(1)They may be just passing your office, computer bag slung over one shoulder. Or they may be sitting in a car outside it, casually tapping away at a laptop. They look like innocent passers-by. In fact, they are stealing your corporate secrets.
(2)Drive-by hacking is the trendy term given to the practice of breaking into wireless computer networks from outside the buildings that house them. A recent study in the UK, sponsored by RSA Data Security, found that two-thirds of organizations with wireless networks were risking their data in this way. Security experts patrolled several streets in the City of London seeking evidence of wireless net-Works in operation.
(3)Of 124 that they identified, 83 were sending data without encrypting them. Such data could readily be picked up by a passer-by armed only with a portable computer, a wireless modem and a few pieces of software that can be freely downloaded from the Internet.
(4)The data could include sensitive company documents containing valuable information. Or they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legitimate users.
(5)Most companies using wireless networking technology do not take even the simplest of precautions to protect their data. Nearly all wireless network technology comes with some basic security features that need only to be activated in order to give a minimum level of security, for example, by encrypting the data being passed over the network.
(6)Raymond Kruck, business development manager at Check Point Software, a security technology specialist, believes this could be partly a psychological problem. People see the solid walls of their building as bulwarks and forget that wireless networks can extend up to 200 meters beyond physical walls.
(7)Companies without any security at all on their wireless networks make it risibly easy for hackers to break in. Switching on the security that comes with the network technology should be automatic. Then there are other basic steps a company can take, says Mr. Kruck, such as changing the passwords on the network from the default setting.
(8)Companies can also install firewalls, which form a barrier between the internal network and the public Internet. They should also check their computer records regularly to spot any abnormal activity, which might betray the presence of a hacker.
Which of the following is not considered in the study?
选项
A、The number of wireless hacking incidents.
B、The number of wireless computer networks.
C、The way in which data are sent and received.
D、The way in which data are hacked and stolen.
答案
A
解析
根据题干中的study可以知道本题涉及的段落较多。第2、3段概括性地介绍了研究结果,从这两段所述可以知道只有A的内容没有包括在研究的范围内。根据第3段首句中的数字就可以知道B是研究的内容之一;同时,该句中的encrypting涉及数据传输过程,因数据传输的方式包括是否有将数据加密,可见C也是研究内容;第3段第2句提到的很轻易窃取数据的方法表明D也包括在研究内容里面。
