Security verification method during kernel operation of operation system

Abstract

The invention provides a security verification method during kernel operation of an operation system. The security verification method comprises the following steps that the validity of all kernel module files of a target operation system is confirmed, the validity of loaded modules in a kernel is verified, the validity verification is carried out on a new kernel module loaded at any time, all entrances switched from the user grade to the privilege grade in a processor are set again, each instruction to be translated required by the binary translation is checked, and the like. The method can be used for computer security software and can be used for fundamentally detecting the computer operation system in the operation for detecting kernel viruses existing in the computer operation system, in addition, the precaution can be carried out on the existing operation system for finding the kernel viruses tried to invade a computer, and in addition, viruses are conditionally cleared. The method belongs to a measure for thoroughly solving the problem of rootkit.

Description

technical field

[0001] The invention relates to the field of computer security, in particular to related technologies for detecting, preventing and clearing computer operating system kernel viruses and ensuring the safe operation of the operating system kernel. Background technique

[0002] Existing computer information security includes many aspects. Among them, the detection and prevention of malicious programs such as viruses and Trojan horses is an important part of computer security. Among them, viruses that run on the kernel level (kernel level) of the computer operating system and use the technology called rootkit have the highest technical content among computer viruses and are the most difficult to detect, prevent and remove.

[0003] A kernel virus refers to a virus that runs at the kernel layer of a computer operating system. The technology that makes viruses run on the kernel layer of the computer operating system is called rootkit technology.
