Abstract

The embodiment of the invention provides a network attack prediction method and device, and relates to the technical field of network security. The network attack prediction method comprises the following steps: firstly, obtaining to-be-detected network attack behavior data; preprocessing the network attack behavior data to obtain preprocessed data; constructing an attack event sequence according to the preprocessed data; further performing prediction processing on the attack event sequence through a pre-constructed network attack prediction model to obtain a prediction result; and finally, determining an attacked target address and an attacked probability corresponding to the attacked target address according to the prediction result. Therefore, network attack behaviors can be predicted, the prediction accuracy is high, and the network security can be further maintained in time.

Description

technical field [0001] The present application relates to the technical field of network security, in particular, to a network attack prediction method and device. Background technique [0002] The current network attacks are becoming more and more frequent, and the forms of network attacks and the application of new tools are emerging in an endless stream. In particular, attacks on key network information infrastructure often cause serious losses and even endanger network security. In the prior art, a regular expression matching a log format is usually set by a regular matching algorithm to identify whether a network attack is underway. However, it is found in practice that the existing technology can only identify network attack behaviors, but cannot predict network attack behaviors, which is not conducive to timely maintenance of network security. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a network attac...
