Nginx+ModSecurity安全模块部署的实现

目录一、下载

二、部署

1.Nginx部署

2.ModSecurity部署

3.添加ModSecurity模块

4.配置Nginx虚拟主机

为演示已安装Nginx而未添加ModSecurity的情况，以下操作为先安装Nginx，后添加ModSecurity模块。

ModSecurity是一个开源的跨平台Web应用程序防火墙（WAF）引擎，，完美兼容nginx，是nginx官方推荐的WAF，并且支持支持OWASP规则。

中文网站：http://www.modsecurity.cn

应用实战可参考：http://www.modsecurity.cn/practice/

一、下载

1.Nginx下载

wget http://nginx.org/download/nginx-1.14.2.tar.gz

2.ModSecurity下载

wget http://www.modsecurity.cn/download/modsecurity/modsecurity-v3.0.4.tar.gz

二、部署

1.Nginx部署

1.1安装依赖

yum install -y pcre* openssl* gcc c++ make

1.2 编译安装

解压文件

tar -xvf nginx-1.14.2.tar.gz cd nginx-1.14.2/

配置模块

./configure –prefix=/usr/local/nginx –sbin-path=/usr/local/nginx/sbin/nginx –conf-path=/usr/local/nginx/conf/nginx.conf –error-log-path=/var/log/nginx/error.log –http-log-path=/var/log/nginx/access.log –pid-path=/var/run/nginx/nginx.pid –lock-path=/var/lock/nginx.lock –user=nginx –group=nginx –with-http_ssl_module –with-http_stub_status_module –with-http_gzip_static_module –http-client-body-temp-path=/var/tmp/nginx/client/ –http-proxy-temp-path=/var/tmp/nginx/proxy/ –http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ –http-uwsgi-temp-path=/var/tmp/nginx/uwsgi –http-scgi-temp-path=/var/tmp/nginx/scgi –with-pcre

执行编译

make make install

创建账号和目录

useradd nginx -s /sbin/nologin mkdir /var/tmp/nginx/

2.ModSecurity部署

2.1 安装依赖

yum install -y gcc-c++ flex bison yajl yajl-devel curl-devel curl GeoIP-devel doxygen zlib-devel pcre-devel lmdb-devel libxml2-devel ssdeep-devel lua-devel libtool autoconf automake

2.2 编译安装

解压文件

tar -xvf modsecurity-v3.0.4.tar.gz cd modsecurity-v3.0.4/

编译安装

./configure make make install cp modsecurity.conf-recommended /usr/local/modsecurity/modsecurity.conf cp unicode.mapping /usr/local/modsecurity/

3.添加ModSecurity模块

3.1查看Nginx编译参数

/usr/local/nginx/sbin/nginx -V

3.2下载ModSecurity模块

git clone https://github.com/SpiderLabs/ModSecurity-nginx.git 或至下载 https://github.com/SpiderLabs/ModSecurity-nginx

3.3重新编译Nginx

解压模块

unzip ModSecurity-nginx-master.zip #仅在下载安装包情况下，如果是git clone 则不需要

编译安装

./configure –prefix=/usr/local/nginx –sbin-path=/usr/local/nginx/sbin/nginx –conf-path=/usr/local/nginx/conf/nginx.conf –error-log-path=/var/log/nginx/error.log –http-log-path=/var/log/nginx/access.log –pid-path=/var/run/nginx/nginx.pid –lock-path=/var/lock/nginx.lock –user=nginx –group=nginx –with-http_ssl_module –with-http_stub_status_module –with-http_gzip_static_module –http-client-body-temp-path=/var/tmp/nginx/client/ –http-proxy-temp-path=/var/tmp/nginx/proxy/ –http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ –http-uwsgi-temp-path=/var/tmp/nginx/uwsgi –http-scgi-temp-path=/var/tmp/nginx/scgi –with-pcre –add-module=../ModSecurity-nginx #此处需要注意/ModSecurity-nginx路径 make make install /usr/local/nginx/sbin/nginx -V #查看已经有了ModSecurity模块

添加配置文件

mkdir /usr/local/nginx/conf/modsecurity cp /usr/local/modsecurity/modsecurity.conf /usr/local/nginx/conf/modsecurity/ cp /usr/local/modsecurity/unicode.mapping /usr/local/nginx/conf/modsecurity/

4.配置Nginx虚拟主机

4.1虚拟主机配置

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

4.2Modsecurity配置

vim /usr/local/nginx/conf/modsecurity/modsecurity.conf #更改一下部分 SecRuleEngine On SecAuditLogParts ABCDEFHZ #追加到配置文件 Include /usr/local/nginx/conf/modsecurity/crs-setup.conf Include /usr/local/nginx/conf/modsecurity/rules/*.conf

4.3下载规则文件

wget http://www.modsecurity.cn/download/corerule/owasp-modsecurity-crs-3.3-dev.zip #Modsecurity中文网下载 wget https://github.com/coreruleset/coreruleset #github下载

4.4 配置规则

unzip owasp-modsecurity-crs-3.3-dev.zip cd owasp-modsecurity-crs-3.3-dev/ cp crs-setup.conf.example /usr/local/nginx/conf/modsecurity/crs-setup.conf cp -r rules /usr/local/nginx/conf/modsecurity/ cd /usr/local/nginx/conf/modsecurity/rules mv REQUEST-900-EXCLUSION-RULES-BEFORE-CRS.conf.example REQUEST-900-EXCLUSION-RULES-BEFORE-CRS.conf mv RESPONSE-999-EXCLUSION-RULES-AFTER-CRS.conf.example RESPONSE-999-EXCLUSION-RULES-AFTER-CRS.conf

4.5测试

#浏览器 或 curl访问测试，返回403 curl -I http://localhost/?id=1 AND 1=1
