我们在开发和生产环境中共使用了7个
Windows Server(2008/2012)R2标准版.上个月我们的服务器遭到破坏,我们在Windows事件查看器中发现许多失败的尝试日志.我们尝试过cyberarms IDDS,但事先证明它并不好.
现在我们重新映像了所有服务器并重命名了Administrator / guest帐户.在再次设置服务器之后,我们使用this idds来检测和阻止不需要的IP地址.
IDDS工作正常,但我们仍然在事件查看器中获得4625个事件而没有任何源IP地址.如何阻止来自匿名IP地址的这些请求？

更新：
检查我的防火墙日志后,我认为这些4625事件无论如何都与Rdp无关,但可能是SSH或任何其他我不熟悉的尝试
即使启用了NLA,也会在此处记录失败的RDP尝试的IP地址(无需调整)(在Server 2012 R2上测试,不确定其他版本)
