Method and device for early warning based on website traffic analysis

Abstract

The invention provides an analysis and early warning method and d based on website traffic. The analysis and early warning method based on the website traffic comprises steps of obtaining website traffic of a monitored website in a target time frame, performing curve fitting on website traffic distribution which corresponds to the target time frame and is drawn according to the website traffic to obtain a practical distribution curve, determining whether a curve deviation between a practical distribution curve and a reference distribution curve corresponding to the target time frame satisfies a preset condition, wherein the reference distribution curve is determined according to the website traffic corresponding to the target time frame according to the history record, and using a preset encrypted channel to sent flow abnormity early warning information when the curve deviation between a practical distribution curve graph and a reference distribution curve graph satisfies a preset condition. The analysis and early warning method based on website traffic can improve analysis early warning accuracy.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an early warning method and device based on website traffic analysis. Background technique [0002] With the popularity of the Internet, the network has become inseparable from people's lives. However, while the Internet brings great convenience to people's lives, it also brings some security problems. For example, in large-scale network attacks, the initiator uploads some attack scripts through the network, and the network spreads quickly and widely. Develop a large-scale distributed denial of service (Distributed Denial of Service, DDOS) attack, causing the website server that received the offensive script to be paralyzed. Therefore, it is very necessary to analyze and warn the website traffic. [0003] At present, the existing website traffic analysis and early warning system reflects the trend of website traffic through traffic statistics, but because the websi...
