The main functions of one-way file transmission of the security isolation and information import system include supporting the transmission of a large number of small files and large files, supporting the strategy of renaming, supporting multi-level directory nesting, and supporting file format checking and virus killing independent of file extension.
In order to improve the reliability of file transmission, the one-way file transmission system provides a set of functions to accurately locate whether the file is correctly transmitted to the destination, which can help users determine the lost file conveniently and quickly and retransmit the lost file. Security isolation and one-way information import system One-way database synchronization provides one-way synchronization of commonly used databases such as ORACLE, SYBASE, DB2 and MS SQLSERVER. Support synchronization between the same database or heterogeneous databases, granularity to field level synchronization and special condition synchronization.
Because there is no information feedback in the system of security isolation and one-way information import, in order to improve the reliability of one-way database synchronization, one-way database synchronization has designed a set of functions to accurately locate whether the data is correctly imported into the destination, which can help users determine whether the data is lost and retransmit the lost data conveniently and quickly to ensure the integrity of user data.
One-way database is convenient for synchronous deployment, and can be seamlessly integrated with system and customer databases, that is, users can realize one-way synchronization without modifying any environment of the database. One-way database synchronization can basically achieve real-time synchronization in performance and meet customer needs. The one-way mail transmission function of the security isolation and information one-way import system provides stable and efficient one-way mail import and mail filtering functions.
One-way mail import function provides one-way mail transmission function from external network to internal network. Efficient mail transmission can support the daily application requirements of most application environments. In addition, the one-way mail transmission module will record the relevant information of each email to ensure the reliability of the one-way mail import function to the greatest extent.
Email filtering functions include email address filtering, email domain name filtering, email content filtering, email attachment filtering and ip address port filtering. Omni-directional mail filtering function can ensure that harmful and sensitive information cannot be imported into internal application systems to the maximum extent.
The convenience of product deployment was considered at the beginning of the design of one-way mail transmission function. When deploying the one-way mail import system, users only need to deploy the system between the original external mail server and the internal mail server, and specify the mail gateway of the relevant server, without migrating user data on a large scale.
