Compile a checklist of names of students expected to attend - insist that each name is checked against the guest list before an individual is allowed to enter the party.
Parents/security guard should be at the entrance to check invitations before allowing entry.
Regardless of invitation, be firm when preventing access to the party to students who are already seriously inebriated or who are behaving badly.
