也是這次 AWS re:Invent 發表的服務，透過 Machine Learning 分析可能的安全問題：「Introducing Amazon Detective」。
透過現有的各種 log 建立模型分析：
Amazon Detective can analyze trillions of events from multiple data sources such as Virtual Private Cloud (VPC) Flow Logs, AWS CloudTrail, and Amazon GuardDuty, and automatically creates a unified, interactive view of your resources, users, and the interactions between them over time.
依照 log 的量算錢的，然後 preview 階段不收費，所以有興趣的人可以開起來跑看看？
