Ensure that IAM Access analyzer is enabled for all regions

Severity: Medium

Resource Types: AWS::AccessAnalyzer::Analyzer

Description​

Access Analyzer generates a finding when a policy on a resource within your zone of trust allows access from outside your zone of trust. Enable IAM Access analyzer for IAM policies about all resources. After the Analyzer is enabled in IAM, scan results are displayed on the console.

AWS IAM Access Analyzer 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. IAM Access Analyzer continuously monitors all policies for S3 bucket, IAM roles, KMS(Key Management Service) keys, AWS Lambda functions, and Amazon SQS(Simple Queue Service) queues.
