Teaching computer network security control system

Abstract

The invention discloses a teaching computer network security control system. The system comprises a central processing unit (CPU), the CPU is connected with a normal hard disk, a network monitor and afault detection system; the CPU is connected with a relay through a relay driver, the relay is respectively connected with a network card and a secret hard disk; the network card is connected with anetwork selector switch, the network selector switch is connected with at least two network communication units connected with the internet; and a signal end of the network selector switch is connected with the CPU. The CPU is connected with the relay through the relay driver, the relay is respectively connected with the network card and the secret hard disk, when the relay is in work, one of thenetwork card or the secret hard disk is connected with the CPU; through the arrangement of the relay, the secret hard disk of the computer stops running under the networking state, thereby guaranteeing the security of the secret data of the user.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a teaching computer network security control system. Background technique [0002] With the development of network technology, computers are an indispensable tool in people's work, life and study. Computer networks have developed rapidly in various fields of society, including the field of educational equipment. Modern education is increasingly inseparable from digital equipment. Teaching Using computers to network to obtain educational resources, in the course of the operation of teaching computers, is inevitably subject to various attacks on the network, which brings hidden dangers to computer information security. In order to better monitor the network security operation of the computer network, it is often necessary to design a special control device. When the traditional control device detects unsafe factors, it often cannot quickly isolate and alarm, and the securi...

[0002] With the development of network technology, computers are an indispensable tool in people's work, life and study. Computer networks have developed rapidly in various fields of society, including the field of educational equipment. Modern education is increasingly inseparable from digital equipment. Teaching Using computers to network to obtain educational resources, during the operation of teaching computers, it is inevitable to suffer from various attacks on the network, which brings hidden dangers to computer information security

In order to better monitor the network security operation of the computer network, it is often necessary to design a special control device. When the traditional control device detects unsafe factors, it often cannot quickly isolate and alarm, and the security is low. Due to the teaching computer connection There are many teaching computers, once the teaching computers are poisoned or attacked, it is easy to cause a large number of teaching computers to be paralyzed, causing adverse consequences
