Page "Database" Paragraph 124

The definition of data security varies and may overlap with other database security aspects.

Broadly it deals with protecting specific chunks of data, both physically ( i. e., from corruption, or destruction, or removal ; e. g., see Physical security ), or the interpretation of them, or parts of them to meaningful information ( e. g., by looking at the strings of bits that they comprise, concluding specific valid credit-card numbers ; e. g., see Data encryption ).
