They may be just passing your office, computer bag slung (悬挂) over one shoulder. Or they may be sitting in a car outside it, causally 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 (巡逻) 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（加密）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 legal users.
Most companies using wireless networking technology do not take even the simplest of measures to protect their data. Nearly all wireless network technology comes with some basic security features that need only to be activated (激活) in order to give a minimum level of security, for example, by encrypting the data being passed over the network.
Raymon 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 safeguards 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 ridiculously 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 (默认) 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.

President Coolidge’s statement, “The business of America is business,” still points to a very important truth today — that business organizations have more prestige (威望) in American society than any other kind of organization, including the government. Why do business institutions still possess this great prestige?
One reason is that Americans view business as being more firmly based on the idea of competition than other organizations in society. Since competition is seen as the main source of progress and development by most Americans, competitive business organizations are respected. Competition is not only good in itself; it is the means by which other basic American values, such as individual freedom, equality of opportunity, and hard work are protected.
Competition protects the individual freedom by making sure that there is no monopoly (垄断) of power. Compared with one and all-powerful government, many businesses compete against each other for benefit. If one business tries to take unfair advantage of its customers, it will lose to the competing business which treats its customers more fairly. Since there are many businesses competing for the customers’ dollars, they cannot afford to treat them unfairly and the customers would lose nothing.
A contrast is often made between business, which is competitive, and government, which is a monopoly. Because business is competitive, many Americans believe that it gives more support for freedom than government, even though government leaders are elected by the people while business leaders are not. Many Americans believe that competition is as important, or even more important, as democracy in protecting freedom.
Competition in business is also believed to strengthen the idea of equal opportunities. Competition is seen as an open and fair race where success goes to any person regardless of his or her social class background. Competitive success is commonly seen as the American choice of the higher social position which is not based on one’s family background. Business is therefore viewed as an expression of the idea of equal opportunities.
1.Which of the following is discussed as the main topic in the passage?
A. Competition in America’s business. B. Freedom in America’s business.
C. Americans’ different values. D. Business against government.
2. Americans believe that they can realize their personal values ______.
A. when given equal opportunities
B. through doing business
C. by protecting their individual freedom
D. by means of competition
3.Who can benefit from business competition?
A. Businessmen who compete.
B. Customers of those businesses.
C. People with the idea of equality and freedom.
D. Both business organizations and government.
4.It could be inferred from the passage that the author believes ______.
A. business in other countries are not as competitive as those in the USA
B. business problems are very important to the American government
C. the competition in business plays a very important role in America
D. American business is the most powerful one in the whole world
