About this task
In addition to defining the iH Tag Admins who have the power to
create, modify, and remove tags, you can also define individual tag level security to
protect sensitive tags. 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.
Note: Tag security is not enforced in the Trend Client when it comes to browsing the full list of tags. Security, however, is enforced
when it comes to trending data for tags for which you have permission. For example,
if you are logged into the Trend Client as a user that is a member of the User Group assigned to a tag's security Read
Group, you will still be able to browse all Historian tags. However, you are only
allowed to trend the tags for which the user is a member of the User Group assigned
to the tag's security Read Group,
