An embedded project is a build that combines software and hardware to perform a dedicated function, such as controlling sensors, relays, displays, or communication links. Unlike general-purpose software, it runs on specific microcontrollers or boards and is shaped by tight limits on memory, power, timing, and physical interfaces.
In cyber security, embedded projects matter because they often become part of the attack surface. Weak firmware, unsafe update paths, exposed debug ports, and poorly secured peripherals can let an attacker alter behavior, steal data, or disrupt operation. Defenders also use embedded projects to build custom security tools, monitoring devices, and trusted hardware controls. When reviewing an embedded design, security teams look at code, circuitry, boot process, and external connections together, because a flaw in any layer can undermine the whole system.
