You can import a security rule set into the rule tree or into a rule folder. When you import a rule set, the rule tree displays the original structure of the rule set. After you import the security rules, save and update the rule set to the rule tree.
Before you import a security rule set, create an empty security rule set in the rule tree. Rules that you import appear in this rule set. If you import security rules into a rule set that is not empty, the imported rule set overrides the existing rule set.
You can also import a rule set into a rule folder that is part of an existing rule set.
