一条示例规则如下：
## 凡诺企业网站管理系统PHP版v3.0存在SQL注入漏洞
SecRule REQUEST_FILENAME "@rx (?i:(/admin/cms_channel\.php))" "chain,rev:'1',ver:'MYWAF_CRS/1.0.7',t:none,t:urlDecodeUni,msg:'SQL injection vulnerability',tag:'MYWAF_CRS/WEB_ATTACK/SQLI',logdata:'Matched Data: %{TX.0} found within %{MATCHED_VAR_NAME}: %{MATCHED_VAR}'"
SecRule ARGS:del "@rx (?i:(select|union|and|update|insert|\(|\-\-|#|\/\*\*))" "capture,setvar:'tx.msg=%{rule.msg}',setvar:tx.anomaly_score=+%{tx.critical_anomaly_score}"
中间的每个字段都各代表什么意思，请让我慢慢给你拆解
一、通用字段
下图是我理解中的一条较长规则的示意图：
二、其他
值得拎出来另说的有：
1、TX
该变量代表临时事务集合，用于存储数据片段，创建事务异常分值等。放入此集合的变量仅在事务完成之前可用。
2、setvar
创建，删除或更新变量。变量名称不区分大小写。
3、解码规则（t:）
此操作用于指定转换管道，用于在匹配之前转换规则中使用的每个变量的值。
三、web请求过程
1、request
例如发送请求包为：
POST /abc/def/index.php?a=1&b=2&c=3 HTTP/1.1
d=index&e=p
2、response
四、其他
如何快速写出一条规则：
写比较简单的规则，就像做填空题一样，在合适的地方将空用合适的语句填起来就可以了。下面的例子中，我会将关键部位指示出来，方便更多的人参考
## 凡诺企业网站管理系统PHP版v3.0存在SQL注入漏洞
SecRule 要圈定的REQUEST方法及其范围 "@rx (?i:(对应范围的数值))" "chain,rev:'1',ver:'MYWAF_CRS/1.0.7',t:none,t:urlDecodeUni,msg:'漏洞的英文名',tag:'MYWAF_CRS/WEB_ATTACK/漏洞类型英文简写',logdata:'Matched Data: %{TX.0} found within %{MATCHED_VAR_NAME}: %{MATCHED_VAR}'"
SecRule 要看的参数 "@rx (?i:(参数对应值))" "capture,setvar:'tx.msg=%{rule.msg}',setvar:tx.anomaly_score=+%{tx.critical_anomaly_score}"
