The Internet began in the 1960s as a small network of academic and government computers primarily involved in research for the U.S. military. Originally limited to researchers at a handful of universities and government facilities, the Internet has quickly become a worldwide network providing users with information on a range of subjects and allowing them to purchase goods directly from companies via computer. By 1999, 84 million U.S. citizens had access to the Internet at home or work. More and more Americans are paying bills, shopping, ordering airline tickets, and purchasing stocks via computer over the Internet.
Internet banking is also becoming increasingly popular. With lower overhead costs in terms of staffing and office space, Internet banks are able to offer higher interest rates on deposits and charge lower rates on loans than traditional banks. "Brick and mortar banks" are increasingly offering online banking services via transactional websites to complement their traditional services. At present, 14 percent of Internet households conduct their banking by means of the Internet, and the figure is expected to double or triple during the next two or three years.
Increasing commercial use of the Internet has heightened security and privacy concerns. With a credit or debit card, an Internet user can order almost anything from an Internet site and have it delivered to their home or office. Companies doing business over the Internet need sophisticated security measures to protect credit card, bank account, and social security numbers from unauthorized access as they pass across the Internet. Any organization that connects its networks to the global Internet must carefully control the access point to ensure that outsiders cannot disrupt the organization’s internal networks or gain unauthorized access to the organization’s computer systems and data.
The last sentence of the third paragraph tells us that______.
选项
A、any organization’s networks may be at risk of security breaches
B、current technology cannot safeguard against unauthorized access to online networks
C、information security should be a pressing concern for Internet commerce
D、organizations must secure their networks and data against unauthorized use
答案
D
解析
属信息推断题。本文第三段最后一句指出:任何机构若将其内部网络与全球因特网相连,则必须严密控制衔接点,以确保外人无法扰乱机构内部网络,也不能未经许可而进入其计算机系统,接触数据。符合此意的只有选项D,选项A中的any表达太绝对;选项B的内容文中没有提到;选项C的内容主要针对第三段前三句,与最后一句的联系并不紧密。
