SBN How Does RADIUS Improve WiFi Security?

You may wonder, how does RADIUS improve WiFi security? Let’s discuss your current WiFi password dissemination practices, to illustrate the problem and why a RADIUS solution will help

Is your WiFi password written on the conference room whiteboard? Or, are you using a shared passphrase that is emailed? Perhaps you have people coming and going from your organization, which forces you to constantly hand out the WiFi password on sticky notes or paper.

Sure, these practices are convenient, but they’re not at all secure. The problem with the aforementioned methods is that it makes it far too easy for an intruder to jump on to your WiFi network and put your organization at risk. So, how can you protect your network? Let’s take a look at RADIUS and why it is the industry standard when it comes to locking down WiFi access.

What is RADIUS?

At its most basic, RADIUS is an acronym for Remote Authentication Dial In User Service. The “Dial In” part of the name shows RADIUS’s age: it’s been around since 1991. Today, however, RADIUS is widely used to authenticate and authorize users to remote WiFi networks (and VPNs, network infrastructure gear, and more). This process is generally completed with the WPA2 enterprise protocol on wireless access points (WAPs) — i.e. the shared SSID and passphrase process detailed above. But, it isn’t just remote network access that IT organizations are looking to leverage RADIUS for. When RADIUS is applied to on-premises networks, the security of that network is also increased. 

For organizations looking to use RADIUS, there are a good number of options available including: FreeRADIUS, Microsoft® NPS, Cisco ISA, RADIUS-as-a-Service, and many others.

RADIUS pairs with directory services solutions like Microsoft Active Directory® (AD) or OpenLDAP™ to fortify security for wireless networks. But how? In order to access a wireless network secured by RADIUS, the user must provide their own unique, core set of credentials. 

Essentially, the credentials a user has for their work system are the same ones they will use to log (Read more...)
