Protecting
Your PC for the Holidays
Safeguarding your data is always of critical importance,
but could be even more important the approaching
holidays. With more people staying at home during
their vacations, bored hackers may decide to target
and corrupt your important data, try to take control
of your PC, or other wicked and nefarious deeds.
Combine bored hackers with the glut of Always-on,
high-speed connections and you are looking at
a potentially devastating kid in a candy store.
I've never had any hacker problems before."
You say, "Why should I think it's a real
problem for me today? I mean, they only hit the
big sites, right?
The truth is: If you have never had security
software before, or even just for the last few
days, someone could have a back door into your
PC right now! We are not trying to promote fear,
but you should be aware of and protected from
any unauthorized access to your computer.
So, what kinds of things can a malicious
attacker do over the internet to your PC?
Destroy - Delete data off your computer
Vandalize - Change data on your computer to something
else (note occurrences where publication sites
have had phony articles put on their site)
Spy - Install a backdoor to watch your every keystroke,
what programs you use, when you use it, and even
what sites you visit
Control - Take control of your PC to perform illegal
activities, such as hosting child pornography,
or participating in broad based internet attacks
including DoS (Denial Of Service) attacks or sending
Spam mail through your computer.
Deny - Some attacks use up all your internet bandwidth,
or crash your computer, denying your ability to
use the internet, or even your own PC.
Why would someone do this?
Power, boredom, money, or any number of other
reasons. The truth of the matter is that most
malicious attacks are not made by internet experts.
They are made by young kids or inexperienced adults,
who know something about the internet, but have
found programs to allow them to perform these
attacks. They risk exposure to viruses, backdoors,
and more to have this power, yet they do it anyway,
because they don't have the investment you have
in using the PC for productive gains. It becomes
a game for many of these people.
How can I protect myself from these people?
Your best method of defense would be to disconnect
your computer from the internet and never install
anything from an unknown source on it. Well, that
just isn't going to work for the vast majority
of people. That brings us to the need for something
that will prevent these people from accessing
your computer and, if access is gained, prevent
them from getting back out. That something is
called a firewall.
What exactly is a firewall, and how do
I use it?
Well, a firewall is a layer between you and danger.
In internet terms, this is either hardware (physical
components installed into your computer), or software
(programs) that works as a gatekeeper for all
of your internet traffic. Your firewall passes
the traffic it sees as "safe" into or
out of your PC. A good firewall can block not
only incoming, but outgoing requests, but not
all will.
I can see the reasons for blocking the
hackers from getting in, but why would I want
to block outgoing requests?
Let's say for example, you get an email asking
you to download some application, that is supposed
to just show some fireworks, or is a solitaire
card game. You wouldn't expect this program to
connect to the internet would you? Yet, if this
program contains malicious spyware, or a backdoor,
it may report your PC's presence to the author,
and announce that it is now running on your PC.
If you could block outgoing connections, you have
an opportunity to stop this announcement, as well
as know what this program tried to do. These guys
can get tricky.
Ok, I need protection. What's better,
a hardware, or software firewall?
For best protection, you should have both. In
a car, people commonly buy a security device (such
as a steering wheel or pedal bar-lock), even though
they have a lock on their door. They do this because
if one layer of security is breeched, another
one is there to stop them. Even if you have a
hardware firewall, you should get a software firewall.
Let's take a look at some of the common benefits
of a hardware firewall:
- Can often protect multiple computers easily.
- Can often provide internet access for multiple
computers through a single connection (this
is called a proxy server).
- Typically can function on any Operating System.
i.e. Linux, Windows, OS2...
And then some of the common benefits of a software
firewall:
- It will be running whenever the computer is
on, even if the computer is portable, and moved
(like a laptop between home and the office).
- Can provide protection against programs connecting
out from your computer.
- Can be configured to allow selected programs
to access the internet while blocking others.
So, it should be clear that you need protection.
However you plan to get it, do it now. We have
reviewed a number of software firewalls and found
Privatefirewall 3 to be the best. That is why
it is now available through our website.
