Firmware is the important foundation for computer security. The paper surveys threats to firmware, methods of detecting vulnerability and malicious code in firmware, and studies about secure firmware. Problems and drawbacks existing in security detecting and secure firmware are analyzed. Some fields worthy to be explored are put forward including improvement of accuracy and diversity about firmware security detection system, standardization of evaluating procedure and result of firmware security detecting, adding dynamic code certification and validation to secure firmware, adding data accessing protection to secure firmware.
