Question No : 6

To ease user complexity, your company has implemented a single SSID for all employees.
However, the network administrator needs a way to control the network resources that can be accessed by each employee based in their department.
What WLAN feature would allow the network administrator to accomplish this task?

A.RBAC
B.SNMP
C.WIPS
D.WPA2

정답:

Question No : 7

Question No : 8

You are the network administrator for ABC Company. Your manager has recently attended a wireless security seminar. The seminar speaker taught that a wireless network could be hidden from potential intruders if you disable 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 suggests implementing these security practices.
What response should you give to this suggestion?

A.Any tenants in the same building using advanced penetration testing tools will be able to obtain the SSID by exploiting WPA EAPOL-Key exchanges. This poses an additional risk of exposing the WPA key.
B.Any 802.11 protocol analyzer can see the SSID in clear text in frames other than Beacons frames. This negates any security benefit of trying to hide the SSID in Beacons and Probe Response frames.
C.To improve security by hiding the SSID, the AP and client stations must both be configured to remove the SSID from association request and response frames. Most VLAN products support this.
D.This security practice prevents manufacturers’ client utilities from detecting the SSI
E.As a result, the SSID cannot be obtained by attackers, except through social engineering, guessing, or use of a WIP
