Information
Without the association of security labels to information, there is no basis for the database management system (DBMS) to make security-related access-control decisions.
Security labels are abstractions representing the basic properties or characteristics of an entity (e.g., subjects and objects) with respect to safeguarding information.
These labels are typically associated with internal data structures (e.g., tables, rows) within the database and are used to enable the implementation of access control and flow control policies, reflect special dissemination, handling, or distribution instructions, or support other aspects of the information security policy.
One example includes marking data as classified or CUI. These security labels may be assigned manually or during data processing, but, either way, it is imperative these assignments are maintained while the data is in storage. If the security labels are lost when the data is stored, there is the risk of a data compromise.
Some DBMS systems provide the feature to assign security labels to data elements. If labeling is required, implementation options include the Oracle Label Security package, or a third-party product, or custom-developed functionality. The confidentiality and integrity of the data depends upon the security label assignment where this feature is in use.

Solution
Define the policy for security labels defined for the data.
Document the security label requirements and configure database security labels in accordance with the policy.
To provide reliable security labeling of information in storage, enable DBMS features; deploy third-party software; or add custom data structures, data elements and application code.
