Security of Amazon S3 is a shared responsibility. Cloud security at AWS is the highest priority. AWS is responsible for the "security of the cloud," whereas customers are responsible for "security in the cloud". 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. This eBook addresses foundational Amazon S3 security best practices and guidelines for you to consider as you develop and implement your own storage security policies. The best practices and guidelines don't represent a complete security solution, treat them as helpful considerations rather than prescriptions.
