Network Security

While the Internet gives you access to a large quantity of information and business opportunity, it also opens your network to attackers. A good network security policy helps you find and prevent attacks to your computer or network. Many people think that their computer holds no important information. They do not think that their computer is a target for a hacker. This is not correct. A hacker can use your computer as a platform to attack other computers or networks or use your account information to send e-mail spam or attacks. Your account information is also vulnerable and valuable to hackers.

About Networks

A network is a group of computers and other devices that are connected to each other. It can be two computers that you connect with a serial cable, or many computers around the world connected through the Internet. Computers on the same network can do work together and share data. A LAN (Local Area Network) is a connected group of computers that use the same method of communication to share data. A WAN (Wide Area Network) is a connected group of computers that can be far apart in different locations.
