Database encryption tools are used to protect data within relational database management systems (RDBMSs). Encryption can be implemented using native DBMS tools, third-party software tools and network-based appliances, or implemented within storage networks via fabric-based encryption. Database encryption is increasingly being implemented as a regulatory check box by clients that enable built-in encryption. There are two operational scenarios: encrypting the entire database or encrypting specific columns or fields within the RDBMS.
