We prioritize data security immensely! Over the years, we have integrated numerous security and encryption features across different AWS services. We safeguard data at rest with Server-Side Encryption for Amazon S3 and Amazon Glacier, multiple layers of encryption for Amazon Redshift, and Transparent Data Encryption for Oracle and SQL Server databases via Amazon RDS. Additionally, we ensure data in transit is protected with robust SSL/TLS support in CloudFront, Amazon RDS, and Elastic Load Balancing.
Today, we are excited to introduce another enhancement: encryption for EBS data volumes and their associated snapshots. You can now encrypt data stored on an EBS volume, both at rest and during transmission, simply by selecting a single option. When you create an encrypted EBS volume and attach it to a compatible instance type, all data on the volume, disk I/O, and the snapshots derived from it will be encrypted. This encryption takes place on the servers hosting the EC2 instances, ensuring that data remains secure as it moves between EC2 and EBS.
Enabling Encryption
You can enable EBS encryption when you create a new volume:
You can monitor the encryption status of all your volumes from the console:
Key Details
Adding encryption to a provisioned IOPS (PIOPS) volume will not influence the provisioned performance. The effect of encryption on I/O latency is minimal.
Snapshots taken from an encrypted EBS volume are also encrypted and can be transferred between AWS Regions as necessary. However, encrypted snapshots cannot be shared with other AWS accounts or made public.
As previously mentioned, your data is encrypted before it exits the EC2 instance. To maintain efficiency and low latency, the EBS encryption feature is available exclusively on EC2’s M3, C3, R3, CR1, G2, and I2 instance types. You cannot attach an encrypted EBS volume to other instance types.
Moreover, you cannot enable encryption for an existing EBS volume. Instead, you must create a new encrypted volume and transfer the data from the existing one using your preferred file manipulation tool. Rsync (Linux) and Robocopy (Windows) are excellent choices, but there are many alternatives available.
Each newly created volume receives a unique 256-bit AES key; volumes created from encrypted snapshots will share this key. You won’t need to manage the encryption keys since they are secured by our key management infrastructure, which employs stringent logical and physical security measures to prevent unauthorized access. Your data and related keys are encrypted using the industry-standard AES-256 algorithm.
Encrypt Now
EBS encryption is currently available in all eight commercial AWS Regions, so you can start utilizing it today! There are no fees for encryption, and it does not affect the published EBS Service Level Agreement (SLA) for availability.
