amazon web services – Do you know any open source or native tools for UEBA AWS Security?

AWS provides a list of great native security tools and there is also a comprehensive list of open source cloud security tools here.

So far I haven’t been able to spot any non-third party commercial tools for User Behavior Analytics i.e threat detection based on machine learning. A tool in other words that deploys and trains a machine learning model in order to detect anomaly in the users behavior.

Are you aware of any such tools?
