All about Cookies
Figure 1.9 - Deleting cookies is a good idea for security
Deleting cookies manually may be a bit of a
pain. However, if it saves the user from having to deal with
financial fraud or identity theft, it is worth the extra effort.
If the computer is one that is shared, when the
user is finished with their task, they should delete all cookies
before leaving their workstation. If the computer is a laptop or
portable computer, then erasing cookies is even more important
because if stolen, the thieves could go on a shopping spree using
the credit card information left in cookie form.
There are companies that sell programs called
cookie managers. These programs allow the user to control which
cookies they want to keep and which ones they want to delete. One
of the best features of this type of program is its ability to alert
the user every time a cookie is left on their computer. It is very
insightful to realize just how often this happens.
Most people are unaware that it is not
necessary for them to manually enter personal information in order
for another computer to extract that information. Some commonly
used web browsers maintain a user profile of the person running the
browser as well as information about the computer on which it is
running. If another computer on the network requests information in
the proper format, the browser may provide the data requested behind
the scenes. The user will not be asked to authorize the data
transfer, and in fact, will probably not be aware it is happening.
