CRNET (China Railcom Net) sSafe cooperative defense system for whole course communication network

Abstract

The invention discloses a CRNET (China Railcom Net) safe cooperative defense system for a whole course communication network, comprising a safety analysis control center, cooperative defense devices arranged at the key parts of various network nodes and a flow data detection subsystem arranged at an outer port of the network nodes. wWherein each cooperative defense device is internally provided with a flow monitoring function unitcomponent, the cooperative defense function unitcomponent and a plurality of safety function unitcomponents, such as a fireproof wall, the flow monitoring function component unit is used for informing, receiving, analyzing and processing a data flow collected by a detection system, the cooperative defense function unitcomponent is used for generating or receiving a strategy submitted by the safety analysis control center and implementing safe management and control according to the strategy, the safety analysis control center is used for integrally configuring, monitoring and managing the plurality of presidial cooperative defense devices, and the flow data detection subsystem is used for collecting the data flows of the preliminarily entering network nodes pre-entering the network. The invention can flexibly configure according to practical use, establishes a multi-level network safety strategy control system based on the safety analysis control center, the cooperative defense devices and the flow data detection subsystems for global network safety defense and management and effectively improves the whole safety defense strength and the management flexibility of thea network.

Description

【Technical field】 [0001] The invention relates to the technical field of Internet and computer network security, in particular to a network collaborative defense security system for computer network security integration and collaborative defense. 【Background technique】 [0002] The rapid development of computer networks has brought great convenience to people's production and life, and has rapidly improved the informatization level of various industries and enterprises. While benefiting from the huge opportunities brought about by the rapid development of computer networks, we also have to face the challenges of various network security issues: viruses, worms, Trojan horses, malicious attacks, unauthorized access, illegal outreach, garbage mail etc. These network security threats not only bring great inconvenience and loss to individuals' work and life, but also have a huge impact on enterprises and governments. [0003] In the face of these threats, people have proposed a...
