FIRMWARE-LEVEL SECURITY AGENT SUPPORTING OPERATING SYSTEM-LEVEL SECURITY IN COMPUTER SYSTEM

摘要

A kind of pre-OS security agents run on environment independently of operating system (OS) but can exchange with the file system of interface microcontroller and with them on the OS of information security operation. Before OS startings, instruction state or situation are obtained, and being related to risk cannot operate normally safely, or influence starting OS with the variation of computer system. Based on the instruction, one group determines one or more movement analysis state situations. The pre-OS security agents execute the group one or more action response in the instruction.
