How can you secure data in Amazon S3?

* Bucket Policies and IAM Roles : Define who can access buckets and objects.

* Server-Side Encryption (SSE) : Encrypts data at rest using AES-256 or AWS KMS.

* Client-Side Encryption : Data is encrypted before uploading.

* Access Control Lists (ACLs) : Control access at the bucket or object level.

* Enable MFA Delete : Adds a layer of protection for delete operations.
