What is Wireless Network Security ? Explained with Examples

By | 9th November 2015

Use the following recommendations for additional security on your wireless networks.

Use a network security key

If you have a home or office wireless network, you should set up a network security key, which turns on encryption. With this, other people (except authorise users) can’t connect to your network without the security key. Also, any information that is sent across your network is encrypted so that only computers that have the key to decrypt the information can read it. This can help avert attempts to access your network and files without your permission.Known Wireless network encryptions are:

Wired Equivalent Privacy (WEP)

Wi-Fi Protected Access (WPA)

WPA-2.

Change the administrator name and password

If you have a router or access point, you probably used a default name and password to set up the device. Most manufacturers use the same default name and password for all of their equipment, this enables anyone to gain access your router or access point without you knowing it. To secure your network, change the default administrator user name and password for your router. Check the information that came with your device for instructions about how to change the name and password.

Change the default SSID

Routers and access points use a wireless network name called a service set identifier (SSID). Most manufacturers use the same SSID for all of their routers and access points.  Changing the default SSID helps to keep your wireless network from overlapping with other wireless networks that might be using the default SSID. It makes it easier for you to identify which wireless network is yours, if there are wireless network(s) nearby, because the SSID is typically shown in the list of available networks. Check the information that came with your device for instructions about how to change the default SSID.




Position your router or access point

Wireless signals can transmit a few hundred feet, so the signal from your network could be broadcast outside of your home. You can help limit the area that your wireless signal reaches by positioning your router or access point close to the centre of your home rather than near an outside wall or window.

Use Standard or User account

The standard account can help protect your computer by preventing users from making changes that affect everyone who uses the computer. A very good recommendation is for you to create a standard account for each user.

When you are logged on to Windows with a standard account, you can do anything that you would do with an administrator account, but if you want to do something that affects other users of the computer, such as installing software or changing security settings, Windows might ask you to provide a password for an administrator account.
