Abstract

The invention discloses a system proceed safe test for computer BIOS firmware and method, which comprises the following steps: initializing; proceeding BIOS sampling; analyzing BIOS image file; scanning various hidden dangers of BIOS; measuring completeness integrity of BIOS code; outputting the testing effect; proceeding safe repair for BIOS. This invention can decrease, reduce and remove safety loophole and hidden danger of computer BIOS, which provides reliable terminal safety prevention and overall protection for computer and network.

Description

technical field [0001] The invention relates to computer safety risk detection technology, in particular to a system and method for computer BIOS firmware safety risk detection. According to the detection principle of the present invention, the potential safety hazards existing in the current computer BIOS can be detected, and the detection results can be obtained by measuring the integrity of the BIOS code, and the computer BIOS can be safely repaired accordingly, so that it can effectively prevent computer BIOS from being targeted. Cyber ​​attack and information leakage. Background technique [0002] Computer BIOS (Basic Input / Output System) is a software system solidified in the computer motherboard chip, also known as firmware (firmware). After the computer is turned on and powered on, it first executes BIOS instructions to complete the detection and initialization of basic hardware and peripheral devices, loads the services provided by the system when it is running, an...
