Question

我用ModSecurity和owasp-modsecurity-crs构建了Nginx 1.10.3，并用curl测试它。从nginx日志开始，它可以运行，因为它已经被规则检测到，但客户端仍然获得http响应成功，而不是像403这样的预期拒绝响应。

你可以帮忙吗？是否需要任何附加配置？

[sib@sib ~]$ curl -H "User-Agent: Nikto" http://15.116.78.110
...
Welcome to nginx!

nginx error.log：

我找到了以下解决方案：

INSTALL文件说您需要为Nginx显式加载规则文件，因为Nginx本身不使用字母加载顺序。您使用了Apache Include表单* .conf，导致Nginx在您的规则触发之前评估异常分数。（ - ＆gt; 949文件在942文件之前加载。）

按如下方式加载它们，你应该没问题：

include owasp-modsecurity-crs/crs-setup.conf
include owasp-modsecurity-crs/rules/REQUEST-900-EXCLUSION-RULES-BEFORE-CRS.conf
...
include owasp-modsecurity-crs/rules/RESPONSE-999-EXCLUSION-RULES-AFTER-CRS.conf

owasp-modsecurity-crs检测到但未拒绝请求
