Problems solved by technology

From a technical point of view, as long as the computer is connected to the Internet and the hard disk is powered on, "network hackers" can change the working mode of the user's computer from the Internet, and there is no technical measure that cannot be taken to steal user information. Neither protective measures nor measures can guarantee the absolute security of user computer information

Description

Technical field: [0001] The invention relates to the improvement of computer hardware structure, especially belongs to the field of computer network security. Background technique: [0002] With the continuous expansion of the scale of computer networks, the contradictions of computer information security issues have become increasingly prominent. On the issue of computer network security protection, there are many technologies and methods adopted in the society at present. One is to use the isolation card technology, and use the system software to control the isolation card to select two different hard disks; the other is to use two different operating systems for the computer. Control two hard disks; the third is to divide one hard disk into two different work areas and use two different operating systems for control; the fourth is to use dual computers, one connected to the Internet and one not connected to the Internet; the fifth is to use the Internet No matter what ki...
