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.
