AWS re:Invent 2017: Amazon GuardDuty Launch

AWS launched Amazon GuardDuty, an intelligent threat detection service that continuously monitors AWS accounts and workloads for malicious activity and unauthorized behavior. This service laid crucial groundwork by providing high-fidelity security findings that Detective would later integrate.

Significance

GuardDuty's emergence highlighted the need for intelligent threat detection and generated the precise kind of security findings that would later become a primary input for Amazon Detective, underscoring the problem of correlating these findings.
