Protecting Your Home Wi-Fi Network
When setting up a home Wi-Fi (or wireless network), most people just rush through setting up a router to get Internet connectivity. However, numerous security problems can result from not securing your wireless router.
How do you secure a wireless router?
It is crucial to change the router’s default password, router login ID and password. The default login credentials are simple and very well-known to hackers. Change these settings immediately.
Use WPA2/PSK encryption instead of WEP.
Change the default SSID (Network Name) immediately when configuring wireless security on your network. Manufacturers normally ship their products with the same default SSID. When someone notices a default SSID being used, they see it as a poorly configured network and are much more likely to attack it.
Disable SSID Broadcast. In Wi-Fi networking, the wireless router usually broadcasts the network name over the air. At home, this feature is unnecessary, and increases the likelihood that someone will try to log into your home Wi-Fi network.
Enable MAC Filtering. Each piece of Wi-Fi equipment possesses a unique identifier called the physical address or MAC address. Many routers offer the option to key in the MAC addresses of your devices, which restricts the network to only allow connections from those devices.
Place the router in a safe location. Wi-Fi signals often reach through neighbouring homes and into streets. The position of the router determines its reach. When installing your wireless home network, try to position your router near the centre of the home rather than near windows.
