Once you complete your security strategy, the next step is to define your security areas and specify a name for each area. You can define up to 254 security areas, and each name can be up to 20 characters. iFIX names the first 16 security areas A through P by default. However, you can rename these areas or create a new area by clicking the Security Area button on the Security toolbox. After you define a security area, you can assign it to a group or user account.
Use the Tag Security Areas drop-down in the Security Area Naming dialog to specify how security areas assigned to a tag are evaluated when a user writes to a tag or acknowledges a tag’s alarm. There are two evaluation options:
- Require At Least One (OR) - Users require access to at least one specified security area.
- Require All (AND) - Users require access to all specified security areas.
NOTE: You must re-start iFIX on the SCADA(s) using that Security Path (as in the case of shared security files) for this setting to take effect.
