A network administrator is setting up a new wireless network for a corporate office. The requirements are to use the highest level of security available, provide strong protection against offline dictionary attacks, and ensure that even if a password is compromised, previously captured traffic remains secure. Which wireless security protocol should the administrator implement to meet these requirements?
WPA3 is the correct choice as it provides the most robust security for modern wireless networks. It introduces Simultaneous Authentication of Equals (SAE) to protect against offline dictionary attacks, a significant vulnerability in WPA2's PSK mode. WPA3 also provides forward secrecy, meaning that even if a password is stolen, it cannot be used to decrypt previously intercepted data traffic. WEP is outdated and insecure, WPA is also considered legacy, and while WPA2 is still widely used, it is susceptible to attacks like KRACK and does not offer the same level of protection as WPA3.
