Computer protection apparatus and method

Abstract

The present invention provides a computer protection apparatus and method. The apparatus comprises: a policy management unit, a hardware measurement unit, a software measurement unit and an execution unit, wherein the policy management unit is used for configuring a to-be-measured hardware device and a to-be-measured kernel file according to received policy configuration information; the hardware measurement unit is used for measuring the to-be-measured hardware device when a computer powered on to obtain a first measurement value; the software measurement unit is used for measuring the to-be-measured kernel file to obtain a second measurement value; and the execution unit is used for determining whether the first measurement and the second measurement value are the same as corresponding standard measurement values, if yes, the to-be-measured hardware device or a guiding operating system is allowed to be started, and if not, after a starting privileged code from the outside is received or a warning message is sent to the outside, the to-be-measured hardware device or the guiding operating system is allowed to be started. The scheme provided by the present invention can improve the security of a computer.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a computer protection device and method. Background technique [0002] With the continuous development of computer technology, computers are playing an increasingly important role in life and production, and are widely used in hospitals, institutions, and enterprises. Various user data are stored in the computer, especially a large amount of data is stored in the server. These data may be the user's personal privacy, corporate business secrets, or government department confidential documents. If these data are obtained by illegal users, it will lead to personal privacy. Leakage, corporate business secrets are obtained by competitors, and important national decisions are made public, which brings troubles to individual users, causes huge economic losses to companies, and affects national security and social stability. In order to protect these important data, it is necessary to...

Problems solved by technology

[0004] In view of the prior art method of protecting computers through anti-virus or anti-malicious attack software, the computer is only protected at the operating system level, and the potential safety hazards existing at the bottom layer of the operating system cannot be protected, so the security of the computer is relatively low
