Embodiment Construction

[0052] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0053] The network abnormal data detection method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the server communicates with the client through the network. The client initiates a network access request to the server, the server receives the access request data sent by the client, and the server searches for the corresponding user's historical access request data according to the user session identifier in the received access request data. The server performs word segmentation processing on the header strin...

Abstract

The application relates to a network abnormal data detection method and system, computer equipment and a storage medium. The method comprises the following steps: receiving access request data sent bya client; searching for historical access request data corresponding to a user session identifier in the access request data; acquiring a header string of the access request data; performing word segmentation processing on the header string according to a preset step length to obtain a participle set; acquiring a participle weight matrix according to the historical access request data and the participle set; inputting the participle weight matrix into an abnormal data detection model to obtain data abnormal probability; and judging whether abnormal data exist in the header string or not according to the data abnormal probability. Through adoption of the method, the problems of missing and false reporting of network attacks in a website attack detection process can be avoided.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for detecting abnormal network data. Background technique [0002] While the rapid development of the Internet has brought great convenience to people's lives, it has also brought new network security challenges. Websites will inevitably suffer malicious intrusions or attacks, and people's property and information security will be threatened. Today's network Safety issues have attracted people's attention. Most of the current website attack threat analysis and detection methods and systems are based on network log analysis, and the log data is converted into structured data for storage, and character matching is performed based on specific rules. However, the above-mentioned detection methods have low processing efficiency, and it is easy for attackers to find matching rules, resulting in missed and false positives of net...
