Securing your wireless network

Using radio waves, a wireless network introduces some security risks which are not present in a wired network; an unauthorized third party can intercept trans- mitted data, gain access to your wireless network, … In order to make your wireless network as secure as a wired network you should apply, at least, the following guidelines:

1.Change the SSID

Your wireless network is identified on the basis of an SSID (Service Set Identifier). This parmeter, which can be considered as the networkname, is broadcasted periodically through a beacon. Also the SSID is, in most cases, set default to a welknown value. To improve the security you can :

1.disable the SSID broadcast. Users who want to connect to your wireless network must know this value to become connected. Also, your wireless network becomes invisible to a third party.

2.change the default value of the SSID. The SSID can contain maximal 32 characters and it’s best to choose a value which is not too obvious.

2Activate WEP

To guarantee that your data is transmitted in a private manner, you should activate WEP (Wired Equivalent Privacy). Use of this protocol will result in your data being encrypted while travelling through the air. Choose the largest encryption key possible (in most cases this is 128 bits) and make sure that each PC on your wireless network uses the same key as the access point. You can even improve the security by changing the WEP-key on a regular base.

3Activate MAC-address control list

By means of the MAC-address list, also known as the Association Control List, you can determine which client adapters can access your wireless network. This is done by introducing the MAC-address of the client adapter in the concerned list of the access point. A MAC address consists of 12 characters (0-9,A-F) and can be found on the back of the client adapter. A client adapter whose MAC address is not included in the list will not be granted access to your wireless network.

4Change / activate passwords

Configuration of the access point is done through a web browser. Secure this access, and any other access which may exist, by a carefully chosen pass- word. If a default password, set by the manufacturer, is used, you should replace this by your own password.

1.I’m not sure what information I need from my Internet Service Provider (ISP) to get my network up and running. What questions should I ask?

What type of connection do I have: dynamic IP address, static IP address, or PPPoE?

•If I am using a dynamic IP address, I should ask:

-What is my Host Name (if needed)?

-What is my Domain Name (if needed)?

•If I am using a static IP address, I should ask:

-What is my IP Address?

-What is my Gateway?

-What is my DNS?

•If I am using PPPoE (typically used by ADSL ISPs), I should ask:

-What is my User Name?

-What is my Password?

After you obtain the information, follow the instructions in the Fast Start - Step
