Making some object of the same bucket private and some public?

I am just a beginner to AWS. I was learning about S3 and making bucket public by editing the public access setting of a bucket.

So, I wanted to ask that can I make some objects of the same bucket private and some public?

By default, all objects in an Amazon S3 bucket are private.

There are severals ways to grant access to objects:

  • Use a Bucket Policy to make a bucket, or part of a bucket, public. This is useful for static websites where anyone can access content.
  • Use an IAM Policy on an IAM User or IAM Group to grant access to a bucket (or part of a bucket) to a specific user or group of users. This is ideal for job-specific access.
  • Use an Access Control List (ACL) on an object to make a specific object public. This requires the permission to be set on each specific object, so is safer than making a whole bucket public.
  • Use a Pre-Signed URL when your application programmatically determines whether somebody should gain access to an object. For example, if your application is a photo-sharing website, the app can determine which user is entitled to see which photos. It can then generated a time-limited URL that grants temporary access to the object. Ones the URL expires, access is no longer available.

So, to answer your question:

  • There is no need to "make some objects of the same bucket private" because they are private by default
  • Choose one of the above methods to grant public access, or access to specific users
