72 Securing Your Computer
Smart Cards and Fingerprint Readers
NOTE: The smart card feature may not be available on your computer.
Smart cards are portable credit-card shaped devices with internal integrated
circuits. Using smart cards can improve system security by combining
something a user has (the smart card) with something only the user should
know (a PIN) to provide more secure user-authentication than passwords alone.
A fingerprint reader is a strip sensor located on a peripheral device for your
computer. When you slide your finger over the reader, it uses your unique
fingerprint to authenticate your user identity and help keep your Dell
computer secure.
Passwords
Passwords prevent unauthorized access to your computer. When using
passwords, observe the following guidelines:
• Choose a password that you can remember, but not one that is easy to
guess. For example, do not use the names of family members or pets for
passwords.
• If possible, do not write down your password. If you do write it down,
ensure that the password is stored in a secure location.
• Do not share your password with other people.
• Ensure that people are not watching you when you type your password.
