Question

What measures can I take to secure my AWS S3 buckets?

Answer 1

• Enforce access control using S3 bucket policies and IAM policies.
• Enable versioning to maintain a history of object changes and prevent accidental deletions.
• Implement bucket logging to track access to your S3 resources.
• Example bucket policy to restrict access to a specific IAM user:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::123456789012:user/username"
            },
            "Action": "s3:*",
            "Resource": "arn:aws:s3:::example-bucket/*"
        }
    ]
}
