Because a wireless signal is not confined to the four walls of the building, an unauthorized user can often pick up the signal outside the building’s security perimeter. It is possible for an intruder to be lurking in the parking lot with a wireless laptop computer to intercept the signals and access the network. Once on the network, the intruder could read sensitive documents or infect the entire network with malicious software. ● Attackers can eavesdrop on transmissions. In a wired network, an attacker would have to gain access to the interior of the building to reach the network cabling infrastructure before he could access the network to eavesdrop on data being transmitted.
