Computer information security system

Abstract

The invention provides a computer information security system. A computer main-board is connected with a computer peripheral, a user authentication controller is used for verifying whether user information has a legal identity, and a network security module is used for identifying and judging whether a network is safe; a port security control module is used for controlling an external interface of a computer system is opened to the outside world, an information tracking module is used for visiting, recording and tracking information visited and downloaded by the computer system, and an electromagnetic shielding anti-interference module is used for preventing electromagnetic leakage to cause classified information leakage. According to the system provided by the invention, the user authentication controller, a network information security module, the port security control module, the information racking module, the electromagnetic shielding anti-interference module and a data back-up module can be arranged to monitor and protect the information of the computer information security system from multiple angles and multiple aspects, therefore the security performances of use and transmission of the computer information security can be improved.

Description

technical field [0001] The invention relates to a computer system, in particular to a computer information security system, which belongs to the field of computer and information technology. Background technique [0002] Computers and computer networks have become important information carriers and transmission channels for enterprises, governments and various other organizations, greatly improving work efficiency and enabling the storage and processing of massive information. Computers and computer networks have brought great convenience to people's work and life, but there have also emerged information security issues that have attracted widespread attention. The reason why digital information security has attracted more attention than traditional data file security is that, on the one hand, digital information itself has the characteristics of being easy to copy.

The reason why digital information security has attracted more attention than traditional data file security is that, on the one hand, digital information itself has the characteristics of being easy to copy. With this characteristic, information is easily threatened by theft that is difficult to control and trace. On the other hand, Due to the remote information access function of the computer network, the information is vulnerable to the threat of destruction, alteration and theft
