How Strong Are Your Passwords?
by Mike Gonsalves,

Most
people don't realize that computer security starts with
them. An easy way to hold off trouble is to use strong
passwords that you change every so often.
What is a
strong Password? It is a password that is easily
remembered by you, contains uppercase letters, lower
case letters, a number or two, a special character and
is at least 8 characters in length.
Sounds
hard, but it's really easy when you use things you are
familiar with.
For
example, if I grew up at 245 Lucky Street, I might make
my password Lucky245& Notice I've used Uppercase and
Lowercase Letters, I have 3 numbers and a special
character.
Here are
some variations on the above password luCky24%,
LuckY245$, luckY245* You can come up with a bunch if you
just think about it a little bit.
Another
example might be something you like, like Ice Cream, you
could change it to 1cecr3@M Notice that I changed the
first I in ice Cream to the numeral 1. The second e is
represented by the number 3, sort of an E in reverse.
The "a" became an @ sign.
Why go
to all this bother?
It's almost impossible to break strong passwords.
Passwords that are easy to break are common words or
names (like Mike, Jump, Secret, Car, Emily, or, my
favorite, and yours, Password).
Don't
think for a minute that someone is actually sitting
somewhere on the globe thinking about your password,
they've automated all that. They start a software
program that goes after known vulnerabilities, or
specific targets that contain a lot of valuable data,
like Credit Cards, Personal Identification, such as
Social Security numbers, date of birth, etc. The
software does the work for them.
Why do we
need passwords at all? Simply put, it is a matter of
Authentication. Are you who you say you are, or are you
someone who is pretending to be someone else? When a you
are pulled over by a police officer for speeding, the
first thing he asks you for is . License and
Registration. The License authenticates who you are via
the photo, signature, basic information about you like
eye color, date of birth, height, weight, address, etc.
The
registration authenticates ownership of the vehicle.
(Passports are a very good form of Authentication as
well) The bottom line is this, if you don't want someone
else looking at your data, use strong passwords to
protect it. Here's a good article on the Microsoft
