You can manage the access to the S3 bucket at a much granular level through its permission settings. You can access its settings by navigating to the S3 bucket and clicking on the "Permissions" tab.

Here you have the option to modify:

  • "Block public access" related policies
  • Access Control Lists - modifying and creating them
  • Bucket policies
  • CORS configurations - i.e. Cross-Origin Resource Sharing for HTTP access

The "Block public access" policies are those that you set up while creating the S3 bucket. You can modify these settings here by clicking on the Edit button and can set this up at a granular level.

  1. Bucket Owner
