on an IoT device that lacks built-in security features can provide additional protection against threats.

Which of the following is a best practice for managing IoT devices securely?

  1. Maintain an inventory of all IoT devices connected to the network.

  2. Regularly monitor IoT devices for suspicious activity.

  3. Apply security updates and patches to IoT devices promptly.

  4. All of the above


Correct Option: D
Explanation:

All of the above practices are important for managing IoT devices securely and protecting them from potential threats.

What is the recommended approach for securing IoT networks?

  1. Use a strong firewall to protect the network from unauthorized access.

  2. Implement network segmentation to isolate different parts of the network.

  3. Use intrusion detection and prevention systems to monitor network traffic for suspicious activity.

  4. All of the above


Correct Option: D
Explanation:

All of the above practices are important for securing IoT networks and protecting them from potential threats.

Which of the following is NOT a recommended best practice for securing IoT data?

  1. Encrypt IoT data in transit and at rest.

  2. Store IoT data in a secure location.

  3. Use strong encryption keys and regularly rotate them.

  4. Share IoT data with third parties without proper authorization.


Correct Option: D
Explanation:

Sharing IoT data with third parties without proper authorization is not a recommended best practice as it can increase the risk of data breaches and unauthorized access.

What is the primary purpose of using a secure boot process in IoT devices?

  1. To prevent unauthorized software from being loaded onto the device.

  2. To verify the integrity of the device's firmware.

  3. To protect the device from malware and viruses.

  4. To improve the device's performance.


Correct Option: A
Explanation:

The primary purpose of using a secure boot process in IoT devices is to prevent unauthorized software from being loaded onto the device, ensuring that only authorized and trusted software is executed.

Which of the following is a recommended best practice for securing IoT devices that are exposed to the internet?

  1. Use a VPN to encrypt network traffic.

  2. Implement two-factor authentication (2FA) for remote access.

  3. Use a firewall to block unauthorized access to the device.

  4. All of the above


Correct Option: D
Explanation:

All of the above practices are important for securing IoT devices that are exposed to the internet and protecting them from potential threats.

What is the recommended approach for managing IoT device credentials securely?

  1. Use strong passwords and change them regularly.

  2. Store credentials in a secure location.

  3. Use a password manager to generate and store credentials securely.

  4. All of the above


Correct Option: D
Explanation:

All of the above practices are important for managing IoT device credentials securely and protecting them from potential threats.

Which of the following is NOT a recommended best practice for securing IoT devices that are used in critical infrastructure?

  1. Implement role-based access control (RBAC) to restrict access to IoT devices.

  2. Use strong encryption to protect sensitive data.

  3. Regularly monitor IoT devices for suspicious activity.

  4. Connect IoT devices to a public Wi-Fi network.


Correct Option: D
Explanation:

Connecting IoT devices to a public Wi-Fi network is not a recommended best practice for securing IoT devices that are used in critical infrastructure, as it can expose them to unauthorized access and attacks.

What is the recommended approach for securing IoT devices that are used in healthcare applications?

  1. Implement strong authentication and authorization mechanisms.

  2. Encrypt patient data in transit and at rest.

  3. Regularly update IoT devices with the latest security patches.

  4. All of the above


Correct Option: D
Explanation:

All of the above practices are important for securing IoT devices that are used in healthcare applications and protecting patient data from potential threats.

Which of the following is NOT a recommended best practice for securing IoT devices that are used in industrial applications?

  1. Implement network segmentation to isolate IoT devices from other parts of the network.

  2. Use strong encryption to protect sensitive data.

  3. Regularly monitor IoT devices for suspicious activity.

  4. Connect IoT devices to a public Wi-Fi network.


Correct Option: D
Explanation:

Connecting IoT devices to a public Wi-Fi network is not a recommended best practice for securing IoT devices that are used in industrial applications, as it can expose them to unauthorized access and attacks.
