Implementing Tag Level Security
About this task
Set tag level security in Historian Administrator. You need the Historian Security Groups to implement tag-level security. You can use a Windows pre-defined group (power users, for example) or create your own separate group specifically for this function. For more information on creating and adding groups, refer to Setting Up Historian Security Groups.
Users must have iH Security Admins rights to set individual tag level security, browse, or query tags in Historian Administrator.
Procedure
- Open Historian Administrator.
- Select the Tags link. The Tag Maintenance page appears.
- Select a tag (or group of tags) from the Tag Name section of the Tag Maintenance page.
- Select Advanced to display the advanced tag options.
-
In the Read Group, Write Group,
or Admin Group field, select the security group that you
wish to assign to the tag from the drop-down list.
The drop-down list automatically lists all security groups that are defined in your Windows security environment.For example, if an iH Security Admins user selects a tag and chooses power users from the Read Group drop-down list, in addition to members of the iH Security Admins group, only a member of the power users group will be able to read data for that tag. Even a member of the iH Readers group will not be able to access data for that tag, unless they are also defined as a member of the power users group.Note: If you are using domain groups (instead of local groups), the Read Group, Write Group, and Admin Group fields contain only the groups whose names begin with iH<space> (case-sensitive). Therefore, ensure that the group that you want to use begins with iH<space>.
