Ensure that IAM External Access Analyzer is enabled for all regions
Mô tả
Enable IAM External Access Analyzer for all resources in each active AWS region. IAM Access Analyzer is a service that analyzes resource policies to identify resources that can be accessed from outside the account. After the analyzer is enabled, scan results are displayed in the console showing accessible resources. These results help determine whether unintended access is permitted, making it easier for administrators to monitor least privilege access. Access Analyzer analyzes only policies applied to resources within the same AWS region. IAM External Access Analyzer helps identify resources in your account or organization that are shared with external entities. This allows detection of unintended access to resources and data. It continuously monitors policies for services such as S3 buckets, IAM roles, KMS keys, Lambda functions, and SQS queues.
