DOI:10.1189cks,which is also a problem that has
plagued this field for a long time.Aiming at unknown types of intrusion attacks,an unknown attack recognition model combining
K-Means and FP-Growth algorithms is proposed to extract the rules of unknown attacks.First,for the data of a mixture of multi-
ple unknown attacks,cluster analysis is performed with K-Means based on the similarity between samples,and the silhouette co-
efficient is introduced to evaluate the effect of clustering.After the clustering is completed,the same unknown attacks are classi-
fied into the same cluster,the feature of unknown attack is manually extracted,the feature data is preprocessed,the continuous
feature is discretized,and then the frequent item sets and association rules of the unknown attack data are mined by the FP-
Growth algorithm,and finally the rule unknown attack is obtained by analyzing it.The rules of attack are used to detect this type
of unknown attack.The results show that the accuracy rate can reach 98.74%,which is higher than that of the related algo-
rithms.
