Apache ModSecurity：另一个具有相同 ID 错误的规则

Question

我正在尝试使用 ModSecurity Rule set inside a Docker container. I followed a few tutorials (this, this and this) 设置 Apache 服务器以构建安全的 Apache 服务器。但是我无法让服务器使用规则集。

我收到这个错误：

AH00526: Syntax error on line 855 of /etc/httpd/modsecurity.d/crs-setup.conf:
ModSecurity: Found another rule with the same id

我搜索了错误，根据答案on this page，错误在于两次包含相同的规则。但据我所知，我没有两次包含相同的规则，我想知道错误是否出在其他地方。

我的项目文件结构如下：

.
├── conf
│   └── httpd.conf
├── Dockerfile
├── index.html
├── modsecurity.d
│   ├── crs-setup.conf
│   ├── modsecurity.conf
│   └── rules

httpd.conf 文件是用于 Apache 服务器的默认配置文件，modsecurity 配置通过 Dockerfile 中的命令插入。

Dockerfile有如下配置

FROM centos:7

RUN yum -y update && \
    yum -y install less which tree httpd mod_security && \
    yum clean all

COPY index.html /var/www/html/

#COPY conf/ /etc/httpd/conf/
COPY modsecurity.d/crs-setup.conf /etc/httpd/modsecurity.d/
COPY modsecurity.d/modsecurity.conf /etc/httpd/modsecurity.d/
COPY modsecurity.d/rules/* /etc/httpd/modsecurity.d/rules/

RUN echo "ServerName localhost" >> /etc/httpd/conf/httpd.conf
RUN echo "<IfModule security2_module>" >> /etc/httpd/conf/httpd.conf
RUN echo "  Include modsecurity.d/crs-setup.conf" >> /etc/httpd/conf/httpd.conf
RUN echo "  Include modsecurity.d/rules/*.conf" >> /etc/httpd/conf/httpd.conf
RUN echo "  SecRuleEngine On" >> /etc/httpd/conf/httpd.conf
RUN echo "</IfModule>" >> /etc/httpd/conf/httpd.conf

EXPOSE 80

CMD ["/usr/sbin/httpd", "-D", "FOREGROUND"]

index.html 只是一个基本的 hello 文件：

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8" lang="en">
  </head>
  <body>
    <h1>Hello there</h1>
  </body>
</html>

crs-setup.conf有以下内容（不包括所有评论）

SecRuleEngine On
SecDefaultAction "phase:1,log,auditlog,pass"
SecDefaultAction "phase:2,log,auditlog,pass"
SecCollectionTimeout 600
SecAction \
 "id:900990,\
  phase:1,\
  nolog,\
  pass,\
  t:none,\
  setvar:tx.crs_setup_version=310"

modsecurity.conf只有这两行

SecRequestBodyAccess On
SecStatusEngine On

rules 是包含 ModSecurity 规则集的目录。

如果有人想看一下整个设置，我还将项目文件放在 github 上。

我找到了错误的原因。 ModSecurity 配置文件命名错误，规则文件放置在错误的目录中。

ModSecurity 文件是 modsecurity.conf，而实际上它应该是 mod_security.conf，请注意下划线 (source). The rule files should have been placed in a folder called activated_rules(source).

在我的工作配置中，我现在有以下文件夹结构：

.
├── conf
│   └── httpd.conf
├── Dockerfile
├── index.html
└── modsecurity.d
    ├── crs-setup.conf
    ├── mod_security.conf
    └── activated_rules

Dockerfile如下

FROM centos:7

RUN yum -y update && \
    yum -y install less which tree httpd mod_security && \
    yum clean all

COPY index.html /var/www/html/

RUN echo "ServerName localhost" >> /etc/httpd/conf/httpd.conf
RUN echo "<IfModule security2_module>" >> /etc/httpd/conf/httpd.conf
RUN echo "Include modsecurity.d/crs-setup.conf" >> /etc/httpd/conf/httpd.conf
RUN echo "Include modsecurity.d/activated_rules/*.conf" >> /etc/httpd/conf/httpd.conf
RUN echo "</IfModule>" >> /etc/httpd/conf/httpd.conf


COPY modsecurity.d/crs-setup.conf     /etc/httpd/modsecurity.d/
COPY modsecurity.d/mod_security.conf  /etc/httpd/conf.d/
COPY modsecurity.d/rules/*            /etc/httpd/modsecurity.d/activated_rules/

EXPOSE 80

CMD ["/usr/sbin/httpd", "-D", "FOREGROUND"]
