How can I add an administration section?

I want to add an administration section to the bottom of a form I'm looking to create for a reservation process.  This would include information that is more for internal purposes and would not be easily filled in by the user filling out the form.  I would like to restrict this section, so other users do not accidentally add/change information.  Is there a way to configure security so only an administrator can enter in those fields?

The easiest way to do add an admin section would be to have a section collapse above the admin fields then conditionally show the form collapse.  Here is more information regarding how to do so:

The condition could be based on a short text field entry so that a specific word needs to be entered in order to see the collapsed section.
