Oracle Label Security

Oracle Label Security

Oracle Label Security (OLS) is a feature in Oracle Database that provides multilevel security capabilities for sensitive data. OLS allows you to define and enforce security policies that restrict access to data based on the security level assigned to the data and the security clearance of the user.

Here is an example of using OLS to create a security policy:

BEGIN

   DBMS_MACADM.CREATE_SECURITY_POLICY(

      policy_name => 'my_policy',

      description => 'Security policy for sensitive data',

      security_model => 'MULTILEVEL',

      label_function => 'my_label_function',

      label_column => 'security_label',

      enabled => TRUE

   );

   DBMS_MACADM.ADD_AUTH_TO_POLICY(

      policy_name => 'my_policy',

      auth_name => 'my_auth',

      auth_option => DBMS_MACUTL.GRANT,

      auth_grantee => 'my_user'

   );

END;
