RADIUS Authentication with Microsoft Office 365

A common trend in modern IT is a market-wide shift to the cloud. For many organizations, that means leveraging a cloud computing platform like Microsoft Office 365® (O365). O365 is the cloud version of the Microsoft Office Suite. It provides various applications and resources that most people are very familiar with like Word, Excel, PowerPoint, and Outlook.

While cloud productivity platforms like O365 have dramatically increased productivity by enabling users to be more agile and adaptable to the rapid changes in IT, there are still significant issues with on-prem network connectivity and infrastructure. Securing WiFi networks and cloud-based identities has become an essential aspect of an organization’s overall security posture.

One of the best approaches to securing cloud resources is by managing access to the network itself with the Remote Authentication Dial-In User Service (RADIUS). RADIUS allows organizations to require unique login credentials for each user on the network – eliminating the dangers of a shared WiFi password. However, the last thing that users want is another set of credentials to remember. That’s why a lot of IT admins ask us how to implement RADIUS authentication using their existing Microsoft Office 365 user credentials.

Why RADIUS is Important

Before we can answer that question, it’s important to understand why RADIUS is important. It’s safe to say that most modern organizations are using WiFi. The benefits to doing so are obvious, but WiFi networks don’t come without their own set of risks and challenges. Perhaps the greatest challenge comes from managing WiFi authentication to prevent unauthorized individuals from accessing the network.

Most organizations attempt to resolve this issue with ashared SSID and password. This approach can be effective in some cases. If an organization is small enough it might be easier to simply change the password and let everyone know. However, this approach is far from ideal – especially as an organization grows. For example, this approach means that anyone with the SSID and password can potentially access the an organization’s network resources. Unfortunately, that can include unwanted users like disgruntled former employees, former guests, really anyone that had access at (Read more...)
