Abstract

The network safety control equipment based on physical isolation and data exchange monitoring includes main controller, power supply controller, network controller and fixed disc controller. The output of the main controller is connected to the power supply controller, the network controller and the fixed disc controller. The equipment is connected to double-fixed disc computer to protect important data alone. Physically, the present invention can avoid the attack from the network completely and prevent virus invasion effectively to ensure the computer safety in data storage and log-in with the network. At the same time, the fixed disc controller monitors and isolates according to the protocol to realize the mono-way data transmission and exchange safety between two fixed discs.

Description

Technical field: [0001] The invention relates to a computer network security device, in particular to a network security control device based on physical isolation and data exchange monitoring. Background technique: [0002] In the 1960s, people connected several computers to realize information transmission between computers, which changed the past where computers could only be used as pure data processing machines. People can communicate with each other or obtain information conveniently and quickly through computer networking. Especially with the rapid development of computer communication and network technology in recent years, and the implementation of the "Government Internet Project", human society has gradually entered a rapidly changing information age, and computer networks have become the most important means for people to communicate with each other and obtain information . However, when people obtain information, how to prevent the invasion of computer viruses...
