Given:ABC Corporation’s 802.11 WLAN is comprised of a redundant WLAN controller paid and 30-access points. ABC implemented WEP encryption with IPSec VPN technology to secure there wireless communication because it was the strongest security solution available at the time it was implemented. IT management has had decided to upgrade the WLAN infrastructure and implement VoWiFi and is connected with security because most VoWiFi phones do no support IPSec.
As the wireless network administrator, what new security solution would be best for protecting ABC’s data?
A.
Migrate to a new multi=factor security solution using WPA-2 personal, MAC filtering, SSID holding, stateful packet inspection and RBAC.
B.
Migrate corporate data clients to WPA-Enterprise and segment VoWiFi phone by assigning them to a different frequency band.
C.
Migrate corporate data and VoWiFi devices to WPA-2 Enterprise with OKC support, and segment VoWiFi data on separate VLAN.
D.
Migrate all 802.11 data and devices to WPA-personal, and implement a secure DHCP server to allocate addresses from a segment subnet for the VoWiFi phones.
E.
Migrate corporate data clients to WPA-2-Enterprise, and use the RADIUS server to implement MAC-base authentication of VoWiFi phones.
Explanation:
WPA-Enterprise: Also referred to asWPA-802.1xmode, and sometimes justWPA(as opposed to WPA-PSK). Is designed for enterprise networks, and requires a RADIUS authentication server.http://en.wikipedia.org/wiki/Wi-Fi_Protected_Access
RADIUS Based MAC authentication authenticates a wireless client with a RADIUS server based on the MAC address of the client; this is useful for clients with minimal or no user interface. http://docs.google.com/viewer?a=v&q=cache:eIGtVa7SnLMJ:h18000.www1.hp.com/products/quic kspecs/13271_div/13271_div.PDF+use+the+RADIUS+server+to+implement+MAC- base+authentication+of+VoWiFi+phones&hl=en&gl=in&pid=bl&srcid=ADGEESjQH2m9b74LLUJk u5awkwNdahLshS_bHHCO8rtQYv9TLDrxFyhzVIte_9VW_aFu7VgJusALDWqkdm8MiG2y823wVR D1PLljPd6WPmjR5BVojaugVZmMQ7dwJT-
