Computer Security
by Jo Escotal on March 14th, 2010What is computer security?
Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help you to stop unauthorized users from accessing any part of your computer. By being proactive you can find out who is trying to break in to your computer system.
Why should I care?
We use computers for everything from online banking, credit card transactions and communicating with others through email or social networking sites such as Facebook and Twitter. Although you may not consider your information to be "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?
Hackers, Crackers and People who have nothing better to do with their time than to cause havoc. Often they want to gain control of your computer so they can use it to launch attacks on other computer systems.
How easy is it to break into my computer?
Very easy many crackers find holes and vulnerabilities to exploit your computer.
