以下是有关在nginx中引入ModSecurity＆OWASP Core Rule Set的笔记

1. 创建 Nginx 用户并安装软件包。

useradd -s /sbin/nologin -d /usr/local/nginx -M nginx
yum install -y gcc make automake autoconf libtool git
yum install -y pcre pcre-devel libxml2 libxml2-devel curl curl-devel httpd-devel
yum install -y openssl openssl-devel
yum install zlib zlib-devel

2. 安装modsecurity

cd /usr/local/src/
yum install git -y
git clone https://github.com/SpiderLabs/ModSecurity.git mod_security
cd mod_security/

./autogen.sh

修改configure.ac

添加 AM_PROG_CC_C_O

./autogen.sh


CFLAGS="-DDEFAULT_USER=\\\"nginx\\\" -DDEFAULT_GROUP=\\\"nginx\\\"" CPPFLAGS="-I/usr/include/apr-1 -I/usr/include/httpd" ./configure --disable-apache2-module --disable-mlogc --enable-standalone-module
make
make install

3. 安装nginx

cd /usr/local/src/
wget http://nginx.org/download/nginx-1.8.0.tar.gz
tar xzvf nginx-1.8.0.tar.gz 
cd nginx-1.8.0
./configure --user=nginx --group=nginx --add-module=../mod_security/nginx/modsecurity --with-http_ssl_module --with-http_realip_module --with-cc-opt="-I/usr/include/apr-1 -I/usr/include/httpd" --with-ld-opt="-lapr-1 -laprutil-1"
make
make install

vi /etc/init.d/nginx
chmod +x /etc/init.d/nginx 
chkconfig --add nginx
chkconfig nginx on
chkconfig --list

4. 添加CRS规则 CRS

cd  /usr/local/etc/
mkdir modsecurity
cd modsecurity
git clone https://github.com/SpiderLabs/owasp-modsecurity-crs crs

ln -s crs/base_rules/modsecurity_35_bad_robots.data .
ln -s crs/base_rules/modsecurity_40_generic_attacks.data .
ln -s crs/base_rules/modsecurity_35_scanners.data .
ln -s crs/base_rules/modsecurity_50_outbound.data .
ln -s crs/base_rules/modsecurity_50_outbound_malware.data .

cp /usr/local/src/mod_security/modsecurity.conf-recommended modsecurity.conf

5. 规则更新

cd /usr/local/etc/modsecurity/crs
git pull
cd ..

cat crs/modsecurity_crs_10_setup.conf.example crs/base_rules/*.conf > modsecurity_crs.conf

注：假陽性問題

如果直接应用这个规则，连AWS的ELB健康检查都无法通过。
首先，在modsecurity_crs.conf文件中将SecRuleEngine设置为DetectionOnly模式，
然后查看/var/log/modsec_audit.log日志文件，来进行规则调整。

nginx的启动脚本
