With so many of us now using the
internet for all number of things including banking, or storage
of confidential data a number of our clients have asked our advice
on how to choose a secure as possible password. We decided to do
this tutorial slightly different as it doesn’t give a step
by step guide but will give points that we feel should be considered
when you are selecting a strategy for passwords after all it is
going to be your personal password .
First thing we ask them is “What is your
current password?” and guess what, yes you guessed it almost
every single one of them straight away tell our engineer their password.
Luckily we are honest people and wouldn’t log onto the nearest
computer and empty their bank accounts or take the companies confidential
data but that person has just learned a very valuable lesson in
password security. Therefore no matter how good or secure a password
you choose IF YOU TELL SOMEONE IT IS NO LONGER SECURE, this is called
social engineering, which is a common technique used by the bad
guys to find passwords. Research has shown that most employees share
there passwords 8-10 times a year can you be sure that the people
gaining these passwords wont look at things they shouldn’t
see.
Does your password fall into any of these categories
something relating to friends, family, memorable dates, pastime,
or pets? According to a survey by credit card firm Visa Europe,
well over three quarters of surfers choose passwords relating to
friends, family and memorable dates. Therefore anyone who knows
a little about you should be able to guess your password without
much difficuty. Try this out on your partner/best friend/etc ask
them to have a few guesses of what they think your password would
be (remember not to tell them if they chose correctly or not). If
they guess exactly or relatively closely you know it wouldn’t
take much for them or even worse people you don’t trust to
guess the correct password.
Have you changed the default password?? Many applications
come with default passwords eg Admin, Password, or even worse blank
passwords as default. It is estrimated that the word 'password'
itself still accounts for two per cent of the UK’s most common
password choice. Armed with this info wouldn’t you try the
obvious first if trying to guess a password , so don’t make
it easy for anyone to guess your.
How long is your password?? A two letter password,
for example, has only 676 possible combinations. A password with
eight letters offers more safety with 208,000,000 combinations.
Now you have realised that longer passwords are
more secure but unfortunately that not the end of the story.
Does your password contain a mixture of letters,
numbers and characters?? With the power of modern computers lots
of crackers simply use the brute-force method of finding out your
password therefore any words contained in a dictionary and or common
password lists are quickly and easily checked using a computer application
which are easily downloaded from the internet.
By now you should have noticed a common theme and decided that a
long password which contains letters,numbers and characters is a
good option for choosing a password but random character passwords
like “d5gs45><hEG;~g5343~@12R” although the best
they are not easy to remember so why not select something that easier
for you to remember along lines of “1@eeZi0Ne#2#P1ck:-)”.
Please don’t use the example password as it would be pretty
easy to guess using the methods I have described as it uses very
common password words and is mererly showing how you should mix
everything up with letters in lower and higher case, characters,
numbers, nice typos, and long in length but still meaningful and
easy for you to remember.
After selecting passwords there is still a few
other things to remember change them regularly and have different
passwords for different things. After all you don’t want someone
if the manage to somehow guess your password having access to your
account forever and you don’t want them having guessed the
password to have access to every account on every service you have
with one single password.
Our final note no mater how secure if someone
is determined enough they will eventually guess a password using
brute force whether that being in seconds, hours, days, months or
years is purely down to how effective you make your password but
why make life easy for them after all very few going to spend time
trying to crack your as secure as possible password when there is
easier pickings elsewhere.
