Embodiment Construction

[0026] Referring to the drawings, wherein like reference numerals represent like components, the principles of the present invention are exemplified when implemented in a suitable computing environment. The following description is based on illustrated specific embodiments of the invention, which should not be construed as limiting other specific embodiments of the invention not described in detail herein.

[0027] In the following description, specific embodiments of the present invention are described with reference to steps and symbols for operations performed by one or more computers, unless otherwise stated. Accordingly, it will be understood that the steps and operations, which at times are referred to as being performed by a computer, include manipulation by a computer processing unit of electronic signals representing data in a structured form. This manipulation transforms the data or maintains it at a location in the computer's memory system that can reconfigure or ot...

Abstract

The present invention provides a network abnormal behavior detection method and device. The method comprises: obtaining the network operation behavior of a client, combining the early-stage network operation behavior related to the network operation behavior and the network operation behavior to form a network operation behavior combination; according to the network operation behavior sequence database and the network operation behavior combination, obtaining the network operation behavior sequence related to the network operation behavior; determining whether the network operation behavior is an abnormal network operation behavior sequence or not according to the current period changing condition of the execution quantity of the network operation behavior sequence and the preset period changing condition of the execution quantity of the network operation behavior sequence; if the network operation behavior sequence is the abnormal network operation behavior sequence, rejecting the execution of the network operation behavior; and if the network operation behavior sequence is a normal network operation behavior sequence, executing the network operation behavior. The detection accuracy is high, and the network abnormal behavior detection method and device can better avoid checking mistake or checking leakage.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method and device for detecting abnormal network behavior. Background technique [0002] With the development of network technology, more and more users conduct various social activities through the Internet, such as online chatting, online games, advertising releases, and investment on Internet financial platforms. Because the passwords of the network accounts used by some users for the above-mentioned network social activities may be relatively simple, network hackers will use IP (Internet Protocol Address, network protocol address) aggregation, that is, the behavior of a large number of network accounts on a certain or a certain segment of IP The password detection of the network account is performed by means of other methods, thereby affecting the security of the user's network account. Or network hackers directly use stolen network accounts for network consumption, thereby ste...
