Ethical Hacking Essentials Practice Test

What component of IoT technology collected incident data from CCTV devices and forwarded the information to Bob?

1. Gateways

2. Sensors

3. Middleware

4. Handlers

The correct answer is: Gateways

The correct component responsible for collecting incident data from CCTV devices and forwarding the information is the gateway. Gateways serve as crucial nodes in the Internet of Things (IoT) architecture; they connect various devices and facilitate communication between them and the broader internet or cloud services. In the scenario described, the gateway would capture data generated by the CCTV devices—such as video footage or motion detection alerts—and then relay that information to Bob or another designated endpoint. This functionality is essential for enabling real-time data processing and analysis in IoT setups. The other components play different roles in IoT schemes. Sensors are the devices that gather data from the physical environment, middleware acts as a bridge or layer that facilitates communication and data management between different systems and devices, while handlers are typically associated with processes or programs that manage specific tasks such as responding to events or executing commands. Each of these components has distinct functions, but in this specific context of data collection and forwarding, the gateway is the pivotal component.
