Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0039] The scripting language can provide flexible and powerful customization functions for network devices, which can be network security devices, traffic control devices, and application delivery platform devices. For example, for application delivery platform equipment, it supports most of the standard functions of application delivery, and can meet the functions and deployment requirements of most network systems in this regard. When some application systems have more detailed customization requirements for data control, or for The functional support of the standard protocol has higher requirements...

Abstract

The invention discloses a message processing method and device based on a script language. The method and the device are applied to a network device connected with a website server and a user host separately. The method comprises: sending a request message sent by the user host to the website server; receiving a response message sent by the website server, and obtaining a result set of the response message according to a preset script keyword; and determining whether the result set is empty. If the result set is not empty, the content of the response message is modified, and the modified response message which does not contain the script keyword is sent to the user host. The method and the device are applied to a network device. By setting the script keyword, the content of the response message of the website server with the script keyword is filtered, so that dangerous scripts in a webpage is filtered, a safe webpage is provided for a user, and effective protection is provided for the user during webpage browsing online.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a message processing method and device based on script language. Background technique [0002] With the rapid development of Internet technology, many users' key services are implemented based on WEB applications, such as web browsing, online shopping, and online money transfer. However, the current network security situation is relatively severe, and various attack methods emerge in an endless stream, such as: SQL (Structured Query Language, Structured Query Language) injection, website sensitive file scanning, server vulnerabilities, website program 0day and other methods to obtain the website administrator password, and then Log in to the background of the website, obtain a webshell (script attack tool for WEB intrusion) through the database upload vulnerability, use the webshell to modify the content of the website page, and add malicious redirection code to the page. ...
