How to create private AWS S3 bucket

Amazon S3 is a service that allows you to store a wide range of files in the cloud. These files can include public assets like JavaScript and CSS files, as well as sensitive data like logs and backups. By default, any bucket you create in S3 is set to private. This ensures that your files are not accessible to the public.

To keep your data secure, it’s essential to configure your S3 bucket settings correctly. You can create a private S3 bucket through the AWS console. Ensure that all public access is blocked during the setup process to maintain the security of your files.

Managing your bucket settings through the S3 dashboard is straightforward. Choose a unique name, select the appropriate region, and verify that the bucket remains private by default. These steps will help you securely store your files in AWS.
