Network service security access method, terminal, system and readable storage medium

Abstract

The present invention relates to the field of information security technology, and in particular to a LAN-based network service security access method, terminal, system and readable storage medium. The network service security access method includes: monitoring network communication data processing events based on the LAN, Then suspend execution of the processing event and analyze the identity information of the processing terminal corresponding to the processing event according to the MAC frame of the network communication data; key; according to the shared key and identity information, calculate randomized new identity information according to the preset calculation method, replace the identity information with the new identity information, let the network communication data carry the new identity information and continue to execute network communication data processing events, in order to realize The specific network service that should be disclosed is hidden from other users except the preset specific network service visitors, so as to achieve the purpose of safely accessing the specific network service.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a LAN-based network service security access method, terminal, system and computer-readable storage medium. Background technique [0002] In a local area network with high security requirements or special application scenarios, one or a part of the network nodes usually provide specific network services to other nodes that meet the requirements. For example, within an enterprise, only one computer in a certain department’s LAN provides data download services, and only computers on the network with download permissions can access the service; An export computer has the authority to access other regional networks, and it needs to summarize various monitoring data in the production environment in this region and transmit them to other regions. Therefore, the export computer needs to open a data service port in the internal network to allow the responsible monitor...

Problems solved by technology

On the other hand, this scheme to change the entire network topology is relatively complicated, which affects both the stability of the network and the efficiency of network services

And the beneficial effect 3 of its patent is described: "Users in the intranet can still use the static IP address to access specific terminals such as network printers and servers in the original way, while ensuring network security, it improves the intranet access to specific terminals. Access efficiency", as can be seen from the patent's description of its own beneficial effects, in this solution, access to specific network services provided by specific terminals is still more inclined to use static IP addresses to improve access efficiency, and there is no True Hide Protects ISPs
