What is firmware?
Firmware is the foundational software image embedded into a device that enables its hardware and operating system to function. It initializes hardware components, manages low-level device operations, and provides the runtime environment required for the operating system and bundled system components to execute. Firmware typically includes the bootloader, kernel, device drivers, and core system services, along with manufacturer-specific modifications and integrations.
Unlike regular applications, firmware runs with the highest level of privilege and operates below the user interface layer, making it critical to device stability, performance, and security. Because firmware controls how hardware and software interact, vulnerabilities in firmware can expose sensitive data, enable unauthorized access, or allow attackers to compromise the entire device. Firmware is usually installed during manufacturing or system updates and is not easily modified by end users, which makes rigorous security testing essential before devices are distributed.
