Secure WiFi  - How Does it Work?

If your wireless router is left over from the turn of the century, you owe it to yourself to upgrade to something that is in step with the times. Depending on your Internet connection, increasing your bandwidth is a tricky and the easiest way to do it is by upgrading your wireless router. These next-gen routers are simple to use and don’t require passwords; something that increases network security and ease of use.

Wi-Fi Passwords Are Overrated
The most common method of connecting a device to a wireless network is by entering that network’s password. Hackers take advantage of this by developing sophisticated methods and technologies to decipher the handful of characters standing between them and your personal information. Using Graphic Processing Units (GPUs) and brute force attack methods, a hacker can rapidly input up to 8.2 billion password combinations per second. This approach gives them a good chance at getting your vital information.

Tap-to-Connect                   
Let’s face it; Wi-Fi passwords are not as secure as they used to be. Fortunately tech developers are coming up with better ways to secure your network. Tap-to-connect routers are examples of this new technology. These routers have a button that can instantaneously connect a user to their Wi-Fi network. The button triggers a signal that is then sent to your wireless device. All you need to do is authenticate the device and it is ready to use. The advantage that these routers have is that a hacker can’t access your network unless he breaks into the building and presses the button himself.

With tap-to-connect, connecting to the Internet is made far more convenient. All you need to do is push the button on the router, and ta-da; you’re connected to the network. This allows visitors to your company to share your signal.

Near Field Communication (NFC)
If pushing a button is still too much, you can use NFC to connect your device to your Wi-Fi network. A router equipped with Near Field Communication technology will detect your device when it is nearby, and voila – your device is automatically connected and logged on to the Internet. ZDNet explains how this works:

Through the new NFC-enabled method, the router’s configuration is wirelessly handed to the device and will be connected via WPA2 security, either through a traditional wireless network or an ad-hoc direct network.

More than 10,000 wireless devices have been certified for Wi-Fi protected setup since 2007, and a significant number of them are utilizing NFC technology.

PIN Entry
A unique PIN is assigned to each device that joins a protected Wi-Fi network, and is required in order to access the network. These PINs are used to ensure that the device trying to connect to the network is allowed to do so. This helps to avoid “accidental”, or rather, malicious, attempts to access the system.

So, what’s the difference between a PIN and a password? The PIN is assigned by a registrar device (in this case, the wireless router), and it will detect when a new device is in range. The device will then prompt a PIN entry. The PIN is encrypted by the system making it far more secure than a password.

Li-Fi – Wi-Fi Connection at the Speed of Light
That’s right – the broadcasting of the Internet via light energy has been successfully tested and is currently in development! Li-Fi has the potential to send digital information over a light spectrum at 10 gigabytes per second. To put it in perspective, that’s 250 times faster than the average broadband connection, and might be the most secure method of using a wireless network. Wi-Fi, which uses radio waves that pass through solid objects and walls, is significantly less secure than Li-Fi, which is limited to the room illuminated by the Li-Fi bulb. So, a hacker would have to break into your house and turn on your lights in order to access your network. Unless you sleep like a log, you’ll be sure to catch them in the act.

Your company probably uses several different access points like Wi-Fi, and probably uses a variety of network-connected devices. Each access point creates new security obstacles to overcome. You should never neglect the security of Wi-Fi in favor of your local Internet connection. Quikteks can help you make sure that your network access points are secure. Give us a call at (973) 882-4644!
