UNDER CONSTRUCTION COME AGAIN
Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help you to stop unauthorized users ("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.
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).
Intruders (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, your computer become a zombie.
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 .
How easy is it to break into my computer?
Unfortunately, intruders are always discovering new vulnerabilities or holes to exploit in computer software. The complexity of software makes it increasingly difficult to thoroughly test the security of computer systems.
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.
