Removing Permissions from a User Group or User Account

To control access to an item's features and data, you need to allocate permissions to the various User Groups and user accounts on your system. You can allocate permissions via the Security window.

Depending on your system requirements, you may need to remove some User Groups or user accounts from the permissions for certain database items. For example, if you want to stop some items from being viewed via the Guest user account on a WebX client, you need to remove the Web user from the security settings for the database items.

To remove permissions from a User Group or user account:

1. Display the Database Bar (see Display an Explorer Bar in the ClearSCADA Guide to ViewX and WebX Clients).
2. In the Database bar, right-click on the database item for which you want to define the security settings.
   A context sensitive menu is displayed.
3. Select the Edit Security option to display the Security window.
4. Select the User Group or user account for which you want to remove the security permissions from the list on the Security window.
5. Select the Remove button.
   The User Group or user account is removed from the list. The User Group or user account will now have no access to the selected database item.
6. Select the OK button on the Security window to confirm your selections.

NOTE: If you remove the permissions for a user account, that user account will still be able to access the item if it is part of a User Group that has access permissions. This applies to every User Group, including the default 'Everyone' User Group. For example, if the 'Everyone' User Group provides access to a point, every user account (apart from the Guest user) will have access to the point, even if you have removed the individual user accounts from the point's security settings. To deny access to an item, you need to remove the 'Everyone' User Group from its security settings.

NOTE: When you change permissions, certain menu options will remain visible to users even if they do not have the permissions to use them. If the users attempt to use such options, an Access Denied message box is displayed. If the users log off and then log on again, those options to which they do not have access will no longer be displayed.
