SYSTEM AND METHOD FOR SECURITY CONTROL OF OPERATING SYSTEM

摘要

A system and method for performing security control of the OS (operating system). The system includes a primary OS module, a system isolation module, a data isolation module and a security control module, a secondary OS module is deleted and installed then booted, and a dynamic data is copied to a disk protect partition by the system. The method comprises reading a startup message of the primary OS module and comparing it with the standard information. And it also comprises setting up the secondary OS and loading the primary module and secondary module if the result of the comparing is "yes", otherwise repairing the startup message of the primary OS module with the standard information. The malicious destroy of the computer core is prevented and the security of the current OS environment is protected by the system and method of the invention. Using the method of data isolation ensures the integrality of the data, and using the method of the system isolation ensures the whole system would not be affected because of the factor of insecurity of a certain OS.
