应用放在腾讯云上，但是日志莫名其妙有一些陌生的IP，查了一下地址标注在了后面，求大牛指导是什么原因

解决方案

应用发布到网上，除了正常访问，一般还会有如下三种情况：

1. 爬虫访问
   这种情况在tomcat打印access日志时，把 user-agent 打印出来就可以看到，会有搜索引擎名字，如baidu、sogou等，而且一般搜索引擎IP都可以反查到，可以IP查询（http://www.ip138.com）反查一下

2. 安全站点扫描
   如果使用360或其他站长安全扫描工具，也会有大量IP过来访问

3. 恶意工具扫描
   与第二项类似，安全扫描会通过之前设置好的扫描点逐步扫描，也会造成大量IP访问

排查时主要关注扫描IP是否搜索引擎或安全站点扫描IP，以及扫描的目录点来综合判断，如果判断为恶意IP，可以配合防火墙规则进行屏蔽即可。
