Embodiment Construction

[0060] The specific implementation manners of the present application will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0061] figure 1 It is a schematic structural diagram of a message transmission system based on network isolation provided by an embodiment of this application, such as figure 1 As shown, the system at least includes: a first device 110 connected to a first network, a storage component 120, and a second device 130 connected to a second network.

[0062] The first network and the second network are two types of networks that require network isolation, for example: the first network is a public security network, and the second network is a video network; or, the first network is a public security network, and the second network is another type of independent network, this embodiment does not l...

Abstract

The invention relates to a message transmission method and device based on network isolation, a storage medium and a message transmission system based on network isolation, and belongs to the technical field of communication, and the method comprises the steps: receiving a cross-network transmission message of a user side accessing a first network to a second network, the cross-network transmission message carrying destination-side information and message contents; when a first communication connection between a first device and a preset storage component exists, sending the cross-network transmission message to the storage component for storage based on the first communication connection; disconnecting, by the storage component, the first communication connection and establishing a secondcommunication connection with a second device; reading, by the second device, the cross-network transmission message stored in the storage component based on the second communication connection, andsending the message content to a destination side indicated by the destination information through the second network. The problem of network intrusion or information leakage can be solved. Physical isolation of the first network and the second network is realized. Service processing can be realized. A message transmission process can be traced.

Description

technical field [0001] The present application relates to a message transmission method, device, storage medium and system based on network isolation, and belongs to the technical field of communication. Background technique [0002] Network isolation refers to the technology for two or more computers or networks to realize information exchange and resource sharing on the basis of disconnection. Common network isolation technologies include: firewalls, trusted boundaries, and gatekeepers. [0003] A firewall is a protective barrier constructed on the network boundary of the two networks that need to be isolated. The communication monitoring system set at the network boundary releases the access that has been admitted, thereby blocking network intrusions, attacks, etc., and achieving the isolation effect. However, the firewall cannot identify the application layer and is ineffective against attacks hidden in the application. The firewall can only reduce the access risk of un...
