IoT Device Security Assessment

Overview

This engagement involved a comprehensive security assessment of IoT devices deployed in industrial environments. The client required validation of both hardware and firmware before expanding deployment.

Scope

• Hardware teardown and reverse engineering
• Firmware extraction and analysis
• Communication protocol review (MQTT, CoAP)
• Authentication and encryption assessment
• Supply chain considerations

Findings

Key findings included firmware update mechanisms without integrity verification and debug interfaces left enabled in production units. Recommendations were implemented prior to wider rollout.

Outcome

The client addressed all critical and high-severity findings and established a secure development lifecycle for future device iterations.
