单选题 In the villages of the English countryside there are still people who remember the good old days when no one bothered to lock their doors. There simply wasn"t any crime to worry about. Amazingly, these happy times appear still to be with us in the world"s biggest community. A new study by Dan Farmer, a gifted programmer, using an automated investigative program of his own called SATAN, shows that the owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors.
SATAN can try out a variety of well-known hacking tricks on an Internet site without actually breaking in. Farmer has made the program publicly available, amid much criticism. A person with evil intent could use it to hunt down sites that are easy to burgle.
But Farmer is very concerned about the need to alert the public to poor security and, so far, events have proved him right. SATAN has done more to alert people to the risks than cause new disorder.
So is the Net becoming more secure? Far from it. In the early days, when you visited a Web site your browser simply looked at the content. Now the Web is full of tiny programs that automatically download when you look at a Web page, and run on your own machine. These programs could, if their authors wished, do all kinds of nasty things to your computer.
At the same time, the Net is increasingly populated with spiders, worms, agents and other types of automated beasts designed to penetrate the sites and seek out and classify information. All these make wonderful tools for antisocial people who want to invade weak sites and cause damage.
But let"s look on the bright side. Given the lack of locks, the Internet is surely the world"s biggest (almost) crime-free society. Maybe that is because hackers are fundamentally honest. Or that there currently isn"t much to steal. Or because vandalism isn"t much fun unless you have a peculiar dislike for someone.
Whatever the reason, let"s enjoy it while we can. But, expect it all to change, and security to become the number one issue, when the most influential inhabitants of the Net are selling Services they want to be paid for.

单选题 By saying "...owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors" (Lines 5-6, Para. 1), the author means that ______.

【正确答案】 C

【答案解析】[解析] 细节题。根据题干定位到第二段。the owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors这是个比喻句，字面意思是“万维网一半多的主人建立了不上锁的家”，作者把网站比作家，把网站的建立者比作家的主人，把网站采取的安全措施比作门上的锁，这句话的意思就是大部分网站都没有采取安全措施。因此C项为正确答案。
