Create & Maintain a Secure Password

Contents
Passwords are an important aspect of computer security.
They are the defensive frontline that provides protection for your user
account. A poorly chosen password equates to a weak frontline, and may result
in the theft of your user account. A stolen user account could then be
utilized to expose other network resources within the college. Therefore, all
ABAC faculty, students, and employees (including contractors and vendors with
access to ABAC systems) are responsible for ensuring their accounts are
protected by secure passwords.
Your unique name, or userID,
allows you to access the resources and services associated with the ABAC’s
network. Every time you connect, you are challenged for a string of
characters known as your password for validation purposes. If someone else
determines your password, they can effectively assume your electronic
identity. This means that individual then has full access to your files, your
e-mail, personal information, and more. This intruder could modify or destroy
your files, send threats via e-mail in your name, or subscribe to unwanted
services for which you'd have to pay. In short, an insecure password can
easily wreak havoc in your life.
- Strong passwords are
required for all accounts and should be 8 characters long, a mixture of
upper and lower case letters, punctuation and numeric characters.
- Passwords should be
changed every 3-6 months.
- Passwords should
remain confidential and original.
How to Remember Complex Passwords
It is possible to construct a password that is acceptable
and memorable. The following are provided as examples only and should not be
used; create your own password unique and memorable to yourself.
- Creating a "pass
phrase" is one way that helps to memorize a complex password. An
example of a valid and secure pass phrase might be "Tqbf^0t1D"
which is based on the old typing practice sentence "The Quick Brown
Fox Jumped Over the Lazy Dog!"
Substituting numeric or special characters adds to the complexity of the
password making it much more difficult to crack.
- Use lines from a
childhood verse:
Verse Line: Yankee Doodle went to town
Password: Ydw2~twn
- Foods disliked during
childhood:
Food: rice and raisin pudding
Password: r1c&ra1P
- My license plate is
"880-PTW". That's not acceptable; hackers know that people
will use their license plate as a password so it's very easy to scan for
passwords which are license plates. So, let's mix it up a bit -
"88oh-PtW" is acceptable and is such a minor variation that I
ought to be able to remember it.
- Passwords should never
be a word found in a dictionary (even foreign). Instead, use two or more
words joined together. Or, use a combination of words and numbers. For
example, instead of "dog and cat", use d0g+C4t! In this
example, we have used upper and lowercase, numeric, and special
characters thus creating a very secure and easy to remember password.
Password Caveats (Should Not)
- Passwords should not
be shared or written down. Treat your password like Kleenex, once shared
with a friend don't use it again.
- Passwords should not
be a word found in a dictionary (even foreign).
- Passwords should not contain
any form of your name or userid. Don't use
obvious passwords like "password", "guest",
"user", or "admin".
- Don't use personal
information, such as names of family members or pets, your date of
birth, social security number, or other similar information as part of a
password. Since such information may be public, you should not use it in
a password, even in combination with other characters.
- Don't use common words
or acronyms; spelled forwards or backwards.
Protecting Yourself Against
Password Loss
- DO NOT record your
password on a post-it note stuck to your monitor or slid under your
keyboard.
- If you have a secure
location, such as a safe or a safety deposit box, you may want to store
a written copy of your passwords there. Do not record your userID in the same location.
- Log off your computer
at the end of the day.
- Avoid using
password-saving features, such as Microsoft's Auto Complete feature.
- Use a
password-protected screen saver if you leave your computer, even for a
few minutes.
- If you think your
password has been compromised, change it immediately.
- Remind everyone in
your work area or office to change his or her passwords if someone in
the group is suddenly put on disciplinary leave, or is fired.
Writing down your password
There is a rule of thumb in the security community that
one should never write down a password. Writing down a password
increases the risk of it falling into the wrong hands. However, the policy we
enforce is such that it is often difficult to remember a password. The requirement
for remembering more than one password further complicates the situation. If
this is the case, then you could record them, but make sure that they are
stored in a secure place - white boards, sticky notes on your monitor, and
under your keyboard are not considered secure. Passwords should never be
recorded with your userID as you would never record
your pin number on your bankcard.
