To safeguard business-critical production data from unauthorized personnel or attackers, it is strongly recommended to implement encryption. Encryption at rest is a method to secure the data stored on Amazon Elastic Block Store (EBS) volumes, disk I/O, and snapshots by encrypting it. The keys used for encryption are managed and protected by Amazon Key Management Service (KMS), and the encryption algorithm utilized is AES-256. To meet security and compliance requirements, it is important to ensure that all Amazon EBS volumes are encrypted. With encryption enabled, sensitive, confidential, and critical data can be stored on EBS volumes. The encryption and decryption process is carried out transparently and does not require any additional action from you, your server instance, or your application.
To ensure that all Amazon EBS volumes are encrypted, you can follow these steps:
After following these steps, the EBS volume will be encrypted, and data stored on the volume will be protected. Additionally, it is recommended to enable default encryption for all new EBS volumes created in the future. This can be done by creating a new KMS key or using an existing one and then setting up the default encryption for EBS volumes using the AWS Management Console or AWS CLI.
