Access Control List
With the help of a detailed authorization system, based on the S3 Access Control List (ACL), you can control precisely who accesses and edits your content. By assigning ACLs to a group of users as per S3-compliant ACL, you can manage who may access the buckets and objects of your IONOS S3 Object Storage.
ACL Alternatives
Use Bucket Policy instead of ACLs if you need to:
Manage access to prefixes like
/folder/*or*.jpg.Use conditions to grant access, for example, IP address.
Allow or deny certain actions like listing the object list.
Use Share Objects with Pre-Signed URLs instead of ACL for granting temporary access to authorized users for a specified period, after which the URL expires.
Manage ACLs
You can use ACLs to make a bucket or object public or to share access with certain authorized users by setting the right permissions. IONOS S3 Object Storage offers the following ACL management methods:

Block Public Access
If you have defined ACLs granting public access, activating the Block Public Access revokes these permissions, ensuring your data remains private. This feature is invaluable in scenarios where ensuring data privacy is paramount, or when you want to enforce a blanket no-public-access rule, irrespective of ACL settings.
