Network safety system and method

Abstract

The invention discloses a network safety system, including firewall arranged between internal network and external network and trustable node arranged between the firewall and the external network, and the firewall includes a first port inside the firewall and a second port outside the firewall, and the trustable node includes a media flow receiving port used to converge code flow transmitted between the trustable node and the second port. It realizes code flow convergence as the code flow is transmitted between the trustable node and the internal network, thus assuring the separation between the internal and external networks and simultaneously not increasing time delay of code flow.

Description

Technical field [0001] The invention relates to a network security technology in the field of electronics or communication, in particular to a network security system and method. Background technique [0002] In recent years, with the continuous increase in the number of Internet users, there have been more and more business applications based on IP (Internet Protocol) networks. However, while IP technology has become the mainstream technology for building network applications, it is inherently simple. The essential characteristics of openness and openness have not been fundamentally changed, which has left hidden dangers for the emergence of network security problems, especially for enterprise users. Due to the existence of the above-mentioned hidden dangers, it is very possible for commercial secrets to be transmitted on the Internet. Data becomes insecure due to malicious attacks by hackers. This situation is even more serious for users of financial companies such as banks, in...
