Computer security control module and safeguard control method thereof

Abstract

The computer safety control module includes CPU, memory connected to the CPU, connector, safety coprocessor, IDE controller, SCSI controller and identity authority identifier. The computer safety protecting control method includes: starting self-test with the safety module in the computer, alarming and waiting for the user to process in case of abnormality found in the self-test, and initiating BIOS program with the computer system unit to initialize the computer; calling computer safety control module PCI to expand ROM and to turn off the unsafe peripheral; performing user authority identification with the user's authority identifier; starting the hardware units based on the authority; entering the computer operation system, monitoring the system unit state and reporting regularly to the safety control module with the background monitoring program, and performing safety processing with the safety control module in case of illegal operation, etc.

Description

technical field [0001] The invention relates to a computer safety control module and a safety protection control method thereof, in particular to an embedded computer safety control module based on a PCI bus interface and a safety protection control method thereof. Background technique [0002] With the development of the times, the use of computers is very common, so the dependence on computers is getting stronger and stronger. Once the computer has a problem, it will be very serious and fatal, so ensuring the safety of the computer is becoming more and more important. There are many existing computer security devices, including hardware security devices and security software. [0003] However, the existing security equipment has the following shortcomings: [0004] First, the existing security equipment only solves a certain aspect of security issues. Therefore, a systematic and complete solution to computer security issues requires the simultaneous use of multiple secur...

Problems solved by technology

However, the interconnection and interaction between these security devices is very difficult, and even if the linkage of these security devices is realized, this loosely coupled structure will inevitably reduce the security of the entire system; The complexity of unified management greatly reduces the ease of use

[0005] Second, the existing security equipment lacks the monitoring and control of the protected computer host system

For example, a firewall device can ensure that the network channel connected to the firewall on the computer is protected, but when this computer starts another network channel (such as dial-up, wireless network card, USB interface network card) and is not connected to the Internet through the firewall, then the network channel on this computer Cyber ​​Security Gets Out of Control

The firewall...
