Cookies
A file placed on your hard drive by a Web site you visit. The original intent is
for cookies to contain information about your preferences, so they can tailor
the appearance according to your needs. This saves time when you visit the
site the next time.
The security risk with cookies is that, since they are written directly to the hard
drive, they can store something dangerous (e.g., virus) or private (e.g.,
password). There is also concern that one Web site can get a cookie created by
another Web site. It appears that cookies cannot be used to get other data from
a user's hard drive (e.g., applications used, database, address book, personal
files, etc.). Cookies can also be used to track where a user has been within a
Web site.
Netscape Navigator can be set to prompt you whether or not you want to
accept a cookie. It is recommended that you do not accept cookies unless you
have a reason for doing so.
