Problems solved by technology

[0002] The network is essential to us, but everything has a negative side. There will also be many obstacles when using the network, and the most difficult to avoid is the abnormal traffic of the network. Abnormal traffic is equivalent to hacker attacks. The flood-like abnormal traffic initiated by a specific port caused the network to be paralyzed and brought us huge losses. Customers could not communicate and business could not be carried out. Therefore, ensuring the stability of network traffic played a vital role

Abstract

The invention discloses a method for identifying abnormal traffic. The method comprises the following steps: capturing network traffic information through bypass packet capture, and generating traffic data according to the captured network traffic information; stabilizing the captured network traffic, modeling the time traffic in the network traffic by utilizing the principle of least square error, forecasting the feature value of the modeled traffic value, and designing a forecasting method of a user traffic behavior time sequence in the form of difference equation; and establishing a behavior model of a user according to the forecasting method of the time sequence, and judging the traffic beyond the behavior model as abnormal traffic. The method has the advantages that the abnormal traffic is judged in time by analyzing the behaviors of the user, so that the method has good instantaneity and can be applied to multiple occasions.

Description

technical field [0001] The invention relates to a method and device for identifying abnormal flow. Background technique [0002] The network is essential for us, but everything has a negative side. There will also be many obstacles when using the network, and the most difficult to avoid is the abnormal traffic of the network. Abnormal traffic is equivalent to hacker attacks. It targets certain A flood of abnormal traffic initiated by a specific port paralyzes the network and brings us huge losses. Customers cannot communicate and business cannot be carried out. Therefore, ensuring the stability of network traffic plays a vital role. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] The object of the present invention is to provide a method for identifying abnormal traffic, so as to overcome the above-mentioned shortcomings in the current prior art. [0005] The purpose of the p...
