Abstract
Description
Technical field
The present invention relates to a kind of switch and method, especially a kind of intelligent physical isolation safe switch and method.Belong to the data transfer of computer security fields.
Background technology
The fast development of computer technology, for the masses' work and life brought a lot of facilities, the especially development of Internet technology has thoroughly changed our life and behavioural habits.Develop into now, manage business on the computing machine by based on the mathematical operation of unit, cloud computing and the cloud service that file processing is transformed into Internet-based, extension of network progressively is formed on worldwide information sharing and business processing to external network internally.But, when offering convenience, information sharing also brings the risk of information leakage, intranet and extranet are connected when carrying out exchanges data, also brought the management test of information security, particularly in network attack and virus all in the very frequent and severe situation, if do not have safety precaution mechanism or strict Safety Management Measures, professional normal operation all is difficult to guarantee.
As everyone knows, according to relevant information safety management regulations, in some special industries or unit, maintaining secrecy and the referred very high status of safety of information do not allowed least bit mishap, and this point embodies the most obviously in the government affairs service.For example, China widelys popularize online government affairs with Improving Government work efficiency and masses' service satisfaction, it is convenient for the masses that governments at all levels unit all releases the government affairs service network, the front end of government affairs service network must be built at internet platform, masses' ability free access, but in order to guarantee data security, the operation system of units concerned can not directly externally connect again, the unit's of having to be erected at Intranet.Therefore, data just occur and how to exchange and guarantee a safe difficult problem at intranet and extranet.
It is reported that traditional safe isolation method mainly is to adopt gateway, but gateway but can't be realized physical isolation truly, has equally certain potential safety hazard.Accomplish safety isolation truly, must accomplish absolute physical isolation, make and do not carry out data by network communication mode between the intranet and extranet and directly exchange, thereby reduce the potential safety hazard that information leakage causes.Therefore, the most traditional mode is exactly to insert the outer net computer by tangible media such as artificial use USB flash disks, and data are copied into media such as USB flash disks, then extracts and inserts the Intranet computer again, copies into the Intranet computer just copying into the data of USB flash disk.But, although this kind manual method has realized the physical isolation of absolute sense, but still be difficult to thoroughly get rid of the potential safety hazard of intranet and extranet exchanges data, and adopt manual mode of operation's cost larger, inefficiency, make easily operating personnel tired and cause the appearance of misoperation, but also easily by the premeditated incorrect data of transmission of people and virus, bring information security hidden danger.So, need a kind of novel inner-external network data safety switching equipment.
Summary of the invention
The objective of the invention is provides a kind of security that can guarantee the intranet and extranet exchanges data in order to solve the defective of above-mentioned prior art, the intelligent physical isolation safe switch that can increase work efficiency again.
Another object of the present invention is to provide a kind of intelligent physical isolation safe method for interchanging data.
Purpose of the present invention can reach by taking following technical scheme:
