Adjusting Your Cookie Security Policy
Cookies are also created on your computer when you visit websites. Contrary
to popular belief, cookies are not all bad. Most websites use them to save user
data to a browser. An example of this is automatic site logon when you visit
a website. A website you visit can detect whether a cookie that has your user
ID stored in it already exists from a previous visit to that site. If it finds one, it
knows exactly who you are and logs you on automatically. Advertisers also use
cookies to store personal data. Instead of showing you the same advertisement
50 times, they use cookies to keep track of how many times an advertisement
is displayed on your screen.
However, some advertisers abuse what are called third-party cookies to track the
websites you visit and then deliver relevant ads based on what you do online.
Because of the abusers, it is best to just delete all your cookies on a regular basis
because it is hard to separate the good from the bad. I show you more about
how to protect against third-party cookies in the next section.
Clearing the temporary Internet files, history, and cookies is a very simple
task. Just follow these steps to clear these files:
1. When Internet Explorer is open, hit Ctrl+Shift+Delete.
2. On the Delete Browsing History screen, check all items except Preserve
Favorites Website Data, as shown in Figure 20-2.
3. Click Delete and all will be deleted.
Now users can no longer see which websites you visit from the cookies and
temporary Internet files that are stored on your computer. Additionally, you
have freed up some disk space by deleting these files.
Adjusting Your Cookie Security Policy
As mentioned, cookies are not as bad as some people in the computing world
would like you to believe. Instead, the only real risk they present is a loss of
some privacy. If you allow your browser to accept cookies, your PC will have
quite a collection of them over time. Anyone who uses your computer can
discover which sites you visited, if they know where the cookie files are located.
The latest version of Internet Explorer includes many new enhancements.
One of the enhancements includes a new way of accepting cookies. Now you
have the capability to specify whether you would like your browser to block
all cookies or just certain types of cookies. To use this new feature, you need to
understand the two different types of cookies:
First-party cookies —Placed on your computer by the current site that
you are visiting.
Third-party cookies —Placed on your computer by remote sites, such as
advertisement servers.
