WiFi networks have improved tremendously over the years, with new and convenient ways to keep your network efficient and secure.  In the past, Wired Equivalent Privacy (WEP) was considered the standard in keeping your network secure. But today, WEP is very easy to crack thanks to the new tools that hackers have at their disposal. 

Today someone may say “Here’s our WiFi password” and hand you a note with the combination of letters and numbers needed to access their network.  While there are a few different standards to protect a WiFi network, the main premise of this model is having a single string of characters anyone can use to access the network. These passwords are often simple, making it painless for an attacker to break in and gain access.   

Other times, the network password may contain 20+ characters with various special characters scattered throughout.  While the latter may be more secure, it poses another challenge.  What happens when that complex password is compromised?  If you work in a multi-site organization with many devices, it can be extremely difficult and time consuming to change the WiFi password and reconnect each device.   

What if there was a more secure and efficient approach?  

One solution to wireless security is using a RADIUS-authenticated network.  In some respects, it can introduce additional complexity on the back end and take more effort to implement. But when one password or device is compromised, you would no longer need to go through the tedious and time-consuming process of changing a password and reconnecting all devices.  What if there were no passwords?  What if most computers in your organization never required a person to type in a username and password combination in the first place?  This is all possible with a RADIUS-authenticated network.  

There are several solutions available, including Microsoft’s Network Policy Server.  In fact, this is natively incorporated in the Windows Server operating system.  There are many Network Admissions Control (NAC) solutions available that offer the same service as well, whether on-premise or cloud hosted. 

If you haven’t explored RADIUS-based WiFi solutions for your organization, give us a call and we would be happy to talk you through it!
