While probing an organization you discover that they have a wireless network. From your attempts to connect to the WLAN you determine that they have deployed MAC filtering by using ACL on the access points. What would be the easiest way to circumvent and communicate on the WLAN?

  1. Attempt to crack the WEP key using Airsnort.
  2. Attempt to brute force the access point and update or delete the MAC ACL.
  3. Steel a client computer and use it to access the wireless network.
  4. Sniff traffic if the WLAN and spoof your MAC address to one that you captured.

Answer(s): D

Explanation:

The easiest way to gain access to the WLAN would be to spoof your MAC address to one that already exists on the network.



Access control is often implemented through the use of MAC address filtering on wireless Access Points. Why is this considered to be a very limited security measure?

  1. Vendors MAC address assignment is published on the Internet.
  2. The MAC address is not a real random number.
  3. The MAC address is broadcasted and can be captured by a sniffer.
  4. The MAC address is used properly only on Macintosh computers.

Answer(s): C



In order to attack a wireless network, you put up an access point and override the signal of the real access point. As users send authentication data, you are able to capture it. What kind of attack is this?

  1. Rouge access point attack
  2. Unauthorized access point attack
  3. War Chalking
  4. WEP attack

Answer(s): A

Explanation:

The definition of a Rogue access point is:1. A wireless access point (AP) installed by an employee without the consent of the IT department. Without the proper security configuration, users have exposed their company's network to the outside world.2. An access point (AP) set up by an attacker outside a facility with a wireless network. Also called an "evil twin, " the rogue AP picks up beacons (signals that advertise its presence) from the company's legitimate AP and transmits identical beacons, which some client machines inside the building associate with.
