Embodiment

[0084] The present invention will be described in detail below through specific embodiments and accompanying drawings.

[0085] The system based on the method of the invention is composed of flow collection, frequency spectrum structure, drawing and display modules. The specific implementation and application of each module are as follows:

[0086] (1) Traffic collection: through hardware network devices integrated with security function chips, under the control of network traffic security policies, collect traffic information in the entire network environment with a fixed network traffic sampling cycle;

[0087] (2) Spectrum structure: extract the network security characteristic parameters that represent the network security and health degree, and assign different weight coefficients to the network security characteristic parameters according to their decisive role and influence degree on the network security and health degree, and perform normalization Process and construct...

Abstract

The network security monitor method based on network life frequency spectrum comprises: with fixed network-flow sampling period, collecting network flow, extracting network security eigen parameter and normalizing to form a network life spectrum representing network security and healthy level vividly. This invention is real time and dynamic, and provides reference and support for management decision.

Description

technical field [0001] The invention relates to a network security monitoring method based on network vital spectrum, and proposes a network vital spectrum representing network security and health, belonging to the field of computer network security. Background technique [0002] With the construction of information technology and the popularization of network applications, network security issues have encountered new severe challenges - DoS / DDoS attacks, large-scale outbreaks of worms, large amounts of spam that are difficult to suppress, and wanton flooding of various P2P video / voice downloads Abnormal network traffic generated by such applications seriously affects the network speed of the local area network and information applications, leading to large-scale network interruptions, a large waste of resources and hundreds of millions of economic losses. Although various security devices and products such as firewalls, IDS / IPS, and anti-viruses have been deployed in the ne...
