A network access control method and system for a securely controlled terminal

Abstract

The invention discloses a network access control method of a security-controlled terminal. The method is implemented based on a system, the system includes a terminal device and a security module, and the method includes the following steps: Step S1, the terminal device logs in to the security module; step S2, the terminal device establishes network communication with the security module; step S3, the security module performs identity verification on the terminal device, and executes step S4 after successful verification; step S4, the terminal device acquires a network address, And set the local network address as the obtained network address; step S5, the terminal device is connected to the network. The present invention realizes the sharing of maintenance and debugging interfaces among various businesses, minimizes the number of required maintenance and debugging interfaces, further improves the convenience and efficiency of various business maintenance and debugging personnel, and reduces the cost of various business maintenance and debugging work. And effectively guarantee the security of various services without interfering with each other.

Description

technical field [0001] The present invention relates to a terminal network access method, in particular to a security controlled terminal network access control method and system. Background technique [0002] With the rapid development and popularization of the network, the network function is becoming more and more powerful, and the phenomenon of multi-service sharing network is becoming more and more frequent; the security between various services is getting more and more attention, and different VLANs are generally used to realize the isolation of business applications. Maximize the isolation of various services of the shared network from each other, so as to achieve the effect of non-interference between various services; [0003] However, in the process of sharing the network according to various services, dividing the network into different VLANs brings another problem, that is, the isolation and authorization of maintenance and debugging. Reserving debugging interfa...

Problems solved by technology

[0003] However, in the process of sharing the network according to various services, dividing the network into different VLANs brings another problem, that is, the isolation and authorization of maintenance and debugging. Reserve the debugging interface, this method wastes the interface, and the security of the reserved debugging and maintenance interface cannot be guaranteed, and the reserved debugging and maintenance interfaces are many and not universal, which will bring great inconvenience to the specific maintenance and debugging work in the future

[0004] In the existing network, according to the debugging and maintenance needs of various services, a certain debugging and maintenance interface is reserved correspondingly according to the type of business. Since not every kind of business is required for debugging and maintenance at the same time, this technical solution brings great The waste of interfaces also brings great inconvenience to the maintenance and debugging personnel of various businesses. It is easy to make mistakes in the specific corresponding interfaces, resulting in high maintenance and debugging costs, and may even lead to certain access security risks.
