Data ferrying system and method

Abstract

The invention discloses a data ferrying system and method. The method comprises the steps that a flow probe obtains network flow data of an external network; the log collector collects a network security log of an external network, and analyzes the network security log according to a log analysis rule; the external network server converts the network flow data and the analyzed network security log into a text format and encrypts the text format; the isolation device transmits the encrypted network traffic data in the text format and the network security log to an intranet server; the intranet server decrypts the encrypted network traffic data and the network security log in the text format; and the situation awareness and security operation platform performs network security analysis and alarm of the extranet according to the decrypted network traffic data and the network security log, so that secure transmission of the extranet traffic data to the intranet is realized, potential safety hazards of the extranet traffic data can be pre-warned, and the dual requirements of intranet network security and flow data transmission are met.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data ferry system and method. Background technique [0002] Due to the threat of security intrusion in the network connection between the enterprise intranet and the enterprise extranet, devices such as gatekeepers are added between the enterprise intranet and the extranet to isolate different networks. However, after the network is isolated, a network connection cannot be established between the internal and external networks, and only simple file transfers can be realized based on the gatekeeper device, which cannot meet the traffic transmission in the big data scenario. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] An embodiment of the present invention provides a data ferry system for realizing secure transmission of traffic data between an internal network and an external network. The system incl...
