Protecting Sensitive Online Data

whether you want to block all third-party cookies or be prompted to accept
them. If you select the Prompt option, a dialog box notifies you that each

Now that you have set the cookie privacy setting manually, you can eliminate
cookies from being stored on your hard drive in the first place. Doing so allows
you to protect your privacy and still be able to use websites that need cookies.
Protecting Sensitive Online Data
If you manage your finances or shop online, you probably have had experience
with using secure web connections, otherwise known as Secure Sockets Layer
SSL) . These secure connections encrypt the data that is transferred to and from (
a web server and your computer. After the data gets to your computer, your
browser has a special key that decrypts the information and displays it on your
computer. During this process, when the file is decrypted, it is saved in the
Temporary Internet Files directory so that the browser can display it.
This default appears to be harmless because the web page is saved on your
computer only. If no one has remote access to your computer, the data is safe,
right? Not necessarily, because your data is now vulnerable to anyone who has
physical local access to your computer. If that person is clever and lucky enough,
he or she can sort through your Temporary Internet Files directory and just might
find some confidential information such as your online banking information.
All this information is saved by default on your hard drive for anyone to see
if they know how to get to it. They do not even need to know your password
or log on to your account on the bank’s website because a snapshot of the web
page is stored locally on your computer.
What can you do to protect your computer from this vulnerability besides
setting up better security such as complex passwords? Internet Explorer offers
a cool feature that you just have to turn on to eliminate this problem completely.
Simply called Do Not Save Encrypted Pages To Disk, this feature prevents your
computer from storing the encrypted data. To enable it, follow these steps:
1. Open Internet Explorer.
2. Click the gear icon and click Internet Options.
3. Click the Advanced tab.
4. Scroll down through the list toward the bottom of the window until you
see the Security section.
