ModSecurity 开源项目教程

ModSecurityModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx that is developed by Trustwave's SpiderLabs. It has a robust event-based programming language which provides protection from a range of attacks against web applications and allows for HTTP traffic monitoring, logging and real-time analysis. With over 10,000 deployments world-wide, ModSecurity is the most widely deployed WAF in existence. 项目地址:https://gitcode.com/gh_mirrors/mo/ModSecurity

项目介绍

ModSecurity 是一个开源的跨平台 Web 应用防火墙(WAF)引擎,支持 Apache、IIS 和 Nginx。它具有强大的基于事件的编程语言,能够提供对一系列针对 Web 应用的攻击的保护。ModSecurity 的核心组件是 libModSecurity,它作为一个接口,接收 Web 流量并应用传统的 ModSecurity 处理。

项目快速启动

安装 ModSecurity

首先,克隆项目仓库:

git clone https://github.com/SpiderLabs/ModSecurity.git
cd ModSecurity

然后,按照官方文档进行编译和安装:

./build.sh
./configure
make
make install

配置 ModSecurity

创建一个基本的配置文件 modsecurity.conf

SecRuleEngine On
SecRequestBodyAccess On
SecAuditEngine RelevantOnly
SecAuditLog logs/audit.log

启动示例

以下是一个简单的示例代码,展示如何使用 ModSecurity 处理 HTTP 请求:

#include "modsecurity/modsecurity.h"
#include "modsecurity/transaction.h"

int main() {
    ModSecurity *modsec;
    Transaction *transaction;
    Rules *rules;

    modsec = msc_init();
    rules = msc_create_rules_set();
    msc_rules_add_file(rules, "basic_rules.conf");
    transaction = msc_new_transaction(modsec, rules);

    msc_process_connection(transaction, "127.0.0.1", 80, "127.0.0.1", 80);
    msc_process_uri(transaction, "http://www.modsecurity.org/test?key1=value1&key2=value2&key3=value3&test=args&test=test");
    msc_process_request_headers(transaction);
    msc_process_request_body(transaction);
    msc_process_response_headers(transaction);
    msc_process_response_body(transaction);

    msc_cleanup(transaction);
    msc_rules_cleanup(rules);
    msc_free(modsec);

    return 0;
}

应用案例和最佳实践

应用案例

ModSecurity 广泛应用于金融、电商、政府等行业的 Web 应用安全防护中。例如,某大型电商平台使用 ModSecurity 来防御 SQL 注入、XSS 攻击等常见 Web 攻击。

最佳实践

  1. 规则定制:根据业务需求定制安全规则,避免误报和漏报。
  2. 日志监控:定期检查和分析 ModSecurity 的审计日志,及时发现和响应安全事件。
  3. 性能优化:合理配置 ModSecurity 的性能参数,确保不影响 Web 应用的正常运行。

ModSecurity Handbook is the definitive guide to ModSecurity, a popular open source web application firewall. Written by Ivan Ristic, who designed and wrote much of ModSecurity, this book will teach you everything you need to know to monitor the activity on your web sites and protect them from attack. Situated between your web sites and the world, web application firewalls provide an additional security layer, monitoring everything that comes in and everything that goes out. They enable you to perform many advanced activities, such as real-time application security monitoring, access control, virtual patching, HTTP traffic logging, continuous passive security assessment, and web application hardening. They can be very effective in preventing application security attacks, such as cross-site scripting, SQL injection, remote file inclusion, and others. Considering that most web sites today suffer from one problem or another, ModSecurity Handbook will help anyone who has a web site to run. The topics covered include: Installation and configuration of ModSecurity Logging of complete HTTP traffic Rule writing IP address, session, and user tracking Session management hardening Whitelisting, blacklisting, and IP reputation management Advanced blocking strategies Integration with other Apache modules Working with rule sets Virtual patching Performance considerations Content injection XML inspection Writing rules in Lua Extending ModSecurity in C The book is suitable for all reader levels: it contains step-by-step installation and configuration instructions for those just starting out, as well as detailed explanations of the internals and discussion of advanced techniques for seasoned users. A comprehensive reference manual is included in the second part of the book. Digital version of ModSecurity Handbook (PDF or EPUB) can be obtained directly from the author, at feistyduck.com.
