Embodiment Construction

[0057]以下将参照附图，对本发明的优选实施例进行详细的描述。应当理解，优选实施例仅为了说明本发明，而不是为了限制本发明的保护范围。

[0058]本领域技术人员可以理解，除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同；本文中在申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请；本申请的说明书和权利要求书及上述附图说明中的术语"包括”和"具有”以及它们的任何变形，意图在于覆盖不排他的包含。本申请的说明书和权利要求书或上述附图中的术语"第一”、"第二”等是用于区别不同对象，而不是用于描述特定顺序。

[0059]在本文中提及"实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。

[0060]目前，对待与xss攻击的防御，最主要就是对用户的输入要进行安全过滤，比如对用户的输入过滤掉、alert、iframe等关键字，但黑客通过在上述关键字中间加入空格，即可轻松的避开对scriptalertiframe的过滤，例如将javascript写为javascript；对于安全过滤的策略，还可以通过白名单策略和黑名单策略，通过穷举白名单内的关键词或字符串达到过滤数据的目的。

[0061]以上方法均是通过关键词或关键语句的检测识别XSS攻击，但是，以上方法均是基于已知的字符和关键词，而随着系统的升级和新技术的不断研发，会出现新的XSS攻击策略，曾经的白名单会存在漏报的问题，曾经的黑名单会存在误报的问题，使得目前的防范XSS攻击的方式存在着误报和漏报的问题。

[0062]为解决上述问题，在本发明实施例提供的基于web应用运行时的零规则XSS攻击检测中，通过获取用户访问数据，其中，所述用户访问数据至少包括用户访问请求、验证信息和Cookie；将所述访问数据发送至镜像服务器，其中，所述镜像服务器至少包括服务器内web应用及空白信息；记录所述访问数据在镜像服务器内的行为，判断用户此次访问行为是否包含XSS攻击，其中，所述行为至少包括脚本运行、读取数据、存储数据、发送数据和篡改数据；输出判断结果。本发明实...

Abstract

The invention provides a zero-rule XSS attack detection method based on web application runtime, and the detection method comprises the steps: obtaining user access data which at least comprises a user access request, verification information and Cookie; sending the access data to a mirror image server, wherein the mirror image server at least comprises web applications in the server and blank information; recording the behavior of the access data in the mirror image server, and judging whether the access behavior of the user contains the XSS attack or not, wherein the behavior at least comprises script operation, data reading, data storage, data sending and data tampering. The detection method provided by the embodiment of the invention can effectively solve the problems of missing report and false report of the current XSS attack detection method, and improves the accuracy of XSS attack detection.

Description

technical field [0001] The invention relates to the technical field of network protection, in particular to a zero-rule XSS attack detection method based on web application runtime. Background technique [0002] A cross-site scripting (XSS) attack is an injection security attack in which an attacker injects data (such as a malicious script) into a web application on another trusted website, and the data (malicious script) will be included in the In the dynamic content of the server, the victim will download and execute the data (malicious script) when opening the browser without knowing it. At this time, the attacker can use this vulnerability to steal the user account, and can complete illegal transfers, illegal Malicious behaviors such as transferring money, hanging horses on web pages, and controlling the victim's machine for DDOS attacks, cross-site scripting (XSS) attacks have great security risks. [0003] For web applications, when a user accesses the application thr...
