You can export a security rule set to an XML file to back up security rule definitions. Additionally, you can use the export utility to make a copy of a rule set and import the copy to the security rule tree. You might want to make a copy if you have a complex rule set structure that you want to reuse. Exported security rule sets retain the tree rule structure.
An exported file contains the components of a security rule set, such as the rule folders, security rule matchers, actions, and processing actions for each rule in the rule set.
