How safe is your
computer? It takes only minutes before an unprotected
computer on the internet becomes infected.
Twenty minutes. That's how quickly an unprotected computer can
become infected on the internet, according to research institute
Sans.org.
Ryan Purita, a consultant with Totally Connected
Security Ltd., wanted to see this for himself. He hooked up a PC
with default settings to the internet: It had no anti-virus
software, no firewall, and no operating system patches. In about
ONE MINUTE, says Purita, it was hacked, infected, and it had started
propagating virus infections to other computers.
TIRED AND
FRUSTRATED of their virus and spyware plagued PC, Rosslyn Berot-Burns
and her husband Paul are seriously contemplating logging off
permanently. Their three kids protest, but each week brings
more virus infections, and more time and money thrown at their
problem machine. The past year has seen their system go through
multiple crashes, a multitude of pop-ups, and their browser doing
unexpected things. Even with an anti-virus program and a firewall,
the computer's still getting infected, says Rosslyn.
Calling
herself an average home user, Rosslyn says she doesn't understand
how a lot of the programs work. What it comes down to, says Rosslyn,
is that the home users have to make it their responsibility to find
out how to protect their machines.
"If you really want to have the computer, first of all find
out what you need in order to protect your PC. Or don't use it.
That's where I'm at right now."
"Home users still lack the most fundamental education regarding
security. When people enter in their PIN number at an ATM and people
are around, they are aware and take steps to prevent disclosure of
sensitive information. However, some of the same people will
willingly fill-out their real name, address, phone number and even
credit card information from an unsolicited email, or banner pop
up," says Purita.
Some home users are so frustrated and
confused by the pitfalls of the internet, they have decided to do
the one thing they know will protect them: log off permanently. The
process of security is just too time-consuming and intimidating for
them. Producer/writer: Ruby Buiza | Writer/researcher: Laura

Don't think you need
protection from viruses and spyware? First of all,
what do I need protection from? And what will happen if I
choose not to protect my PC? Letís define the enemy:
Computer Vandalism -
Hackers may perform mischievous activities such as deleting files up
to and including reformatting your hard drive(s).
Malware -
Short for malicious
software, software designed specifically to damage or
disrupt a system, such as a virus or a Trojan horse.
Trojan Horse Program -
A
destructive program that masquerades as a benign application. Unlike
viruses, Trojan horses do not replicate themselves but they can be
just as destructive. One of the most insidious types of Trojan horse
is a program that claims to rid your computer of viruses but instead
introduces viruses onto your computer. The term comes from the a
Greek story of the Trojan War, in which the Greeks give a giant
wooden horse to their foes, the Trojans, ostensibly as a peace
offering. But after the Trojans drag the horse inside their city
walls, Greek soldiers sneak out of the horse's hollow belly and open
the city gates, allowing their compatriots to pour in and capture
Troy.
SpyWare - Any software that covertly
gathers user information through the user's Internet connection
without his or her knowledge, usually for advertising purposes.
Spyware applications are typically bundled as a hidden component of
freeware or shareware programs that can be downloaded from the
Internet; however, it should be noted that the majority of shareware
and freeware applications do not come with spyware. Once installed,
the spyware monitors user activity on the Internet and transmits
that information in the background to someone else. Spyware can also
gather information about e-mail addresses and even passwords and
credit card numbers.
Spyware is similar to a Trojan horse in that users unwittingly
install the product when they install something else. A common way
to become a victim of spyware is to download certain peer-to-peer
file swapping products that are available today. Aside from
the questions of ethics and privacy, spyware steals from the user by
using the computer's memory resources and also by eating bandwidth
as it sends information back to the spyware's home base via the
user's Internet connection. Because spyware is using memory and
system resources, the applications running in the background can
lead to system crashes or general system instability. Because
spyware exists as independent executable programs, they have the
ability to monitor keystrokes, scan files on the hard drive, snoop
other applications, such as chat programs or word processors,
install other spyware programs, read cookies, change the default
home page on the Web browser, consistently relaying this information
back to the spyware author who will either use it for
advertising/marketing purposes or sell the information to another
party. Licensing agreements that accompany software downloads
sometimes warn the user that a spyware program will be installed
along with the requested software, but the licensing agreements may
not always be read completely because the notice of a spyware
installation is often couched in obtuse, hard-to-read legal
disclaimers.
Virus -
A program or piece of code that is
loaded onto your computer without your knowledge and runs against
your wishes. Viruses can also replicate themselves. All computer
viruses are manmade. A simple virus that can make a copy of itself
over and over again is relatively easy to produce. Even such a
simple virus is dangerous because it will quickly use all available
memory and bring the system to a halt. An even more dangerous type
of virus is one capable of transmitting itself across networks and
bypassing security systems.
Worm -
A program or algorithm that
replicates itself over a computer network and usually performs
malicious actions, such as using up the computer's resources and
possibly shutting the system down.
According to CERT/CC, a
growing risk to Internet users without dedicated IT support are at
risk of exploitation in increasingly shorter periods of time. This
problem is exacerbated by a number of issues, including:
- Many computers'
default configurations are insecure.
- New security
vulnerabilities may have been discovered between the time the
computer was built and configured by the manufacturer and the
user setting up the computer for the first time.
- When upgrading
software from commercially packaged media (e.g., CD-ROM,
DVD-ROM), new vulnerabilities may have been discovered since the
disc was manufactured.
- Attackers know the
common broadband and dial-up IP address ranges, and scan them
regularly.
- Numerous worms are
already circulating on the Internet continuously scanning for
new computers to exploit.
As a result, the
average time-to-exploitation on some networks for an unprotected
computer is measured in minutes. This is especially true in the
address ranges used by cable modem, DSL, and dial-up providers.
Standard advice
to home users has been to download and install software patches as
soon as possible after connecting a new computer to the Internet.
However, since the background intruder scanning activity is
pervasive, it may not be possible for the user to complete the
download and installation of software patches before the
vulnerabilities they are trying to fix are exploited.
