Microsoft Cybersecurity Architect (SC-100)Evaluate Governance Risk Compliance (GRC) technical strategies and security operations strategiesMedium
A global manufacturing company is implementing an IoT solution across its factories. The cybersecurity architect needs to ensure that the vast number of IoT devices are securely provisioned, managed, and decommissioned in compliance with industry standards and internal policies. Which technical strategy offers the most scalable and secure approach for the entire lifecycle of these devices?
- AImplementing a centralized IoT device management platform that supports secure boot, over-the-air (OTA) updates, certificate-based authentication, and automated decommissioning.
- BUsing a simple API key for all IoT devices to authenticate to the cloud platform.
- CRelying on default vendor passwords and network segmentation to isolate IoT devices.
- DManually configuring each IoT device with unique credentials and updating firmware periodically.
Show answer & explanationAnswer & explanation
Correct answer: A. Implementing a centralized IoT device management platform that supports secure boot, over-the-air (OTA) updates, certificate-based authentication, and automated decommissioning.
A centralized IoT device management platform provides the scalability and security features (secure boot, OTA updates, certificate-based authentication, automated decommissioning) necessary to manage a large fleet of devices throughout their lifecycle, ensuring compliance and reducing manual effort.
Why the other options are wrong
- B. A simple API key for all devices creates a single point of failure and does not provide individual device identity, secure updates, or decommissioning capabilities necessary for compliance.
- C. Default vendor passwords are a major security vulnerability and network segmentation alone is insufficient to secure compromised devices or ensure proper lifecycle management.
- D. Manual configuration is not scalable for a vast number of IoT devices and is prone to errors, making it non-compliant and insecure.
IoT Device Management
The process of provisioning, authenticating, monitoring, updating, and decommissioning IoT devices throughout their operational lifecycle.
- Crucial for maintaining security and compliance in large IoT deployments.
- Often involves features like secure boot, firmware updates, and certificate management.
- Enables remote management and automation of device operations.
