IoT Firmware
Noun · Security & Infosec
Definitions
The low-level software running on internet-connected embedded devices such as smart cameras, sensors, locks, or appliances. IoT firmware is a major security concern because it often controls update trust, local services, credentials, and hardware interfaces in devices with long support lifecycles.
In plain English: The built-in software that runs an internet-connected device.
Example: "The researchers extracted the IoT firmware and found hardcoded credentials plus an unsigned update path."
