Data Loss is the result of unintentionally or accidentally deleting data, forgetting where it is stored, or exposure to an unauthorized party. Data loss is typically better than a data breach, where a breach is stolen information, data loss is mostly the unintentional deleting of data, but it does still include information getting into the wrong hands.
