Description
Technical Field
The utility model relates to a network security field especially relates to a data security ferry-boat equipment.
Background
At present, in many fields, such as governments and military, high requirements on network security are required, and physical isolation between an internal network and an external network is required. Data transmission is carried out between two physically isolated networks, and a data ferrying method can only be adopted, namely, data in one network is transmitted to a ferrying memory, and then the data in the memory is transmitted to the other network. The data are respectively ferried from the outside to the inside and from the outside to the inside, and the ferrying cannot be carried out simultaneously, so that the efficiency of data safety ferrying is greatly reduced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a data safety ferry-boat equipment solves among the prior art data from the outside to inside and from the outside to the inside condition and will ferry-boat respectively, can not go on simultaneously, very big reduction the technical problem of the efficiency of data safety ferry-boat.
The utility model aims at realizing through the following technical scheme:
a data security ferry device, comprising: the ferry server is provided with four network interfaces and a USB interface, the first network interface of the ferry server is connected with an intranet through the first unidirectional network gate, the second network interface of the ferry server is directly connected with an extranet, the third network interface of the ferry server is connected with the extranet through the second unidirectional network gate, the fourth network interface of the ferry server is directly connected with the intranet, the USB interface of the ferry server is connected with the virus scanning end, and the virus scanning end is controlled by the management terminal connected with the virus scanning end.
The technical effects of the utility model are that:
the utility model discloses can carry out the two-way data safety ferry-boat of intranet and extranet simultaneously to have perfect virus scanning function, the security performance improves greatly.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive labor.
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1, for the utility model discloses a data safety ferry-boat equipment that embodiment provided includes: the ferry server is provided with four network interfaces and a USB interface, the first network interface of the ferry server is connected with an intranet through the first unidirectional network gate, the second network interface of the ferry server is directly connected with an extranet, the third network interface of the ferry server is connected with the extranet through the second unidirectional network gate, the fourth network interface of the ferry server is directly connected with the intranet, the USB interface of the ferry server is connected with the virus scanning end, and the virus scanning end is controlled by the management terminal connected with the virus scanning end.
Wherein, the virus scanning end is connected with the virus library server. And the virus library is updated regularly through the virus library server so as to discover the security risk and the system vulnerability in the transmission process in time. And can issue scanning strategy and processing rule through control terminal.
The ferry server comprises a microcomputer mainboard, a CPU chip, a hard disk and a memory, wherein the CPU chip, the hard disk and the memory are arranged on the microcomputer mainboard, and the microcomputer mainboard is provided with a first network interface, a second network interface, a third network interface, a fourth network interface and a USB interface. The memory can be used as a cache for data transmission, for small data transmission, for example, data smaller than 16G, the memory of 16G can be directly used for caching, so that transmission efficiency is improved, and for large data (larger than 16G), the data can be transferred by means of a hard disk.
In order to further improve the transmission efficiency and reduce the size of the device, the first unidirectional network gate and the second unidirectional network gate can be replaced by an integrated unidirectional transmission card with a PCIE interface, and the integrated unidirectional transmission card is inserted into a PCIE slot on the microcomputer motherboard.
The technical effects of the utility model are that:
the utility model discloses can carry out the two-way data safety ferry-boat of intranet and extranet simultaneously to have perfect virus scanning function, the security performance improves greatly.
It will be appreciated that the system architecture shown in the figures does not constitute a limitation on the system, and may include more or fewer devices than shown, or some devices in combination, or a different arrangement of devices.
The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, and all should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
