Set up Bucket and Object Permissions
Explore how to secure your AWS S3 buckets and objects by setting permissions effectively. Understand default privacy settings, learn to manage access with IAM, bucket policies, ACLs, and block public access options to protect your data from unauthorized use.
We'll cover the following...
After data upload, we need to ask ourselves, “Is our data secure from any unauthorized access, and if not, how do we restrict the access?”.
By default, AWS only allows the resource owner or the account owner access to resources. This means all created resources are private by default.
In case we need to provide access to the bucket to other services or users, there are multiple access management features available in S3 that allow authorized access.
AWS recommends following the principle of least privilege while granting permissions. This means we only grant permissions that are necessary to perform any specific task instead of granting full access rights.
