Problems solved by technology

[0003] Since the attack signatures in the attack signature database are usually obtained by parsing the data packets that have been identified as abnormal data flows, although the attack signature database has a high recognition accuracy for these identified abnormal data flows, but the The scope of abnormal data flow is small, and it is impossible to identify new abnormal data flow that has not been identified as abnormal data flow and abnormal data flow disguised as normal data flow

Abstract

The invention provides a data flow identification method and device. The method is applied to network equipment, and comprises the following steps: receiving a data packet sent by intrusion preventionequipment; finding a corresponding data packet feature table item from a preset data packet feature table according to the packet feature information of the data packet; if the abnormal level of thedata stream is lower than the specified level, inputting the data packet into a data stream identification model matched with the abnormal level of the data stream, and identifying whether the data stream to which the data packet belongs is an abnormal data stream or not according to an output result of the data stream identification model; and if the abnormal level of the data stream is higher than the specified level, identifying the data stream to which the data packet belongs as an abnormal data stream. On the basis of the intrusion prevention equipment, supplementary identification is carried out on the data stream identified as the non-abnormal data stream by the intrusion prevention equipment, so that the defect that the identification range of the intrusion prevention equipment onthe abnormal data stream is relatively small is overcome.

Description

technical field [0001] The present application relates to network security technology, in particular to a data flow identification method and device. Background technique [0002] At present, the attack signature database in the intrusion prevention device is usually used to identify abnormal data flow. After receiving the data packet, the intrusion prevention device will extract the packet feature of the data packet and match it with the attack signature in the attack signature database. If the match is successful, the data flow to which the data packet belongs will be identified as an abnormal data flow. [0003] Since the attack signatures in the attack signature database are usually obtained by parsing the data packets that have been identified as abnormal data flows, although the attack signature database has a high recognition accuracy for these identified abnormal data flows, but the The scope of the abnormal data flow is small, and it is impossible to identify the a...
