 After you enable versioning on a bucket, it can be in either the enabled or suspended state; you cannot disable versioning on a bucket. If you suspend versioning, Amazon S3 suspends the creation of object versions for all operations but preserves any existing object versions.

Amazon S3 Security Options

Amazon S3 is API driven and is a completely abstracted service. As such, there are no security groups or Amazon VPC subnets that control access to the Amazon S3 endpoints (although individual instances can certainly block themselves from accessing Amazon S3).

Assigning the correct IAM policy document to individual users, groups, and roles is the first method for granting access to Amazon S3. You can assign permissions to individual objects or to buckets.

The advantage to using group policies is that individual buckets don’t have to be named. If new buckets are created in an account, anyone with wildcarded Amazon S3 permissions will be able to access the new bucket without edits to the policy document.

Bucket policies have the advantage of being able to grant access to other accounts without needing to create a role for them in the account that owns the bucket.
