HistorianAbout Protecting Your Process
If you want to restrict access to Historian archives, files, and tags, or protect your data files from unauthorized changes, you can enable Historian security. Using security is optional and is disabled by default. By enabling security, you can restrict access to:
- Modifying data using Excel Add-In
- Updating security for individual tags or groups of tags
- Creating, modifying, and removing tags
- Tag protection (adding, modifying, removing, and so on) can be applied at a global level to all tags or at the individual tag level.
Refer to Implementing Tag Level Security for more information.
- Reading data in the iFIX Chart object, Excel Add-In, and Migration Utilities
- Writing data
- Starting and stopping collectors
- Creating and deleting collectors
- Creating, modifying, and deleting archives
Historian uses the operating system security groups to create a security structure. You can enable security for a particular set of functions by adding specific Historian Security Groups to your groups. You can also add security groups to your domain controller.
By defining one or all of the groups, you begin to set up a security structure. Refer to the Historian Security Groups section for more information on the Historian Security Groups available.
