Authentication Sequence Admin Roles for external administrator accounts can be assigned to an Authentication Sequence, which includes a sequence of one or more Authentication Profiles that are processed in a specific order. The firewall checks against each Authentication Profile within the Authentication Sequence until one Authentication Profile successfully authenticates the user.

You can't filter or sort rules in PoliciesSecurity because that would change the order of the policy rules in the rulebase. Filtering and sorting PoliciesSecurityPolicy OptimizerNo App Specified, PoliciesSecurityPolicy OptimizerUnused Apps, and PoliciesSecurityPolicy OptimizerNew App Viewer (if you have a SaaS Inline Security subscription) does not change the order of the rules in the rulebase.
