SECURITY PROBLEMS AND NON-PROBLEMS ON THE WEB
© 1999 Virginia Lawrence, Ph.D.
Occasionally the bad guys on the Web can pose some danger to the security of
the files on your computer. More often, concern is unnecessary. Read on for two
examples.
Internet Explorer Bug Lack of security arises
through loopholes in your browser software. According to PC Week, there
is a bug in Internet Explorer 4.0. This bug allows hackers to access a user's
hard drive files. Worse, the bug allows hackers to run code on a user's
computer.
This is a potentially disastrous bug. All IE 4.0 users should use IE 3.0 or
Netscape 4.0 until Microsoft releases the software patch. If you prefer to live
dangerously, use IE 4.0 and be sure to avoid any URL line address which
includes "mk:".
Cookies From Strangers? Cookies on the World
Wide Web aren't chocolate chip. You get a cookie when a Web page sends a small
data file to your computer. The Web site software later reads its cookie to
identify you in some way.
Amazon.com uses cookies to keep track of customers and shopping carts. The
New York Times site uses a cookie to store your password, but only after
requesting permission. Ad banners use cookies to track the number of viewers
for each banner at a site, along with the number of people who click on that
banner.
So cookies are useful to Web marketers and harmless to you. A cookie
contains only the information placed in it by the Web page software. And that
information can be read only by the placing page.
