Field Level Security

Field Level Security (FLS) is a feature in SuperSTAR that allows administrators to control access to data. Access to fields and/or field values can be limited for specific users or user groups.

Note

  • You cannot use field level security to hide field groups.
  • Field level security settings do not apply to users who are SuperADMIN administrators. Do not attempt to configure any field level security for these users.
  • Do not apply field level security to the default summation option. This must always be available to all users.
  • If you have weighted databases, do not apply field level security to the main weight.
  • Before you start configuring permissions, make sure you understand the Permissions Model - Inheritance and Conflicts.

Example

This example uses the standard Retail Banking database, which contains data for Australian States accessible via a geographic hierarchy.

In the example scenario a certain user (vicuser1) must only be able to access data for the state of Victoria; other users can see data for all states.

The following examples show the effect of implementing Field Level Security.

SuperCROSS

For vicuser1, only Victoria is available in the Area field:

For other users, all states are available:

SuperWEB2

What can be Hidden using Field Level Security?

Field level security lets you hide the following elements in a SuperSTAR database:

ElementDescription
Cross-Tabulation FieldA complete field. SuperADMIN refers to this as an XTAB Field.
Value SetField at levels lower than the top level in the hierarchy.
Field ValuesThe individual values within a field or value set.
Summation Field

A continuous variable/measure available in the clients through the Summation Options.

Do not use field level security on the default summation option, or on the main weight if this is a weighted database.

This applies even if you are using the SuperWEB2 rules engine to override the default summation option. The default summation configured in the SXV4 must be accessible to all users.

Example: Field

This example shows the effect of implementing Field Level Security to hide a cross-tabulation field.

User with full access: Marital Status field is available.

User with restricted access: Marital Status field is hidden.

Example: Value Set

This example shows the effect of implementing Field Level Security to hide a value set.

In this database the geographic hierarchy is four levels deep (State/City/Suburb/Postcode), but FLS has been used to hide the two lowest levels from some users.

User with full access: hierarchy shows all four levels.

User with restricted access: no access to the two lowest levels.

Example: Field Values

This example shows the effect of implementing Field Level Security to hide the field values.

User with full access: all values of Marital Status available.

User with restricted access: no access to the values Unknown and Not Applicable.

Example: Summation Option

This example shows the effect of implementing Field Level Security to hide a summation option.

User with full access: all summation options available.User with restricted access: no access to Customer Profit option.

When does Field Level Security Take Effect?

If a user has one of the clients open when you apply Field Level Security, the new settings may not take effect immediately:

ClientWhen Does Field Level Security Take Effect?
SuperCROSS

If a user has SuperCROSS open when the settings are applied, then the Field Level Security will not be applied until the user closes and reopens SuperCROSS.

SuperWEB2

If a user has a database open in SuperWEB2 when Field Level Security is applied to that database then the settings will not be applied until the user closes and reopens the database.

  • It is not necessary for the user to log out of SuperWEB2 or restart the browser.
  • It is not necessary to restart the SuperWEB2 service.

Field Level Security settings do not apply to users who are SuperADMIN administrators. Do not attempt to set any Field Level Security settings for these users.

You are recommended not to change the field level security settings for a database once it has gone live in your production deployment. Changing these settings may invalidate saved tables, recodes and user defined fields that users have created for the database.

How Do I Implement Field Level Security?

To learn more about implementing Field Level Security:

  1. Read the Permissions Model - Inheritance and Conflicts to understand how the permissions work together.
  2. Follow the instructions to implement Field Level Security in your system.

Complete Disclosure Control Solution

When implementing a Disclosure Control Solution, Space-Time Research recommends you use Field Level Security in conjunction with the Data Control API and/or mandatory fields.

If you use only Field Level Security for Disclosure Control, you will not necessarily have a complete solution. Field Level Security settings only apply to fields that are part of a cross-tabulation request. Users can still create cross-tabulations that do not contain the controlled field and therefore may still be able to determine some aggregate data about fields.
