A system and method for securing data by receiving encrypted data at a security appliance transmitted from a client, wherein at least a portion of the encrypted data is encrypted according to a first encryption protocol, and wherein the encrypted data is transmitted to the security appliance according to a first data transfer protocol. The encrypted data is then decrypted at the security appliance, wherein at least a portion of the decrypted data is re-encrypted according to a second encryption protocol at the security appliance. The re-encrypted data is transmitted from the security appliance to a storage device, wherein the re-encrypted data is transmitted according to a second data transfer protocol that is different than the first data transfer protocol.

Protocol translation

A data security appliance intercepts out-of-band control traffic directed to a data storage device, wherein the out-of-band control traffic includes a command to change a configuration of the data storage device. The data security appliance is reconfigured in accordance with the command in order to conform with a new configuration of the data storage device.

Encryption using copy-on-encrypt determines that plaintext data stored in a plaintext buffer is to be written out to an encrypted storage resource. In response to the determining, an encryption buffer is allocated. The plaintext data is copied from the plaintext buffer to the encryption buffer and the encryption buffer is encrypted. Encrypted data from the encryption buffer is written to the encrypted storage resource. The encryption buffer is de-allocated. Read or write requests from a client are satisfied by retrieving the plaintext data from the plaintext buffer.
