Embodiment Construction

[0035] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0036] Referring to shown in Figure 1, the detection system of illegal access in the embodiment of the present invention mainly includes:

[0037] The flow information collection module 101 is configured to sample local traffic, and send the collected data packets to the flow information aggregation module.

[0038] The flow information aggregation module 102 is configured to summarize and filter the data packets acquired by each flow information collection module, extract useful flow information in the data packets, and combine the same flow information.

[0039] In a preferred embodiment of the present invention, the flow information collecting module 101 and the flow information converging module 102 can be realized by software modules by utilizing the NetFlow function provided by the network eq...

Abstract

The invention discloses a system for detecting illegal access and a method thereof. The system comprises a flow information acquisition module for sampling local flow data and sending the acquired data packet to a stream information convergence module; a flow information convergence module for extracting flow data from the data packet acquired from the stream information acquisition module and merging the same flow information; a information management module for storing and maintaining the information of legal user; and a decision analysis module for judging and filtering the information belonging to the user of operator from the flow information converged from the flow information convergence module. The rest information after filtering is compared with the information of legal user in the information management module, if yes, the user is judged as normal flow user, and if not, the user is judged as illegal access user. The invention can automatically find illegal access user.

Description

technical field [0001] The invention relates to flow monitoring and flow control technology in the field of network management, in particular to a detection system and method for illegal access. Background technique [0002] The connection methods between different networks can be divided into two categories, namely, access and interconnection. Access refers to the customer's connection to the network of the network service provider in a certain way; interconnection refers to the intercommunication connection between the networks of the network service provider. The difference between these two methods is not in technology, but in the logical relationship between networks, especially in the settlement method of traffic charges between networks. [0003] With the popularization of the Internet, more and more enterprises and individuals will use the Internet business. Driven by commercial interests, in some areas, when some operators (Party B) connect to other operators (Par...
