In an attempt to secure his 802.11b wireless network, Ulf decides to use a strategic antenna
positioning. He places the antenna 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 building’s center. There is a large parking lot and outlying filed surrounding the
building that extends out half a mile around the building. Ulf 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.
With the 300 feet limit of a wireless signal,Ulf’s network is safe.
B.
Wireless signals can be detected from miles away,Ulf’s network is not safe.
C.
Ulf’s network will be safe but only of he doesn’t switch to 802.11a.
D.
Ulf’s network will not be safe until he also enables WEP.
B or D
Um…. How would enabling WEP be “safe”…?
If your wireless equipment only supports WEP (which probably is the case with NICs being deployed with the older 802.11b standard)then I guess weak encryption is better than no encryption at all. B does have some merit, but this cannot supersede having encryption present – I’ll vote D.
D
assuming that he didn’t enable encryption at all
