Amazon AWS S3 storage is widely deployed to store everything from customer data, server logs, software repositories and so on. Poorly secured S3 buckets have resulted in many publicized data breaches. The cloud service provider's shared responsibility model places responsibility on customers for protecting the confidentiality, availability and integrity of their data. Thales Cipher Trust Encryption Cloud Object Storage for S3 secures S3 objects by enabling advanced encryption along with dual end point access controls.
