In groups of three or four, select one of these issues or one assigned by your instructor. After
conducting necessary research, prepare a memo to your supervisor presenting a discussion of
the issue and outlining recommendations for your company.
Your memo should:
1. Establish the purpose of your communication and the overall recommendation you are giving.
SNOOP PROOF YOUR PC
SUMMARY
Ask students to visit the websites indicated on the text support website concerning computer
security and privacy on the Internet.
Assign students Application No. 3 from the case that requires them to summarize the
major snoop risks and what actions can be taken to avoid these risks. Discuss the risks and
solutions in class.
Use this case to prepare students for the Analytical Writing Assignment of the Graduate
Admission Test (GMAT) by having them write an essay relating the use of computers to the Mark
Twain quote presented.
Case
Protecting the security of data files and computer activities is high priority for individuals and
businesses alike. However, your PC is ready and able to reveal not only your data but what
you’ve been doing with your computer. Within a few hours, a snoop can determine and find the
incoming and outgoing mail you deleted, websites you visited, data you’ve entered on web forms,
and even phrases you deleted from documents. Fortunately, you can take steps to protect yourself.
Using effective password protection is a simple first step. Lock important files by using carefully
chosen passwords. The best passwords aren’t real words or dates; they use a combination of
letters, numbers, and punctuation. Knowing how to truly rid your computer of deleted and trashed
files is another important security step. Regularly clearing temporary menus and files, as well as
history listings, will assure that your recent file activities are not recorded for the would-be snoop
to peruse.
An obvious way to protect your information is to encrypt sensitive information. Good
encryption and locking solutions are increasingly user friendly and inexpensive. Numerous
products are available, with the most effective tools encrypting both file contents and passwords
used to access them. Encryption usually defeats casual efforts at intrusion and complicates even
advanced snooping attempts.
Cookies can also provide information from your computer to remote third parties.
Cookies are short pieces of data used by web servers to help identify the user and possibly to
track a user’s browsing habits. Cookies can tell a web server that you have been there before and
can pass short bits of information from your computer to the server. If you are concerned about
being identified or about having your activities traced, set your browser to not accept cookies or
use one of the new cookie blocking packages. Remember, though, that blocking all cookies
prevents some online services from working.
Another potential PC leak that is often overlooked is the discarded hard drive. About
150,000 hard drives are retired each year, but many find their way back onto the market. Stories
occasionally surface about personal and corporate information turning up on used hard drives,
