A method and system for online real-time script detection

Abstract

The invention provides an online real-time script detecting method and an online real-time script detecting system. The method includes scanning a starting mark and an ending mark of a script in each data message; if the marks can be found in a data message, calling a script detecting engine to detect the script; if only the starting mark of the script is found, caching an embedded script in a current message, recombining the current message with a follow-up message in same connection until the ending mark of the script is found, restoring a complete script, and calling the script detecting engine to detect the script; setting a maximum caching length threshold in order to prevent excessive caching content, and if the caching length exceeds the threshold during recombining, stopping caching and directly sending existing caching content to the script detecting engine for detecting. By the online real-time script detecting method, caching quantity of a webpage is greatly reduced, and processing performance of equipment is improved.

Description

technical field [0001] The invention relates to a web page embedded script detection technology, in particular to an online real-time script detection method and system. Background technique [0002] With the popularization and rapid development of the Internet, the number of Internet users has increased dramatically, and network content and network applications have been greatly enriched; the actual needs of users have promoted the rapid development of web page interaction capabilities. Web development engineers often implement interactive effects by embedding scripts in web pages. [0003] Due to various reasons, the browsers used by ordinary users to surf the Internet may have loopholes of one kind or another. These vulnerabilities are often exploited by hackers. By embedding scripts in webpages, they trigger the execution of malicious codes to achieve the purpose of disseminating malicious codes and seeking illegal benefits. [0004] However, there are a large number o...
