Computing the Activity of Connecting Computers in Network Security

Network 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 network 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 network to attack other systems, sending forged email from your computer, or examining personal information stored on your network.
