Disk Encryption

EVS enables you to encrypt data on newly created disks as required.

It uses the industry-standard XTS-AES-256 cryptographic algorithm and keys to encrypt EVS disks. Keys used to encrypt EVS disks are provided by the Key Management Service (KMS) of , which is secure and convenient. You do not need to establish and maintain the key management infrastructure. KMS uses the Hardware Security Module (HSM) that complies with FIPS 140-2 level 3 requirements to protect keys. All user keys are protected by the root key in HSM to prevent key exposure.

The encryption attribute of a disk cannot be changed after the disk is purchased.
