CWSP Certified Wireless Security Professional: CWSP-206

XYZ Company has recently installed a controller-based WLAN and is using a RADIUS server to query authentication requests to an LDAP server. XYZ maintains user-based access policies and would like to use the RADIUS server to facilitate network authorization. What RADIUS feature could be used by XYZ to assign the proper network permissions to users during authentications?

A. RADIUS can reassign a client's 802.11 association to a new SSID by referencing a username-to-SSID mapping table in the LDAP user database.

B. The RADIUS server can support vendor-specific attributes in the ACCESS-ACCEPT response, which can be used for user policy assignment.

C. The RADIUS server can communicate with the DHCP server to issue the appropriate IP address and VLAN assignment to users.

D. RADIUS can send a DO-NOT-AUTHORIZE demand to the authenticator to prevent the STA from gaining access to specific files, but may only employ this in relation to Linux servers.

While seeking the source of interference on channel 11 in your 802.11n WLAN running within 2.4 GHz, you notice a signal in the spectrum analyzer real time FFT display. The signal is characterized with the greatest strength utilizing only 1-2 megahertz of bandwidth and it does not use significantly more bandwidth until it has weakened by roughly 20 dB. At approximately -70 dB, it spreads across as much as 35 megahertz of bandwidth. What kind of signal is described?

A. A high-power ultra wideband (UWB) Bluetooth transmission.

B. A 2.4 GHz WLAN transmission using transmit beam forming.

C. A high-power, narrowband signal.

D. A deauthentication flood from a WIPS blocking an AP.

E. An HT-OFDM access point.

F. A frequency hopping wireless device in discovery mode.

For a WIPS system to identify the location of a rogue WLAN device using location pattering (RF fingerprinting), what must be done as part of the WIPS installation?

A. A location chipset (GPS) must be installed with it.

B. At least six antennas must be installed in each sector.

C. The RF environment must be sampled during an RF calibration process.

D. All WIPS sensors must be installed as dual-purpose (AP/sensor) devices.
