In an attempt to secure his 802.11b wireless network, Bob decides to use strategic antenna positioning. He places the antennas for the access points near the center of the building. For those access points near the outer edge of the building he uses semi-directional antennas that face towards the buildings center. There is a large parking lot and outlying field surrounding the building that extends out half a mile around the building. Bob figures that with this and his placement of antennas, his wireless network will be safe from attack. Which of the following statements is true?
A.
Bob’s network will be safe but only if he doesn’t switch to 802.11a
B.
With the 300-foot limit of a wireless signal, Bob’s network is safe
C.
Wireless signals can be detected from miles away; Bob’s network is not safe
D.
Bob’s network will not be safe until he also enables WEP
Explanation:
It’s all depending on the capacity of the antenna that a potential hacker will use in order to gain access to the wireless net.
