研发背景
公司安全部目前针对内部系统的网络访问日志的安全审计,大部分都是T+1时效,每日当天,启动Python编写的定时任务,完成昨日的日志审计和检测,定时任务运行完成后,统一进行企业微信告警推送。这种方案在目前的网络环境和人员规模下,呈现两个痛点,一是面对日益频繁的网络攻击、钓鱼链接,T+1的定时任务,难以及时进行告警,因此也难以有效避免如关键信息泄露等问题,二是目前以Python为主的单机定时任务,针对不同场景的处理时效,从一小时到十几小时不等,效率低下。为解决以上问题,本人协助公司安全部同时对告警采集平台进行改造,由之前的python单机任务处理,切换到基于Flink集群的并行处理,且告警推送时效,由之前的T+1天,提升到秒级实时告警。本次改造涉及网络日志审计的多个常见场景,如端口扫描、黑名单统计、异常流量、连续恶意登录等。本次以一段时间内连续登录失败20次后,下一次登录成功场景来进行介绍。
场景描述
针对一个内部系统,如邮件系统,公司员工的访问行为日志,存放于kafka,我们希望对于一个用户账号在同一个IP下,任意的3分钟时间内,连续登录邮件系统20次失败,下一次登录成功,这种场景能够及时获取并推送到企业微信某个指定的安全接口人。kafka中的数据,能够通过某个关键字,区分当前网络访问是否一次登录事件,且有访问时间(也就是事件时间)。在解析到符合需求的用户账号之后,第一时间进行企业微信告警推送,并将其这段时间内的访问行为,写入下游ElasticSearch。
组件版本
- Flink-1.14.4
- Java8
- ElasticSearch-7.3.2
- Kafka-2.12_2.8.1
日志结构
IP和账号皆为测试使用。- {
- "user": "wangxm",
- "client_ip": "110.68.6.182",
- "source": "login",
- "loginname": "wangxm@test.com",
- "IP": "110.8.148.58",
- "timestamp": "17:58:12",
- "@timestamp": "2022-04-20T09:58:13.647Z",
- "ip": "110.7.231.25",
- "clienttype": "POP3",
- "result": "success",
- "@version": "1"
- }

技术方案
上述场景,可考虑使用FlinkCEP及Flink的滑动窗口进行实现。由于本人在采用FlinkCEP的方案进行代码编写调试后,发现并不能满足,因此改用滑动窗口进行实现。
关键代码
主入口类
主入口类,创建了flink环境、设置了基础参数,创建了kafkaSource,接入消息后,进行了映射、过滤,并设置了水位线,进行了分组,之后设置了滑动窗口,在窗口内进行了事件统计,将复合条件的事件收集返回并写入ElasticSearch。
针对map、filter、keyBy、window等算子,都单独进行了编写,后面会一一列出来。

复制代码 窗口函数(核心代码)
这里我们主要考虑使用一个事件列表,用来存储每一个窗口期内得到的连续登录,当检测到登陆失败的事件,即存入事件列表中,之后判断下一次登录失败事件,如果检测到登录成功事件,但此时登录失败的次数不足20次,则清空loginEventList,等待下一次检测。一旦符合窗口内连续登录失败超过20次且下一次登录成功这个事件,则清空此时的loginEventList并将当前登录成功的事件进行告警推送。
