Detect transitive access to sensitive Google Cloud resources
Blog post from P0 Security
The text discusses the issue of transitive access to sensitive Google Cloud resources, highlighting a security vulnerability in many configurations where users can indirectly access permissions through service accounts. It explains how human users might authenticate as service accounts if they have specific IAM permissions, thereby gaining access to all associated permissions. The document outlines the permissions that facilitate this transitive access and describes methods to detect it using tools like Google Policy Analyzer and Cloud Asset Inventory APIs. It also touches on best practices for managing service account keys to prevent unauthorized access. Additionally, the text introduces P0, a tool that offers a free IAM assessment to help users identify and manage access risks by showing all cloud principals and their resource access, aiming to simplify the process of securing Google Cloud resources.
