Passage One Questions 21 to 25 are based on the following passage: 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 wasnt any crime to worry about. Amazingly, these happy times appear still to be with us in the worlds 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. |
