Wireless networks are becoming order the day very fast. The ability to connect to the Internet from anywhere while moving is quite appealing. But with this ease comes the issue of security since hackers find it quite easy to penetrate a wireless network. Once your network is penetrated, you will lose your important data and even you may have to face the trouble of identity theft. So it becomes more than necessary to put some restriction measures into the place to ensure the security of your wireless network.
Follow these simple guidelines to restrict the access to your wireless network by an intruder.
Step 1: Any new Internet product comes with a default administrator password so that you can set up the process easily. Anybody can track these default passwords online and accessing you system will be a child’s play for an attacker. So change the default passwords as soon as start setting up your system.
Step 2: Make your SSID hidden by disabling it in the SSID broadcast box. This way your router will not be broadcasted to any possible intruders. There will less chances of penetration to your network if it looks like it do not exist! To do this, go to your Wi-Fi router’s settings page, and look for the wireless settings. You can hide your SSID broadcast from here. When you need to connect a client, you’ll need to type the SSID manually. This is a little troublesome but since the network isn’t listed for you, it will not be easy for a casual eavesdroppers to find it either. Still, you have to be cautious since it is easy to find hidden networks with a few more steps. You may say that only stop casual bandwidth opportunists will be stopped by this step.
Step 3: You can also change your Wireless Network name to something different and reveal it to only those whomever you authorize to use it. You can do this by logging on to your administrator screen. Here clicking on the wireless link will open up a box. In it change your Wireless Network name to something different.
Step 4: You do not require a password if you wish to keep your network open. But considering the security threat it can pose to your network, I would suggest that you set up a password for your network and also encrypt your data before sending it on the network. There are various encryption methods are available. Choose WPA since it provides better protection.WPA2 is also ideal for most simple networks.
Step 5: Another thing you can do to restrict your network is to filter by MAC address. This way only known wireless clients can be allowed into your network by looking into a table of unique MAC addresses. While anybody can acquire a fake MAC addresses, generally the factory assign a single ID to network-connected hardware. Let the wireless client connect to the router and visit the router’s list of clients. The MAC address of the client should be listed there. Copy the address to MAC filter list configuration page. Then activate filtering, and only devices with those known MAC addresses can connect.
