modsecurity原本是Apache上的一款开源waf,可以有效的增强web安全性,目前已经支持nginx和IIS,配合nginx的灵活和高效,可以打造成生产级的WAF,是保护和审核web安全的利器。
一、安装ModSecurity
yum -y install httpd-devel pcre pcre-devel libxml2-devel libxml2 cd /home/tools wget https://www.modsecurity.org/tarball/2.9.1/modsecurity-2.9.1.tar.gz tar zxvf modsecurity-2.9.1.tar.gz cd modsecurity-2.9.1 ./autogen.sh ./configure --enable-standalone-module --disable-mlogc make
二、编译nginx并添加modsecurity和nginx-sticky模块
cd /home/tools unzip nginx-sticky-module-ng.zip 解压后从命名为:nginx-goodies-nginx-sticky groupadd nginx useradd -r -g nginx -s /sbin/nologin -M nginx cd /home/tools tar zxvf nginx-1.10.3.tar.gz cd nginx-1.10.3/ ./configure \ --with-pcre \ --prefix=/usr/local/nginx \ --user=nginx \ --group=nginx \ --with-http_ssl_module \ --with-http_flv_module \ --with-http_stub_status_module \ --with-http_gzip_static_module \ --with-http_realip_module \ --add-module=/home/tools/modsecurity-2.9.1/nginx/modsecurity \ --add-module=/home/tools/nginx-goodies-nginx-sticky make && make install
三、下载OWASP规则
cd /home/tools/ git clone https://github.com/SpiderLabs/owasp-modsecurity-crs mv owasp-modsecurity-crs /usr/local/nginx/conf #移动到nginx配置目录下 cd /usr/local/nginx/conf/owasp-modsecurity-crs cp crs-setup.conf.example crs-setup.conf #拷贝模板配置文件 cd /home/tools/modsecurity-2.9.1/ cp modsecurity.conf-recommended /usr/local/nginx/conf #拷贝配置文件 cp unicode.mapping /usr/local/nginx/conf #拷贝配置文件 mv /usr/local/nginx/conf/modsecurity.conf-recommended /usr/local/nginx/conf/modsecurity.conf #重命名 vim /usr/local/nginx/conf/modsecurity.conf #修改添加 SecRuleEngine DetectionOnly #修改为SecRuleEngine On 在最后加上如下: #Include owasp-modsecurity-crs/rules/REQUEST-901-INITIALIZATION.conf #Include owasp-modsecurity-crs/rules/REQUEST-903.9001-DRUPAL-EXCLUSION-RULES.conf #Include owasp-modsecurity-crs/rules/REQUEST-903.9002-WORDPRESS-EXCLUSION-RULES.conf #Include owasp-modsecurity-crs/rules/REQUEST-905-COMMON-EXCEPTIONS.conf #Include owasp-modsecurity-crs/rules/REQUEST-910-IP-REPUTATION.conf #Include owasp-modsecurity-crs/rules/REQUEST-911-METHOD-ENFORCEMENT.conf #Include owasp-modsecurity-crs/rules/REQUEST-912-DOS-PROTECTION.conf #Include owasp-modsecurity-crs/rules/REQUEST-913-SCANNER-DETECTION.conf #Include owasp-modsecurity-crs/rules/RESPONSE-953-DATA-LEAKAGES-PHP.conf #Include owasp-modsecurity-crs/rules/REQUEST-941-APPLICATION-ATTACK-XSS.conf #Include owasp-modsecurity-crs/rules/REQUEST-942-APPLICATION-ATTACK-SQLI.conf #Include owasp-modsecurity-crs/rules/REQUEST-920-PROTOCOL-ENFORCEMENT.conf Include owasp-modsecurity-crs/rules/REQUEST-921-PROTOCOL-ATTACK.conf Include owasp-modsecurity-crs/rules/REQUEST-930-APPLICATION-ATTACK-LFI.conf Include owasp-modsecurity-crs/rules/REQUEST-931-APPLICATION-ATTACK-RFI.conf Include owasp-modsecurity-crs/rules/REQUEST-932-APPLICATION-ATTACK-RCE.conf Include owasp-modsecurity-crs/rules/REQUEST-933-APPLICATION-ATTACK-PHP.conf Include owasp-modsecurity-crs/rules/REQUEST-943-APPLICATION-ATTACK-SESSION-FIXATION.conf Include owasp-modsecurity-crs/rules/REQUEST-949-BLOCKING-EVALUATION.conf Include owasp-modsecurity-crs/rules/RESPONSE-950-DATA-LEAKAGES.conf Include owasp-modsecurity-crs/rules/RESPONSE-951-DATA-LEAKAGES-SQL.conf Include owasp-modsecurity-crs/rules/RESPONSE-952-DATA-LEAKAGES-JAVA.conf Include owasp-modsecurity-crs/rules/RESPONSE-954-DATA-LEAKAGES-IIS.conf Include owasp-modsecurity-crs/rules/RESPONSE-959-BLOCKING-EVALUATION.conf Include owasp-modsecurity-crs/rules/RESPONSE-980-CORRELATION.conf :wq! #保存退出
四、配置nginx支持Modsecurity
在需要启用modsecurity的主机的location下面加入下面两行即可:
ModSecurityEnabled on;
ModSecurityConfig modsecurity.conf;
location / {
root html;
index index.html index.htm;i
ModSecurityEnabled on;
ModSecurityConfig modsecurity.conf;
}
至此,Modsecurity模块+nginx的安装完成。
五、查看ip地址的连接数前十:
netstat -nt | awk '{print $5}' | awk -F: '{print ($1>$4?$1:$4)}' | \
sort | uniq -c | sort -nr | head 10
