Public network communication security monitoring system and method

Abstract

The invention discloses a public network communication security monitoring system and method. The system comprises a physical layer module used for monitoring a network hardware entity, an execution layer module, a control system, a scheduling layer module and an interaction layer module. The probe working method comprises the following steps: capturing a data packet passively captured and accessed to a network of the safety monitoring system and identified by a flow probe through a data packet capturing module; the flow table maintenance module converts the data packet into a data packet dataflow according to a specific rule; protocol and application identification of network flow of a source IP pair and a destination IP pair of the data packet data flow and basic flow statistics and analysis are completed through a decoding module and an identification module; protocol and service performance measurement of data packet data flow is completed through the performance analysis module,known, credible and visual management of public network rental resources and operation states of the public network rental resources is achieved, the public network communication service guarantee capability is improved, and a technical support platform is provided for operation management and evaluation of the public network resources.

Description

technical field [0001] The invention relates to the technical field of electric power communication, in particular to a public network communication security monitoring system and method. Background technique [0002] At present, public network communication is widely used in emergency communication, Internet access, remote meter reading, mobile office and other fields of power communication, and has become an important part of power communication network, playing an important role in power grid production and enterprise management. With the development of smart grid, the application scale of public network communication will be further expanded, but grid users lack effective platform support for the management of large-scale public network communication security and service assurance, and the following problems exist: [0003] There are security risks in the use of public network wireless channels such as GPRS. Attackers can intercept and imitate signals to miscontrol power...

AI Technical Summary

Problems solved by technology

[0003] There are security risks in the use of public network wireless channels such as GPRS. Attackers can intercept and imitate signals to miscontrol power grid equipment, causing power grid accidents, and becoming a shortcoming in the security of the entire power communication network, affecting public safety. How to use technical means Monitoring public network behavior has become a difficulty in public network management;

[0004] Lack of effective means of communication monitoring and fault location, communication faults cannot be found in time, the location of the fault cannot be accurately located, and it is difficult to judge whether the power grid device or the operator’s channel is faulty, resulting in unclear responsibilities of both parties, mutual prevarication and delay of fault processing, or simultaneous processing, and frequent on-site, inefficient
