A wireless administrator sets up a new network in a small office using a password.

SAE, or Simultaneous Authentication of Equals, is the correct answer. SAE is used with WPA3-Personal and replaces the weaker pre-shared key exchange approach used in earlier WPA versions. Its major security benefit is resistance to offline dictionary and brute-force attacks after over-the-air capture. With older WPA/WPA2-PSK handshakes, an attacker could capture the handshake and repeatedly test guessed passwords offline. SAE changes the authentication exchange so captured traffic is not useful in the same way for mass offline guessing. WIPS can detect or prevent wireless intrusions, but it does not directly strengthen the password authentication exchange. SSO is an identity convenience mechanism, and WPS is a risky setup feature historically associated with PIN brute-force weaknesses.
