IOT Assessment

In a smart home setup, Henry is trying to connect various devices like lights and thermostats. He is considering two protocols for communication: MQTT and CoAP. What are the key differences between MQTT and CoAP in IoT networking?

• MQTT uses a publish/subscribe model with a broker, while CoAP uses a request/response model and allows direct device communication.

• CoAP uses a publish/subscribe model, while MQTT uses a request/response model.

• MQTT allows direct device communication, while CoAP requires a broker.

• MQTT is designed for high-latency networks, while CoAP is for low-latency networks.

Arjun is managing a smart home system that includes various IoT devices like smart thermostats, lights, and security cameras. Explain the role of the Lightweight M2M (LwM2M) protocol in IoT device management for his system.

• LwM2M is a protocol for real-time video streaming in IoT devices.

• LwM2M is primarily used for data storage in cloud services.

• LwM2M facilitates efficient remote management of IoT devices through standardized communication, enabling tasks such as provisioning, configuration, monitoring, and firmware updates.

• LwM2M focuses on enhancing user interfaces for IoT applications.

During a recent cybersecurity workshop, Aria learned about the various threats that can target IoT devices. She was particularly interested in understanding the most common threats. Can you identify three common cybersecurity threats specifically targeting IoT devices?

In a smart home setup, Benjamin is concerned about the security of his IoT devices. He wants to understand the significance of the CIA triad in IoT cybersecurity.

• It is only relevant for physical security measures.

• It emphasizes user interface design in IoT devices.

• The CIA triad is significant in IoT cybersecurity as it ensures the protection of data confidentiality, integrity, and availability.

• It focuses solely on data encryption.

Imagine Anika is managing a smart home system that connects various IoT devices. Describe how a Distributed Denial of Service (DDoS) attack can impact her IoT network.

• DDoS attacks can disrupt IoT networks by overwhelming devices with traffic, leading to service outages and performance issues.

• IoT networks are not immune to DDoS attacks due to their decentralized nature.

• DDoS attacks do not enhance the performance of IoT networks by optimizing traffic flow.

• DDoS attacks can affect both traditional web servers and IoT devices.

In a smart home managed by David, what methods can be employed to ensure the integrity of sensor data in IoT applications?
