Security

Now that the network has been created, if it's connected to the internet you are prone to many security risks especially if you have a wireless network.
I will be explaining the risks and how to solve them in order to secure your network.

- One of the security threats once a wireless network is created is that its set as unsecure as default. This basically means that anyone within range of the wireless network can connect to your network and use your internet connection. How can you avoid this happening?

  • Wired Equivalency Privacy (WEP)

WEP is the basic form of security you can apply to a wireless network. What does it do? You can apply a password to the network meaning anyone wanting to connect to the network they have to know the correct password. This automatically limits the internet usage to people with permission. The data sent is encrypted before encryption providing higher security than having nothing applied. However, it is said the WEP's security isn't as realiable as WPA & WP2, which is what Im going to be talking about next.

  • WiFi Protected Access (WPA/WPA2)
  • Media Access Control (MAC) address filtering

MAC address filtering is not so commonly used in comparison to WEP and WPA, however this type of security is different. Every computers ethernet and wireless cards have MAC addresses. This can be found by going to Command Prompt (Start -> Run -> cmd) and typing in ipconfig /all . When searching for the network it shows as unsecure, however only computers with a MAC address which are saved on the access list will connect to the network.
