Security
-
Principal Restrictions
| — | The existing access control model has been extended to prevent direct access to data source assets. |
| — | Privilege management has been streamlined - Column-level privileges are implicitly maintained only once they have been explicitly set by the user |
| — | Controls in Studio have been simplified to allow for the scope of resources onto which the changes should be applied and the scope of privilege changes to be applied to be selected independently |
| — | READ privileges are automatically assigned on parent and ancestor containers when it is detected that any of SELECT, INSERT, UPDATE, DELETE or EXECUTE privileges are assigned on a given resource - The same implicit assignments are applied when privilege assignment is propagated on dependencies and/or dependents |
-
PAM Module improvements
| — | Login requests routed through the PAM module will now be applied only to the users who belong to the specific domain that has been configured to use the module. |
| — | The PAM login module will now also fetch the client IP address (in addition to the account credentials) to validate the clients attempting to access TDV. |
