Explanation
WPA2 (Wi-Fi Protected Access 2) offers the highest security of the listed options. It uses AES-CCMP (Advanced Encryption Standard with Counter Mode and CBC-MAC Protocol), which is significantly stronger than its predecessors. WEP (Wired Equivalent Privacy) is severely outdated and easily cracked. WPA-PSK uses TKIP, which has known vulnerabilities. WPA-AES is an intermediate improvement but WPA2 supersedes it with mandatory AES and stronger authentication frameworks. WPA2 became the required standard for Wi-Fi certification in 2006.
