With the gradual deepening of the digital transformation of enterprises, the business development of enterprises depends more and more on the increasing office, production, R & D and other IT systems, and more and more frequently need to exchange a large number of data with the outside.

In the day-to-day business of an enterprise, there are a large number of scenarios that require file transfer between different networks:

Employees in the intranet need to send design drawings, project materials and other documents to the users of the extranet. Customers, suppliers and partners need to send files to intranet employees through the Internet. Scientific and technological enterprises need to continuously import a large amount of data obtained from the outside into the R & D network for data processing such as machine learning, data mining and so on, such as data collected by sensors, test data and network services.

The physical isolation of the network brings a lot of inconvenience to data exchange. for example, employees can only access the Internet when they travel, and there is no way to obtain intranet files. In addition, the internal network service system needs to extract and collect data from the external network, because of service isolation, data acquisition is also very difficult. Therefore, with the increasing maturity of enterprise IT business systems, the demand for controllable cross-network data exchange is becoming stronger and stronger.

At present, enterprises mainly adopt the following ways to solve the problem of cross-network file transfer.

(1) copy data between internal and external networks by moving hard disk

Within the enterprise, there are generally restrictions on the use of USB disk / mobile hard disk, so it is generally designated that a small number of people with authority, often the IT department, are responsible for copying data between inside and outside by moving the hard disk in accordance with the requirements of the business department.

However, with the increasing amount of data that needs to be transmitted between networks and the increasing frequency, IT departments are often overwhelmed, and often suffer complaints from business departments about data copying in time, data errors and so on. At the same time, because the data copy is done manually, it is difficult to regulate the scope of the content copied, and it is more prone to errors in this process.

(2) move files between internal and external networks through FTP or network sharing

When the enterprise internal and external network is isolated through the firewall and other logical means, the enterprise may set up a FTP server or network share, set it as an exception in the network equipment, so as to achieve the internal and external network file movement.

In this way, on the one hand, it opens a special case of "security isolation policy", and the security of network isolation is greatly reduced, on the other hand, it still needs to be managed and implemented by special personnel, which can not solve the problems caused by manual processing. At the same time, when uploading and downloading a large number of files through FTP and other means, the phenomenon of error interruption may often occur, which requires continuous tracking of human resources.

(3) carrying out inter-network file ferry through the network gate

Generally, the network gate will have the built-in file ferry synchronization function, and the user can set the storage location specified by the internal and external network, and the network gate can realize the file synchronization.

However, the network gate can only solve the problem of physical location movement of files, and it is difficult for enterprises to specifically control which files can be synchronized, who has the authority to operate, and how to deal with the files after synchronization. This way can not complete a complete chain of specific business.

(4) Internal and external network double enterprise network disk + network gate ferry

In fact, this method is based on the physical movement of files, superimposed the file management, easy access and other features of the network disk, because to build two sets of private network disks, the implementation cost will be greatly increased.

Using this dual-end synchronization method, it is often possible to have some loopholes in business processes, and can not effectively address the needs of scenarios such as "sending data to external customers". In addition, the private network disk is generally oriented to the type of office documents, and often does not have the ability to send a large amount of business data.

(5) the solution of secure file exchange between Ftrans internal and external network

Ftrans internal and external network file security exchange solution, it is a digital package-based secure file exchange solution, can achieve full-chain, high-performance, automated cross-network two-way data transmission.

It can support the cross-network data transmission security requirements of "computer information system security protection level" from level 1 to level 5, including intermediate security standards with firewalls and DMZ zones as the main isolation means, and advanced security standards with network gates, optical gates and optical disc ferries as isolation means. At the same time, it has a fully automated cross-network data transmission mechanism, high-performance internal and external network file exchange of large amounts of data, full chain service and visual tracking of internal and external network file exchange.
