    Computer Networks & You

    What exactly is a computer network? In essence, it's group of two or more computers that are connected together in some way, usually by the Internet or by an internal connection. Having a network between groups of computers make it easier for people to share and retrieve documents from other people or businesses and even each other.

    While computer networking was of vital importance within businesses and corporations, once the personal computer found its way into Learn About Network Security Issues the homes of individuals, networking began to encompass both business and personal use. And why not? Most homes will have at a minimum of two computers in the house, whether they be laptop computers or desktop computers.

    There are two types of networks - that of wired networks and wireless networks. Wireless is probably the most popular due to the surge in popularity of laptops, but many times these networks are unsecured. Unsecured networks are those networks that are not password protected, meaning anyone that comes into the radius of your wireless signal, they can use your Internet connection. Not only that, but they will also have access to your files and documents as they are now a part of your network.

This can lead to a variety of problems, such as becoming a victim of phishing scams or identity theft.

This is usually done upon the initial set up of your wireless network, when you are able to log in to your router in order to set up your network. You should always start by setting a password to both your router and that of your network. There are several encryption types, but the most popular are WEP & WPA.

    • WEP - this is the older encryption and by the far the weakest, as it has been known to allow intrusions that are not authorized.
    • WPA - the newer standard that came to replace WEP. The finished product is WPA2. This has a greater overall security.

    MAC Filter - a MAC filter is when only the computers you authorize are allowed on your network, basically telling your network that only these addresses are allowed access. Anyone not on the list doesn't get in.
