What is computer network security?
Computer security is the process of
preventing and detecting unauthorized use of your computer.
Prevention measures help you to stop unauthorized users
(also known as "intruders") from accessing any part of your
computer system. Detection helps you to determine whether or
not someone attempted to break into your system, if they
were successful, and what they may have done.
Why should I care about computer
security?
We use computers for everything from
banking and investing to shopping and communicating with
others through email or chat programs. Although you
may not consider your communications "top secret," you
probably do not want strangers reading your email, using
your computer to attack other systems, sending forged email
from your computer, or examining personal information stored
on your computer (such as financial statements).
Who would want to break into my
computer at home?
Intruders (also referred to as hackers,
attackers, or crackers) may not care about your identity.
Often they want to gain control of your computer so they can
use it to launch attacks on other computer systems.
Having control of your computer gives
them the ability to hide their true location as they launch
attacks, often against high-profile computer systems such as
government or financial systems. Even if you have a computer
connected to the Internet only to play the latest games or
to send email to friends and family, your computer may be a
target.
Intruders may be able to watch all your
actions on the computer, or cause damage to your computer by
reformatting your hard drive or changing your data.
How easy is it to break into my
computer?
Unfortunately, intruders are always
discovering new vulnerabilities (informally called "holes")
to exploit in computer software. The complexity of software
makes it increasingly difficult to thoroughly test the
security of computer systems.
When holes are discovered, computer
vendors will usually develop patches to address the
problem(s). However, it is up to you, the user, to obtain
and install the patches, or correctly configure the software
to operate more securely. Most of the incident reports of
computer break-ins received at Piller Development could have been
prevented if system administrators and users kept their
computers up-to-date with patches and security fixes.
Also, some software applications have
default settings that allow other users to access your
computer unless you change the settings to be more secure.
Examples include chat programs that let outsiders execute
commands on your computer or web browsers that could allow
someone to place harmful programs on your computer that run
when you click on them.
Most of us at home have a wireless network. This is the
easiest way for a hacker to gain access to your computer.
Proper wireless network security is essential to keeping
your data secure.
What can I do to prevent hackers from gaining access
to my computer through my wireless network?
Manufacturers of wireless routers make setting up a
wireless network very simple. For the most part its just a
matter of plugging in the router and connecting a data
source. Most users think that since they have internet
connectivity they are done. This is what the hacker relies
on. Piller development specializes in home wireless
security. We can make your system secure, keeping your
passwords and files out of the hackers hands, giving you
peace of mind. To learn more see our
