Soft isolation assembly for network access debugging and using method thereof

Abstract

The invention provides a soft isolation assembly for network access debugging and a using method thereof. A network monitoring module, an isolation control module and a link establishment and data forwarding module are included; the network monitoring module is responsible for monitoring a debugging port information network to access debugging port information and submitting client link establishment information and transmitted data to the isolation control module; the isolation control module analyzes the link information and the transmitted data and compares the information with a pre-configured authorized access condition, the network data belonging to an allowable access range are submitted to the link establishment and data forwarding module, and the network data not belonging to theallowable access range are blocked. In a condition of not changing a network structure and debugging object parameters, isolation, monitoring and control on a maintenance computer and a device are carried out when an operation and maintenance person accesses and debugs the device, device access by the operation and maintenance person in excess of authority and network attacks on the device by themaintenance computer can be avoided, and the safety operation of a substation network and the device is ensured.

Description

technical field [0001] The invention relates to the technical field of network debugging of substations and master stations, in particular to a soft isolation component for network access debugging and a method for using the same. Background technique [0002] At present, when the operation and maintenance personnel maintain and debug the network equipment such as measurement and control, protection and telecontrol of the operation of the substation, they usually directly connect the maintenance computer to the network switch of the substation to access and debug the target network equipment. The network structure of network access and debugging is as follows: figure 1 As shown, there is no isolation, access monitoring, and access control between the maintenance computer and the network equipment running in the substation. There is a risk of operation and maintenance personnel accessing other running network equipment without authorization, and there is also a risk that the m...

[0002] At present, when the operation and maintenance personnel maintain and debug the network equipment such as measurement and control, protection and telecontrol of the substation operation, they usually directly connect the maintenance computer to the network switch of the substation to access and debug the target network equipment. The network structure of network access and debugging is as follows: figure 1 As shown, there is no isolation, access monitoring, and access control between the maintenance computer and the network equipment running in the substation. There is a risk of operation and maintenance personnel accessing other running network equipment without authorization, and there is also a risk of maintenance computers carrying viruses or network attacks on running equipment.
