After you create your data grids, the security of the data grid is disabled by default.
You can change the security settings for a data grid to restrict access to
a certain user or group of users.
About this task
Important: When you change the security settings
for a data grid, the data grid automatically restarts. When the data
grid is restarted, any data that is in the data grid is lost. Configure
the security for your data grids before you begin to save data in
the data grid.
Procedure
- In the user interface, navigate
to the data grid settings. Click . Click the data_grid_name that
you want to edit.
- Enable security or authorization for the data grid. Click Enable
security to enable any user that has access to the user interface to access the data grid. If you want to further
restrict access, click Enable authorization.
With authorization enabled, you can specify a list of users or user
groups in the Access granted to list. When enable
authorization is selected, only users that are listed in this access
list can access the data grid data.
When
you change the security and authorization settings, there is a timeout
value of five minutes.
- Authentication timeout: If you change a user password for
a user that has already been authenticated to the data grid, the original
credential is still valid for up to five minutes.
- Authorization timeout: If you remove a permission for a
user, that user continues to have the permission for up to five minutes. This
timeout applies only for permissions that are removed. If you add
a permission to a user, the user gets the permissions immediately.
