摘 要

随着网络技术的迅速发展，Web应用的广泛使用带来了一系列安全问题，其中Web入侵行为尤为突出。本文旨在设计并实现一款Web入侵防御系统，该系统通过集成SQL注入防御、跨站脚本（XSS）防御、文件包含防御以及会话劫持防御等多个功能模块，利用先进的算法和技术对Web流量进行综合检测，以确保Web应用的安全性。系统采用Python语言开发，结合scopy、SQL、CSRF等攻击手段，实现对网站漏洞的自动化检测和数据库端口的安全评估。通过输入目标网址和端口，系统能够一键式地对不同网站进行漏洞扫描，有效提升软件安全度和漏洞检测能力。此外，本文还探讨了基于B/S架构的渗透检测工具的搭建，该工具能够对Web页面漏洞和端口进行在线扫描，为网站的后期升级和保护提供有力支持。通过自动化的检测流程，系统能够及时发现并弥补安全漏洞，增强Web应用的防御能力。

Abstract

With the rapid advancement of network technology, the widespread use of Web applications has led to a series of security issues, among which Web intrusion activities are particularly prominent. This paper aims to design and implement a Web intrusion defense system that integrates multiple functional modules such as SQL injection defense, Cross-Site Scripting (XSS) defense, file inclusion defense, and session hijacking defense. The system utilizes advanced algorithms and technologies to conduct comprehensive traffic detection, ensuring the security of Web applications. Developed using the Python language, the system combines attack methods such as scopy, SQL, and CSRF to achieve automated vulnerability detection and security assessment of database ports. By entering the target website address and port, the system can perform a one-click vulnerability scan on different websites, effectively enhancing the software's security level and vulnerability detection capabilities. Furthermore, this paper also discusses the construction of a penetration testing tool based on the B/S architecture, which can perform online scanning for Web page vulnerabilities and port security. This tool provides strong support for the later upgrades and protection of websites. Through an automated detection process, the system can promptly identify and remedy security vulnerabilities, strengthening the defensive capabilities of Web applications.
