IOT IoT Security 2

Question 1

Which IoT security framework was developed by NIST to provide guidelines for managing IoT cybersecurity risks?

Accepted Answer

NIST Cybersecurity Framework

Answer

The NIST Cybersecurity Framework provides guidelines and best practices for managing cybersecurity risk, including for IoT deployments.

Question 2

What is a 'botnet' in the context of IoT security threats?

Accepted Answer

A network of compromised IoT devices controlled by an attacker

Answer

An IoT botnet is a collection of compromised devices that an attacker controls remotely, often used to launch DDoS attacks.

Question 3

Which cryptographic concept ensures that an IoT device's firmware has not been tampered with since it was signed?

Accepted Answer

Code signing

Answer

Code signing uses digital signatures to verify that firmware has not been altered since it was signed by the manufacturer.

Question 4

What does 'network segmentation' mean in an IoT deployment context?

Accepted Answer

Isolating IoT devices on a separate network from critical business systems

Answer

Network segmentation isolates IoT devices on their own network segment to prevent a compromised device from accessing critical systems.

Question 5

Which attack type floods an IoT device or network with traffic to make it unavailable to legitimate users?

Accepted Answer

Denial of Service (DoS)

Answer

A Denial of Service (DoS) attack overwhelms an IoT device or network with traffic, causing it to become unresponsive.
