AWS IAM Access Analyzer is a service that helps you identify the resources in your organization and accounts, such as Amazon S3 buckets or IAM roles, that are shared with an external entity. This lets you identify unintended access to your resources and data, which is a security risk. IAM Access Analyzer uses logic-based reasoning to analyze the resource-based policies in your AWS environment. For each instance of a resource shared outside of your account, IAM Access Analyzer generates a finding. Findings include information about the access and the external principal granted to it345. References: 3: Using AWS Identity and Access Management Access Analyzer, 4: IAM Access Analyzer - Amazon Web Services (AWS), 5: Welcome - IAM Access Analyzer
