What is threat modeling in the context of telemetry platforms?

• A. A process for measuring data throughput
• B. A method for risk assessment that ignores mitigations
• C. A protocol for user authentication
• D. A structured approach to identifying threats, assessing risk, and implementing mitigations

Answer: (D)

Threat modeling is a proactive, structured process for identifying security threats to a telemetry platform, assessing the associated risks, and planning mitigations before issues arise. In practice, you map out critical assets like telemetry data, devices, APIs, and credentials; model potential attackers and attack vectors; and trace data flows from devices through gateways to cloud services to spot where confidentiality, integrity, or availability could be at risk. For each potential threat, you evaluate how likely it is and how severe the impact would be, so you can prioritize what to fix. You then design and implement mitigations—such as strong authentication and authorization, encryption in transit and at rest, secure update mechanisms, robust access controls, auditing, and continuous monitoring—and verify that these controls effectively reduce risk. In the telemetry context, this helps keep data private, prevent device compromise, maintain service availability, and avoid leaks or tampering across integrations. The other options describe measuring throughput, ignoring mitigations, or focusing on a single authentication protocol, none of which capture this comprehensive, forward-looking process.
