You can use Amazon Detective Investigation to investigate IAM users and IAM roles using indicators of compromise, which can help you determine if a resource is involved in a security incident. An indicator of compromise (IOC) is an artifact observed in or on a network, system, or environment that can (with a high level of confidence) identify malicious activity or a security incident. With Detective Investigations you can maximize efficiency, focus on the security threats, and strengthen incidence response capabilities.
Detective Investigation uses machine learning models and threat intelligence to automatically analyze resources in your AWS environment to identify potential security incidents. It lets you proactively, effectively, and efficiently use automation built on top of Detective’s behavioral graph to improve security operations. Using Detective Investigation you can investigate attack tactics, impossible travel, flagged IP addresses, and finding groups. It performs initial security investigation steps and generates a report highlighting the risks identified by Detective, to help you understand security events and respond to potential incidents.
