Nginx+ModSecurity(3.0.x)安装教程及配置WAF规则文件

本文主要是介绍Nginx+ModSecurity(3.0.x)安装教程及配置WAF规则文件，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

本文主要介绍ModSecurity v3.0.x在Nginx环境下的安装、WAF规则文件配置、以及防御效果的验证，因此对于Nginx仅进行简单化安装。

服务器操作系统：linux 位最小化安装

一、安装相关依赖工具

Bash

yum install -y git wget epel-release
yum install -y gcc-c++ flex bison yajl lmdb lua curl-devel curl GeoIP-devel zlib-devel pcre-devel pcre2-devel libxml2-devel ssdeep-devel libtool autoconf automake make#以下组件无法直接yum安装，需要手动下载安装，请注意检查devel包与系统中对应组件的版本一致性
wget http://rpmfind.net/linux/centos/8-stream/PowerTools/x86_64/os/Packages/lua-devel-5.3.4-12.el8.x86_64.rpm
wget http://rpmfind.net/linux/centos/8-stream/PowerTools/x86_64/os/Packages/yajl-devel-2.1.0-12.el8.x86_64.rpm
wget http://rpmfind.net/linux/centos/8-stream/PowerTools/x86_64/os/Packages/lmdb-devel-0.9.24-2.el8.x86_64.rpm
wget http://rpmfind.net/linux/centos/8-stream/PowerTools/x86_64/os/Packages/doxygen-1.8.14-12.el8.x86_64.rpm
yum localinstall -y lua-devel-5.3.4-12.el8.x86_64.rpm
yum localinstall -y yajl-devel-2.1.0-12.el8.x86_64.rpm
yum localinstall -y lmdb-devel-0.9.24-2.el8.x86_64.rpm
yum localinstall -y doxygen-1.8.14-12.el8.x86_64.rpm

二、安装Modsecurity

Bash

cd /usr/local
git clone https://github.com/SpiderLabs/ModSecurity
cd ModSecurity
git checkout -b v3/master origin/v3/master
git submodule init
git submodule update
sh build.sh
./configure
make -j4
make install

三、安装nginx与ModSecurity-nginx

Bash

cd /usr/local
git clone https://github.com/SpiderLabs/ModSecurity-nginx
wget http://nginx.org/download/nginx-1.16.1.tar.gz
tar -xvzf nginx-1.16.1.tar.gz
cd /usr/local/nginx-1.16.1
./configure --add-module=/usr/local/ModSecurity-nginx
make -j4
make install

四、测试效果

启动nginx

Bash

#关闭防火墙
systemctl stop firewalld
#启动nginx
/usr/local/nginx/sbin/nginx

模拟攻击，测试未启动ModSecurity时的访问效果，访问URL为：http://服务器IP/?param=%22%3E%3Cscript%3Ealert(1);%3C/script%3E

效果如下：

五、下载规则文件并配置：

创建用于存在配置文件的文件夹

Bash

mkdir /usr/local/nginx/conf/modsecurity
cd /usr/local
git clone https://github.com/coreruleset/coreruleset.git
cp /usr/local/ModSecurity/modsecurity.conf-recommended /usr/local/nginx/conf/modsecurity/modsecurity.conf
cp /usr/local/ModSecurity/unicode.mapping /usr/local/nginx/conf/modsecurity/unicode.mapping
cp -r /usr/local/coreruleset/rules /usr/local/nginx/conf/modsecurity/
cp /usr/local/coreruleset/crs-setup.conf.example /usr/local/nginx/conf/modsecurity/crs-setup.conf

编辑nginx.conf

在http或server节点中添加以下内容（在http节点添加表示全局配置，在server节点添加表示为指定网站配置）：

Bash

modsecurity on;
modsecurity_rules_file /usr/local/nginx/conf/modsecurity/modsecurity.conf;

编辑modsecurity.conf

SecRuleEngine DetectionOnly改为SecRuleEngine On

同时添加以下内容：

Bash

Include /usr/local/nginx/conf/modsecurity/crs-setup.conf
Include /usr/local/nginx/conf/modsecurity/rules/*.conf

六、重新加载Nginx测试效果

Bash

/usr/local/nginx/sbin/nginx -s reload
