A county parks department shares one WPA2-Personal passphrase across maintenance tablets. After a staff laptop is stolen with the passphrase saved, offline cracking of captured handshakes becomes a realistic risk. Which mitigation best reduces that cracking exposure going forward?
Select an answer to reveal the explanation.
Short Explanation
A weak shared Wi-Fi password is like one master key under every parks truck mat—steal one device and the whole lot opens. Lengthen and randomize the PSK, move to SAE/WPA3-Personal when you can, or better yet give each tablet real Enterprise auth so one stolen secret is not the whole kingdom.
Full Explanation
Offline PSK cracking exploits captured 4-way handshakes against weak shared secrets. Long, high-entropy passphrases raise cracking cost; WPA3-Personal SAE resists offline dictionary attacks better than classical PSK; Enterprise authentication removes a single shared passphrase entirely. Cosmetic measures such as hiding the SSID or weakening crypto do not mitigate cracking risk.
