Secure access terminal for intranet and extranet

Abstract

The invention provides a secure access terminal for an intranet and an extranet. The secure access terminal comprises intranet and extranet safety equipment and a processing unit, wherein an input-end interface unit of the intranet and extranet safety equipment is connected with a first control unit and a second control unit respectively through a two-channel switch unit; when a client selects an extranet mode, the processing unit controls the two-channel switch unit to gate the second control unit, switches on a second power control switch to enter an extranet system and switches off a first power control switch to cut off connection with an intranet system at the moment; and when the client selects an intranet mode, the processing unit controls the two-channel switch unit to gate the first control unit, switches on the first power control switch to enter the intranet system and switches off the second power control switch to cut off connection with the extranet system at the moment. The secure access terminal for the intranet and the extranet is used for realizing isolation and safety protection of the intranet and extranet systems, and information security of the intranet system can be protected effectively.

Description

technical field [0001] The invention relates to the Internet field, in particular to an internal and external network security access terminal. Background technique [0002] With the rapid development of the Internet (Internet), it has become an irreversible trend for various agencies, enterprises and institutions to use the Internet to carry out their work. In recent years, with the development of "enterprise Internet access" and "government Internet access" projects, especially the construction of "e-government" systems, a large number of computers in various units and departments have been connected to the Internet through various methods. However, since the Internet is an open network system, any computer connected to the Internet may be attacked by hackers, and the information stored in the computer may be stolen or tampered with. In addition, the Internet is also the main way for computer viruses to spread. At present, the core technologies of common security technol...

AI Technical Summary

Problems solved by technology

[0011] The internal integrated wiring of the enterprise should establish a physical structure of internal and external dual networks, and the switching equipment should also provide internal and external dual copies. The internal network data is stored on the local disk, and the data is not safe.

[0012] Network security can be realized, but during the implementation process, the engineering cost and equipment cost are high, the technical service volume is large, and the system maintenance is cumbersome
