Question

A parks AP lists 'Open System authentication' alongside WPA2 in the controller summary. What does that combination mean for confidentiality?

Accepted Answer

Open System authentication is common even on encrypted networks; actual confidentiality comes from RSN keying — Open System here is just the polite handshake at the door—not the deadbolt. WPA2 still locks the room with RSN keys after that hello. Do not panic that the label says 'Open' when the cipher suite is doing the real secrecy work.

Answer
