Multi-line parallel monitoring method based on internal and external network isolation

Abstract

The invention discloses a multi-line parallel monitoring method based on internal and external network isolation, and the method comprises the steps: S101, constructing a multi-line parallel monitoring unit for the real-time monitoring of a network, and enabling the multi-line parallel monitoring unit to monitor the change of a network protocol IP address of a network interface, the real-time flowof a network card, and the state of a network icon; S102, if it is detected that a network protocol IP address is changed, or network card real-time flow fluctuation violates a preset flow model, ora network icon is changed, it is judged that network connection is changed; S103, if it is judged that the network connection is changed, executing a corresponding security operation. According to theinvention, a program means is utilized, and when network abnormity (such as network IP change, Internet access monitoring and the like) occurs in a private network or a local area network, disconnection or shutdown processing with time less than 500 milliseconds is executed immediately according to a set program. Therefore, the safety protection of the private network is realized, and the seriousinfluence caused by disordered network cable insertion, network error change and the like is reduced.

Description

technical field [0001] The invention relates to the field of computer security, in particular to a multi-line parallel monitoring method based on the isolation of internal and external networks. Background technique [0002] Computers on the business private network are directly connected to the Internet or access the Internet through other networks, and private network equipment is directly connected to other networks without security protection and policy settings, which are illegal outreach. [0003] Illegal outreach leads to the connection between the business private network and the Internet, which brings serious security risks to the private network and violates the regulations on physical isolation between the private network and the Internet. [0004] However, in the existing network monitoring methods, people with ulterior motives can change the network settings of the computer in a very short period of time. In order to improve the speed of monitoring feedback and ...

[0004] However, in the existing network monitoring methods, people with ulterior motives can change the network settings of the computer in a very short period of time. In order to improve the speed of monitoring feedback and make the monitoring between the network and the user's computer more timely, a method to reduce the risk of illegal outreach
