Abstract
Embodiments manage access to cryptography keys for database data, within a secure key store of a local key server owned by a new (security) operating system (OS) user separate from an original default OS user. Existing principles governing distinct OS user access privileges engrained within the OS itself, are leveraged to preclude the default OS user from accessing files of the new security OS user. Embodiments thus segregate the right to read secure cryptography keys of a secure key store, from the right to administer database installation on the OS level. While the original default OS user retains access to the encrypted data, the new security OS user now owns the cryptography key necessary to decrypt that database data. Thus, the default OS user is denied enough information to unlock the database data, enhancing its security. Embodiments are particularly useful for promoting data security in cloud setups and multi-tenant databases.
