What are three security problems with Wi-Fi Protected Access (WPA)?()
A

WPA is based on the outdated IEEE 802.11i standard.

B

WPA uses RSN,which uses the same base encryption algorithm as RC4.

C

WPA requires a hardware upgrade that may not be supported by all vendors.

D

WPA uses TKIP,which uses the same base encryption algorithm as WEP.

E

WPA is susceptible to a DoS attack when it receives two packets in quick succession with bad MICs,forcing the AP to shut down the entire Basic Service Set (BSS) for one minute.

F

WPA is susceptible to a security weakness when preshared keys are used.
