AWS-WAF-Log S3存放，通过Athena查看

1.创建好waf-cdn 并且设置好规则和log存储方式为s3

在这里插入图片描述

2. Amazon Athena 服务使用（注意s3桶位置相同得区域）

https://docs.aws.amazon.com/zh_cn/athena/latest/ug/waf-logs.html#waf-example-count-matched-ip-addresses
官方文档参考,建一个分区查询表

不能直接使用因为是cdn 资源需要修改相关字段

CREATE EXTERNAL TABLE `waf_logs`(`timestamp` bigint,`formatversion` int,`webaclid` string,`terminatingruleid` string,`terminatingruletype` string,`action` string,`terminatingrulematchdetails` array <struct <conditiontype: string,sensitivitylevel: string,location: string,matcheddata: array < string >>>,`httpsourcename` string,`httpsourceid` string,`rulegrouplist` array <struct <rulegroupid: string,terminatingrule: struct <ruleid: string,action: string,rulematchdetails: array <struct <conditiontype: string,sensitivitylevel: string,location: string,matcheddata: array < string >>>>,nonterminatingmatchingrules: array <struct <ruleid: string,action: string,overriddenaction: string,rulematchdetails: array <struct <conditiontype: string,sensitivitylevel: string,location: string,matcheddata: array < string >>>,challengeresponse: struct <responsecode: string,solvetimestamp: string>,captcharesponse: struct <responsecode: string,solvetimestamp: string>>>,excludedrules: string>>,

)
PARTITIONED BY (

`date` string)

修改< >中的字符为自己的资源

测试查询

SELECT COUNT(httpRequest.country) as count, httpRequest.country 
FROM waf_logs
WHERE terminatingruletype='RATE_BASED' 
GROUP BY httpRequest.country
ORDER BY count
LIMIT 100;

SELECT COUNT(*) AS count,webaclid,action,httprequest.clientip,httprequest.uri
FROM waf_logs
WHERE terminatingruleid='<id>'
GROUP BY webaclid, action, httprequest.clientip, httprequest.uri
ORDER BY count DESC
LIMIT 100;

具体的sql 字段需要修改成自己的可以先检索全表查看字段方便搜索
