Critical Infrastructure: Why IoT Firmware Security Matters

The firmware that runs in any IoT module is complex yet often overlooked. Everything that makes devices smart goes through this module. As such, it’s on the front line of your IoT device’s security. However, most device manufacturers don’t know what the firmware is doing or who wrote it.This firmware is responsible for many tasks, including: 

• The communication technology protocols  
• An application interface that gives control and notifications about module behavior 
• Device security 

It’s easy to dismiss modules as a simple radio or wire. However, IoT is evolving. Modules require special features (e.g., security features to mitigate threats) and resources to support various use cases, If your IoT modules don’t come from a trusted provider, devices like smart meters can be compromised. Unsecured modules leave the door open for hackers and other bad actors. Security breaches in critical infrastructure devices can have catastrophic consequences.
