auspex is a graph-based visualization tool designed for analyzing AWS environments to understand effective access permissions and resource relationships. The tool resolves AWS policy information to determine which actions can affect specific resources within an AWS account. It takes into account how different actions may be combined to create potential attack paths, providing security teams with visibility into privilege escalation opportunities and lateral movement possibilities. auspex consists of two main components: an ingestor that collects AWS account data, and a web interface that enables interactive exploration of the collected information. The tool presents this data in a graph format, making it easier to visualize complex relationships between AWS resources, permissions, and potential security risks. The tool requires Docker for installation and can be deployed on Linux or macOS systems. It helps security professionals understand the effective permissions landscape within their AWS infrastructure by mapping out how IAM policies, resource-based policies, and service configurations interact to create access patterns.
