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.
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 networks in operation.
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.
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.
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.
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.
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.
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.
Raymond Kruck most probably agrees that wireless network security involves
选项
A、wireless signal administration.
B、changes in users’ awareness.
C、users’ psychological health.
D、stronger physical walls.
答案
B
解析
第6段首句中的psychological表明Kruck认为网络的安全问题与人们的想法有关,人们只认为有形的墙就是安全的,但忽略了网络的范围是不受有形的墙体限制的,由此可见,网络的安全有赖于人们改变这种观念,因此本题应选B。本题最具干扰性的是C。原文中的psychological problem并不是指使用无线网络的人有心理问题,而是指网络安全是与人们的心理有关的问题,因此,不能说网络安全有赖于人们健康的心理。
