PASSWORDS FOR YOUR PROTECTION


Information
Technology (IT)
specialists, also called Network
Administrators, must manage and protect network accounts
from both accidental mistakes and deliberate abuse.


A password is a series of letters and/or numbers that users
enter to gain access to their network account. These
passwords protect your
data
from unauthorized use by others.


Hackers

are unauthorized users who steal confidential data,
such as credit card information.


A
computer
virus

is a
program
that can quickly destroy data
and may cause a computer or network to stop working
properly. A
virus can run without the user’s knowledge.

PERFECTLY PROPER PASSWORDS

Rule 1:

Do not create an obvious password that nearly anyone who
knows you can easily guess, such as birthdate or a pet’s name.

Rule 2:

Make your password at least eight characters or longer. Do
not, however, create an unnecessarily long password. A well
-
chosen shorter password can be just as secure as a longer one.

Rule 3:

Your password will be more secure if you use a combination
of letters and numbers.

Rule 4:

Do not forget your password! Think of something that will
help you remember it but do not write it down.

Rule 5:

Do not share your password with anyone
