A method of protecting computer data security

Abstract

The invention discloses a computer data security control device. The computer data security control device comprises a microprocessor, relay drive parts, a computer power source control relay, a computer network control relay, a computer power source, a double-pole-double-throw switch, computer hard disks, interface conversion parts, a network card and a computer network hub. The relay drive parts comprise a first relay drive part and a second relay drive part. The computer hard disks comprise a secrecy hard disk and a common computer hard disk. The interface conversion parts comprise a first interface conversion part and a second interface conversion part. As the microprocessor is adopted for controlling a relay driver, information safety protection of the hard disks of a computer and safety protection after the computer is networked are effectively achieved, the optimal control combination is achieved, the computer data security control device is simple in structure, low in cost and easy to popularize, the control method is high in sensitivity, and once an alien invader enters, the computer data security control device immediately stops the alien invader from entering.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for protecting computer data security. Background technique [0002] With the rapid development of computer technology and network, computer has become an indispensable tool in people's work, life and study. Similarly, the development of computer networks has also brought security risks to users' computer information. Network information theft, information attacks, and virus transmission all exist and develop all the time. At present, in order to solve the data information security problem of the user's computer, people have adopted many measures and methods, one is to adopt isolation card technology; There are problems. Some hackers are easy to invade the computer system and steal the data information inside the computer, causing certain losses to people. At present, changes in the system software or hardware environment that the existing security control system reli...

Similarly, the development of computer networks has also brought security risks to users' computer information. Network information theft, information attacks, and virus transmission all exist and develop all the time.

At present, in order to solve the data information security problem of the user's computer, people have adopted many measures and methods, one is to adopt isolation card technology; There are problems. Some hackers are easy to invade the computer system and steal the data information inside the computer, causing certain losses to people. At present, changes in the system software or hardware environment that the existing security control system relies on will also affect the security of the system. Constitute a direct threat, resulting in the possibility of information leakage
