Detecting privilege escalation in your AWS environment
You are an Amazon Web Services (AWS) admin who manages AWS resources and services across your organization. As part of your role, you need to be able to query your AWS CloudTrail to detect activities related to privilege escalation.
Amazon Web Services provides a feature called Identity and Access Management (IAM) which enables organizations to manage various AWS services and resources in a secure way. All IAM users have roles, groups, and policies associated with them that govern and set permissions to allow a user to access specific restrictions. However, if these IAM policies are misconfigured and have specific combinations of weak permissions, attackers can gain escalated privileges.
These searches are designed to uncover these potentially malicious events.
