Embodiment Construction

[0016] In website development, the development model of MVC is generally followed, and the front end is responsible for the display of data. The displayed pages can be divided into static resources and dynamic resources. During deployment, static resources and dynamic resources are deployed separately. A normal complete request model includes both access to static resources and access to dynamic resources. Dynamic resources are the content that crawlers are interested in. Based on this, the following embodiments determine those that do not conform to the normal request model as malicious requests (crawlers).

[0017] Therefore, the embodiment provides an anti-crawler method based on access behavior, such as figure 1 shown, including steps:

[0018] A. In the website design stage, use the MVC model to separate and deploy static resources and dynamic resources;

[0019] B. Through manual analysis and / or log analysis and / or traffic analysis, obtain the ratio T of the number o...

Abstract

The invention relates to the field of information security, and discloses an anti-crawler method based on access behaviors in order to solve the problem that it is difficult for the existing anti-crawler method to distinguish malicious requests. The method includes the following steps: in the stage of website design, static resources and dynamic resources are separately deployed in an MVC mode; the quantity ratio T of static resources to dynamic resources of a normal request within a specified time is obtained through analysis; when a website receives an access request from a client, the website analyzes whether the number of resources to be accessed within the specified time for the access request is in accordance with the quantity ratio T; if the number of resources to be accessed withinthe specified time for the access request is not in accordance with the quantity ratio T, the access request is regarded as a malicious request, and the request of the client is banned for a period of time; and if the number of resources to be accessed within the specified time for the access request is in accordance with the quantity ratio T, the access request is regarded as a normal request and is handled the same way a normal request is handled. The anti-crawler method of the invention is suitable for website development.

Description

technical field [0001] The invention relates to the field of information security, in particular to an anti-crawler method based on access behavior. Background technique [0002] With the development of the Internet today, every website has some public data for normal users to browse, but they do not want to be obtained by malicious crawlers. For example, the prices of commodities in e-commerce data are for normal users to browse, and they do not want to be easily obtained by competitors . [0003] A web crawler (also known as a web spider, a web robot, and more often referred to as a web chaser in the FOAF community) is a program or script that automatically grabs information on the World Wide Web according to certain rules. [0004] In the field of anti-crawlers, the following methods are often used: Method 1, through statistics on the IP address of the requester, when the access frequency or number of visits reaches a certain threshold, the request of this IP is blocked....
