You can protect the script of rules and checks either at the rule set level or at the rule and check one.
You can automatically protect your scripts using the Protect Content command. When using the command at a rule set level, the script of rules and checks contained in the rule set are automatically protected.
This capability has been improved on this release. If you protected your scripts on a lower level, you may be asked to upgrade to the new method.
Important:
Once the object is in protected mode, it cannot be made visible again. This state is definitive.
To protect your script, right-click the object
and select Protect Content.
