Given: You are the network administrator for ABC Company. Your manager has recently attended a wireless security seminar. The seminar speaker insisted that a wireless network could be hidden from potential intruders if you disabled the broadcasting of the SSID in Beacons and configured the access points not to respond to Probe Request frames that have a null SSID field. Your manager asks your opinion about these security practices. How would you respond? Choose 2

A.
Any 802.11 protocol analyzer can see the SSID in clear text in frames other than Beacons and Probe Response frames. This negates any benefit of trying to hide the SSID by configuring Beacons and Probe Response frames.

B.
These security practices prevent manufacturers’ client utilities from seeing the SSID. This means that the SSID cannot be obtained, except through social engineering, guessing, or use of WIPS.

C.
Broadcasting the SSID in Beacons and allowing access points to respond to Probe Request frames with null SSID fields allows authorized users to easily find and connect to the WLAN, provided they have the correct security credentials.

D.
Any tenants in the same building using a wireless intrusion protection system (WIPS) will be able to obtain the SSID by exploiting probe delay timers. This poses a security risk.

E.
An additional security practice is equally crucial to hiding the wireless network’s SSID:deauthentication frames. The access point and client stations must both be configured to remove the SSID from Deauthentication frames.
