Amazon S3 Security
Cloud security at AWS is the highest priority. As an AWS customer, you benefit from a data center and network architecture that are built to meet the requirements of the most security-sensitive organizations.
Security is a shared responsibility between AWS and you. The shared responsibility model describes this as security of the cloud and security in the cloud:
-
Security of the cloud – AWS is responsible for protecting the infrastructure that runs AWS services in the AWS Cloud. AWS also provides you with services that you can use securely. The effectiveness of our security is regularly tested and verified by third-party auditors as part of the AWS compliance programs. To learn about the compliance programs that apply to Amazon S3, see AWS Services in Scope by Compliance Program.
-
Security in the cloud – Your responsibility is determined by the AWS service that you use. You are also responsible for other factors including the sensitivity of your data, your organization’s requirements, and applicable laws and regulations.
This documentation will help you understand how to apply the shared responsibility model when using Amazon S3. The following topics show you how to configure Amazon S3 to meet your security and compliance objectives. You'll also learn how to use other AWS services that can help you monitor and secure your Amazon S3 resources.
