Computer Security - It's Bigger Than Spyware And Viruses
Computer security, in basic terms means keeping your computer
and the data that's in it safe and secure. More of our personal
data is stored in or accessed from our computer, now more than
ever before. Yet most people lack even the basic understanding
of how to keep their computers safe and secure. By following
just a few simple rules you can dramatically improve the overall
security of your computer.
The first thing to understand is what exactly it means to be
connected to the internet. Your computer connected to the
internet is similar to your house in many ways. There are many
ways into your house. Windows, doors, etc. The more windows and
doors you have, the more ways someone has into your house. An
open door doesn't necessarily mean you are going to be robbed,
but it does improve the chances. Complicating matters, the ones
that you think are locked, may not be because the lock is faulty
or even the door itself may have an as of yet undiscovered flaw
that would allow an intruder easy access to your home.
Your computer has many windows and doors, not all of which are
locked. New flaws are being found everyday, often with the fix
not coming until days after. Just like you wouldn't leave your
front door unlocked, you shouldn't leave your computer wide open
either. The first two things we will discuss to help with this
task are installation of a quality firewall and regularly
updating your installed software.
Updating your software is becoming easier these days, especially
your Operating System. We don't have the time here to go into
detail about the many ways to update the many software packages
you may have or use, but generally speaking the software
manufacturer will provide you a way to do this automatically via
the internet. A good example of this is the Microsoft Windows
Update feature. Be sure to get the updates for everything
installed on your computer, nothing is too trivial.
There are two basic types of firewalls and both perform the same
functions. One is hardware the other is software. A hardware
firewall is probably included in your router if you are using
one, while you may or may not have a software firewall
installed. To continue our house analogy, a firewall is like
building a wall and gate around your home and giving the guard
at the gate instructions on who to let in and out. While this
does give a great deal of protection, it is not all that is
required. Someone may know a way around or under your wall, or
even be able to coerce the guard into letting them in.
You yourself may unwittingly allow someone in. This could happen
by simply opening an email or even simply surfing the net.
Spyware, viruses, trojans and the like are ever more adept in
their methods of fooling you and your guards. Emails may come
from a trusted friend containing a dangerous virus without them
even knowing it. This is where the next layer of protection
comes in, anti-virus software.
Anti-virus software is a large category these days. Often these
packages come as "suites" including a firewall and Spyware
scanner. While most of these programs are very effective in
their promised tasks, it is not wise to be lulled into a false
sense of security by them. They are simply one layer in what
should be a multi tiered protection plan for you and your
computer. One last important note about anti virus software is
to be sure that it updates on a regular basis. New threats come
out daily so check its updates manually to be sure they have
happened.
Back to our house analogy, we now have all of our windows, doors
and other entry ways locked and fully updated. We have a wall
around our house with a guard at the gate and we have software
scanning everything that comes in past the gate. Sounds pretty
good, but there's one last security hole we need to address, you.
A large percentage of infections are caused by the computer user
themselves. The internet is an ever changing place that requires
it's users to be educated about its use. I'm not suggesting that
you need to be a computer expert to simply read your email. I am
however suggesting that you take some time to educate yourself
on some of the dangers that pop up everyday, and the precautions
to take in order to avoid them.
In summary, your computer is a powerful machine connected to one
of the greatest things ever invented, the internet. This vast
resource can be a dangerous place if you are not properly
prepared and informed. Regular software updates, a good
firewall, anti virus software and a little education are the
basics in computer security. Having and understanding these
basics will make your computer safer, more secure and more
enjoyable.
