answer:The security of your connection to the internet is a two way street: your computer is happy to encrypt the data you send over the internet, but the server receiving the data needs to be happy to receive it. Most good websites do this automatically; and you’ll see a padlock in your address bar, or status bar, when this is happening. However, you are more than likely talking about a wireless network. In which case, you’ll want to take a few steps to secure it. 1. Turn off SSID broadcasting. This stops your router from telling all and sundry about itself. 2. Turn on WPA. If your router supports this security setting, then use it over WEP. 3. (optional, really) Turn on MAC address filtering. This means that your router will only let certain devices (which you have to specify) connect to it. Hope that helps :-]
