What is network security?

Network security is the process of preventing and detecting the unauthorized use of your computer. Prevention measures help you to stop unauthorized users (also known as "network intruders") from accessing any part of your computer system. Detection helps you to determine whether or not someone has attempted to break into your system, whether they were successful, and what they may have done.

Network security gives you peace of mind about the security of your computer systems and internet connections. This involves making contingency plans for what to do when attackers strike, keeping up with the latest CERT advisories, and hiring network security consultants to find any vulnerable elements in your network.

Making sure your network is secure also means that you as the owner of the information and computer system must be able to access it, to enter information and look up details without the network security jamming and denying you access to your own information. Cyber criminals can even gain control of your computer, allowing them to hide their true location as they launch attacks, often against high-profile computer systems such as government or financial systems.

Although you may not believe that the information on your computer is "top secret," you probably do not want strangers reading your emails, using your computer to attack other systems, sending forged emails from your computer, or examining personal information stored on your computer, such as bank statements.

What does network security have to do with my home or office?

Many people believe that their home or office internet connection is not important and that their firewall and anti-virus software will protect them. Alas, this is not the case.

Take, for instance, your WiFi connection. You have set it up, entered your password and believe that you are safe. However, a cyber thief can hack your password and gain access to your network. This is called piggybacking and squatting and amounts to more than simple network theft. When wireless squatters steal your WiFi, they eat up your bandwidth. In some extraordinary cases, they may even steal information off your computer or infect machines on your network with a virus.

Unless you are familiar with these dangers and how to prevent them, you simply dont know when your personal information will be compromised. Having wireless network security procedures in place has thus become an important aspect of everyones internet experience.
