GET PublicAccessBlock

Description

This operation retrieves the PublicAccessBlock configuration for an Amazon S3 bucket. In order to use this operation, you must have the s3:GetBucketPublicAccessBlock permission. For more information about Amazon S3 permissions, see Specifying Permissions in a Policy in the Amazon Simple Storage Service Developer Guide.

Important

When Amazon S3 evaluates the PublicAccessBlock configuration for a bucket or an object, it checks the PublicAccessBlock configuration for both the bucket (or the bucket that contains the object) and the bucket owner's account. If the PublicAccessBlock settings are different between the bucket and the account, Amazon S3 uses the most restrictive combination of the bucket-level and account-level settings.

For more information about when Amazon S3 considers a bucket or an object public, see The Meaning of "Public" in the Amazon Simple Storage Service Developer Guide.
