Abstract

The invention provides an anomaly detection device and method for security information interaction. The method includes the following steps of completing preprocessing operation on the basis of security information interaction records in a database to build a classifier model and conditional probability table and a group table for sequence alignment, analyzing security information interaction data, and judging the types of security information interaction related to the security information interaction data on the basis of the classifier model and conditional probability table and the group table for sequence alignment. The anomaly detection device and method for security information interaction have high security, the low false alarm rate and the low missing report rate.

Description

technical field

[0001] The present invention relates to an anomaly detection device and method, and more particularly, to an anomaly detection device and method for security information interaction. Background technique

[0002] At present, with the increasingly wide application of the network and the increasing variety of business types in different fields, the anomaly detection device and method used for security information interaction (that is, information interaction with high security requirements, such as financial transactions) become more and more complex. more and more important.

[0003] Usually, abnormal security information interaction includes the following two types: (1) does not meet the requirements of the security information interaction system on the flow and format of security information interaction; (2) meets the requirements of the security information interaction system on normal security However, the security information interaction itself has certa...
