With the development of the society, especially the development of economy, the life both in countryside and city changes a lot. Who are still dwelling on the old life? 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 side. Given the lack of locks, the Internet is surely the world’s big gest(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.
Farmer’s program has been criticized by the public because______.
选项
A、it causes damage to Net browsers
B、it can break into Internet sites
C、it can be used to cause disorder on all sites
D、it can be used by people with evil intent
答案
D
解析
事实细节题。用查读法找到第三段第二,三句,就是本题的答案:Farmer使这个程序能公开买到,这引起许多批评。因为一个心怀叵测的人可以用它去寻找那些容易闯入进行行窃的网站。所以选项D是正确答案。
